(The last version with support for Swift 3.x was BigInt 2.1.0. +The last version with support for Swift 2 was BigInt 1.3.0.) + +BigInt deploys to macOS 10.10, iOS 9, watchOS 2 and tvOS 9. +It has been tested on the latest OS releases only---however, as the module uses very few platform-provided APIs, +there should be very few issues with earlier versions. + +BigInt uses no APIs specific to Apple platforms except for `arc4random_buf` in `BigUInt Random.swift`, so +it should be easy to port it to other operating systems. + +Setup instructions: + +- **Swift Package Manager:** + Although the Package Manager is still in its infancy, BigInt provides experimental support for it. + Add this to the dependency section of your `Package.swift` manifest: + + ```Swift + .Package(url: "https://github.com/attaswift/BigInt.git", from: "3.1.0") + ``` + +- **CocoaPods:** Put this in your `Podfile`: + + ```Ruby + pod 'BigInt', '~> 3.1' + ``` + +- **Carthage:** Put this in your `Cartfile`: + + ``` + github "attaswift/BigInt" ~> 3.1 + ``` + + +## Implementation notes + +[`BigUInt`][BigUInt] is a `MutableCollectionType` of its 64-bit digits, with the least significant +digit at index 0. As a convenience, [`BigUInt`][BigUInt] allows you to subscript it with indexes at +or above its `count`. [The subscript operator][subscript] returns 0 for out-of-bound `get`s and +automatically extends the array on out-of-bound `set`s. This makes memory management simpler. + +[`BigInt`][BigInt] is just a tiny wrapper around a `BigUInt` [absolute value][abs] and a +[sign bit][negative], both of which are accessible as public read-write properties. + +### Full-width multiplication and division primitives + +I haven't found (64,64)->128 multiplication or (128,64)->64 division operations +in Swift, so [the module has generic implementations for them][fullmuldiv] in terms of the standard +single-width `*` and `/` operators. I suspect there are LLVM intrinsics for full-width +arithmetics that are probably accessible somehow, though. ([Let me know][twitter] if you know how!) + +This sounds slow, but 64-bit digits are +still considerably faster than 32-bit, even though the latter can use direct 64-bit arithmetic to +implement these primitives. + +### Why is there no generic `BigInt` type? + +The types provided by `BigInt` are not parametric—this is very much intentional, as +Swift generics cost us dearly at runtime in this use case. In every approach I tried, +making arbitrary-precision arithmetic operations work with a generic `Digit` type parameter +resulted in code that was literally *ten times slower*. If you can make the algorithms generic +without such a huge performance hit, [please enlighten me][twitter]! + +This is an area that I plan to investigate more, as it would be useful to have generic +implementations for arbitrary-width arithmetic operations. (Polynomial division and decimal bases +are two examples.) The library already implements double-digit multiplication and division as +extension methods on a protocol with an associated type requirement; this has not measurably affected +performance. Unfortunately, the same is not true for `BigUInt`'s methods. + +Of course, as a last resort, we could just duplicate the code to create a separate +generic variant that was slower but more flexible. +

Of course it does! + +```Swift +var digits = "π ≈ " +var count = 0 +for digit in digitsOfPi() { + assert(digit < 10) + digits += String(digit) + count += 1 + if count == 1 { digits += "." } + if count == 1000 { break } +} + +digits +==> π ≈ 3.14159265358979323846264338327950288419716939937510582097494459230781640628 + 62089986280348253421170679821480865132823066470938446095505822317253594081284811 + 17450284102701938521105559644622948954930381964428810975665933446128475648233786 + 78316527120190914564856692346034861045432664821339360726024914127372458700660631 + 55881748815209209628292540917153643678925903600113305305488204665213841469519415 + 11609433057270365759591953092186117381932611793105118548074462379962749567351885 + 75272489122793818301194912983367336244065664308602139494639522473719070217986094 + 37027705392171762931767523846748184676694051320005681271452635608277857713427577 + 89609173637178721468440901224953430146549585371050792279689258923542019956112129 + 02196086403441815981362977477130996051870721134999999837297804995105973173281609 + 63185950244594553469083026425223082533446850352619311881710100031378387528865875 + 33208381420617177669147303598253490428755468731159562863882353787593751957781857 + 780532171226806613001927876611195909216420198 +``` + +Now go and have some fun with big integers on your own! diff --git a/Pods/BigInt/sources/Addition.swift b/Pods/BigInt/sources/Addition.swift new file mode 100644 index 00000000..34f4d44e --- /dev/null +++ b/Pods/BigInt/sources/Addition.swift @@ -0,0 +1,126 @@ +// +// Addition.swift +// BigInt +// +// Created by Károly Lőrentey on 2016-01-03. +// Copyright © 2016-2017 Károly Lőrentey. +// + +extension BigUInt { + //MARK: Addition + + /// Add `word` to this integer in place. + /// `word` is shifted `shift` words to the left before being added. + /// + /// - Complexity: O(max(count, shift)) + internal mutating func addWord(_ word: Word, shiftedBy shift: Int = 0) { + precondition(shift >= 0) + var carry = word + var i = shift + while carry > 0 { + let (d, c) = self[i].addingReportingOverflow(carry) + self[i] = d + carry = (c ? 1 : 0) + i += 1 + } + } + + /// Add the digit `d` to this integer and return the result. + /// `d` is shifted `shift` words to the left before being added. + /// + /// - Complexity: O(max(count, shift)) + internal func addingWord(_ word: Word, shiftedBy shift: Int = 0) -> BigUInt { + var r = self + r.addWord(word, shiftedBy: shift) + return r + } + + /// Add `b` to this integer in place. + /// `b` is shifted `shift` words to the left before being added. + /// + /// - Complexity: O(max(count, b.count + shift)) + internal mutating func add(_ b: BigUInt, shiftedBy shift: Int = 0) { + precondition(shift >= 0) + var carry = false + var bi = 0 + let bc = b.count + while bi < bc || carry { + let ai = shift + bi + let (d, c) = self[ai].addingReportingOverflow(b[bi]) + if carry { + let (d2, c2) = d.addingReportingOverflow(1) + self[ai] = d2 + carry = c || c2 + } + else { + self[ai] = d + carry = c + } + bi += 1 + } + } + + /// Add `b` to this integer and return the result. + /// `b` is shifted `shift` words to the left before being added. + /// + /// - Complexity: O(max(count, b.count + shift)) + internal func adding(_ b: BigUInt, shiftedBy shift: Int = 0) -> BigUInt { + var r = self + r.add(b, shiftedBy: shift) + return r + } + + /// Increment this integer by one.

The other +extensions are available by specifying additional subspecs in your `Podfile`, +e.g.: + +```ruby +pod "PromiseKit/MapKit" # MKDirections().calculate().then { /*…*/ } +pod "PromiseKit/CoreLocation" # CLLocationManager.requestLocation().then { /*…*/ } +``` + +All our extensions are separate repositories at the [PromiseKit organization]. + +## I don't want the extensions! + +Then don’t have them: + +```ruby +pod "PromiseKit/CorePromise", "~> 6.0" +``` + +> *Note:* Carthage installations come with no extensions by default. + +## Choose Your Networking Library + +Promise chains commonly start with a network operation. Thus, we offer +extensions for `URLSession`: + +```swift +// pod 'PromiseKit/Foundation' # https://github.com/PromiseKit/Foundation + +firstly { + URLSession.shared.dataTask(.promise, with: try makeUrlRequest()).validate() + // ^^ we provide `.validate()` so that eg. 404s get converted to errors +}.map { + try JSONDecoder().decode(Foo.self, with: $0.data) +}.done { foo in + //… +}.catch { error in + //… +} + +func makeUrlRequest() throws -> URLRequest { + var rq = URLRequest(url: url) + rq.httpMethod = "POST" + rq.addValue("application/json", forHTTPHeaderField: "Content-Type") + rq.addValue("application/json", forHTTPHeaderField: "Accept") + rq.httpBody = try JSONEncoder().encode(obj) + return rq +} +``` + +And [Alamofire]: + +```swift +// pod 'PromiseKit/Alamofire' # https://github.com/PromiseKit/Alamofire- + +firstly { + Alamofire + .request("http://example.com", method: .post, parameters: params) + .responseDecodable(Foo.self) +}.done { foo in + //… +}.catch { error in + //… +} +``` + +Nowadays, considering that: + +* We almost always POST JSON +* We now have `JSONDecoder` +* PromiseKit now has `map` and other functional primitives +* PromiseKit (like Alamofire, but not raw-URLSession) also defaults to having callbacks go to the main thread + +We recommend vanilla `URLSession`. It uses fewer black boxes and sticks closer to the +metal.

This is similar to Swift’s native `Optional` type: `success` is like `some`, and `failure` is like `none` except with an associated `Error` value. The addition of an associated `Error` allows errors to be passed along for logging or displaying to the user. + +Using this µframework instead of rolling your own `Result` type allows you to easily interface with other frameworks that also use `Result`. + +## Use + +Use `Result` whenever an operation has the possibility of failure. Consider the following example of a function that tries to extract a `String` for a given key from a JSON `Dictionary`. + +```swift +typealias JSONObject = [String: Any] + +enum JSONError: Error { + case noSuchKey(String) + case typeMismatch +} + +func stringForKey(json: JSONObject, key: String) -> Result { + guard let value = json[key] else { + return .failure(.noSuchKey(key)) + } + + if let value = value as? String { + return .success(value) + } + else { + return .failure(.typeMismatch) + } +} +``` + +This function provides a more robust wrapper around the default subscripting provided by `Dictionary`. Rather than return `Any?`, it returns a `Result` that either contains the `String` value for the given key, or an `ErrorType` detailing what went wrong. + +One simple way to handle a `Result` is to deconstruct it using a `switch` statement. + +```swift +switch stringForKey(json, key: "email") { + +case let .success(email): + print("The email is \(email)") + +case let .failure(.noSuchKey(key)): + print("\(key) is not a valid key") + +case .failure(.typeMismatch): + print("Didn't have the right type") +} +``` + +Using a `switch` statement allows powerful pattern matching, and ensures all possible results are covered. Swift 2.0 offers new ways to deconstruct enums like the `if-case` statement, but be wary as such methods do not ensure errors are handled. + +Other methods available for processing `Result` are detailed in the [API documentation](http://cocoadocs.org/docsets/Result/). + +## Result vs. Throws + +Swift 2.0 introduces error handling via throwing and catching `Error`. `Result` accomplishes the same goal by encapsulating the result instead of hijacking control flow. The `Result` abstraction enables powerful functionality such as `map` and `flatMap`, making `Result` more composable than `throw`. + +Since dealing with APIs that throw is common, you can convert such functions into a `Result` by using the `materialize` method. Conversely, a `Result` can be used to throw an error by calling `dematerialize`. + +## Higher Order Functions + +`map` and `flatMap` operate the same as `Optional.map` and `Optional.flatMap` except they apply to `Result`. + +`map` transforms a `Result` into a `Result` of a new type. It does this by taking a function that transforms the `Value` type into a new value. This transformation is only applied in the case of a `success`. In the case of a `failure`, the associated error is re-wrapped in the new `Result`. + +```swift +// transforms a Result to a Result +let idResult = intForKey(json, key:"id").map { id in String(id) } +``` + +Here, the final result is either the id as a `String`, or carries over the `failure` from the previous result. + +`flatMap` is similar to `map` in that it transforms the `Result` into another `Result`. However, the function passed into `flatMap` must return a `Result`. + +An in depth discussion of `map` and `flatMap` is beyond the scope of this documentation. If you would like a deeper understanding, read about functors and monads. This article is a good place to [start](http://www.javiersoto.me/post/106875422394). + +## Integration + +### Carthage + +1.

But how many collisions are "too many"? Do we even know what +our "typical inputs" look like? For me, the answer to both of these questions is usually "I have absolutely no idea", +and I bet you have the same problem. + +Thus, verifying that our `hashValue` implementations work well is an exercise in frustration. + +We need to somehow check the properties of the hash function by looking at its behavior given various inputs. +It is easy enough to write tests for the requirement that equal values have equal `hashValues`. +But verifying that the hash has few collisions requires making some assumptions on the +statistical properties of "typical" inputs -- and even if we'd be somehow confident enough to do that, writing the code +to do it is way too complicated. + +Instead of rolling your own ad-hoc hash function, why not just use an algorithm designed specifically to blend data +into a hash? Using a standardized algorithm means we don't need to worry about collision behavior any more: if the +algorithm was designed well, we'll always have good results. + +The SipHash algorithm is a particularly good choice for hashing. It implements a 64-bit cryptographic +message-authentication code (MAC) with a 256-bit internal state initialized from a 128-bit secret key that's (typically) +randomly generated for each execution of the binary. +SipHash is designed to protect against hash collision attacks, while remaining simple to use and fast. +It is already used by Perl, Python, Ruby, Rust, and even Swift itself -- which is why the documentation of `Hashable` +explicitly warns that the value returned by `hashValue` may be different across executions. + +The standard library already implements SipHash, but the implementation is private. (It is technically available +for use, but it is not formally part of the stdlib API, and it is subject to change/removal across even point releases.) +I expect a refactored version of stdlib's SipHash will become available as public API in a future Swift release. +But while we're waiting for that, this package provides an alternative implementation that is available today. + +## Is this code full of bugs? + +Indubitably. Please report all bugs you find! + +The package has 100% unit test coverage. Unfortunately this doesn't tell you much about its reliability in practice. + +The test suite verifies that the package generates values that match the test vectors supplied by SipHash's original +authors, which makes me reasonably confident that this package implements SipHash correctly. +Obviously, your mileage may vary. + +## Reference docs + +[Nicely formatted reference docs][docs] are available courtesy of [Jazzy]. + +[docs]: https://attaswift.github.io/SipHash/ +[Jazzy]: https://github.com/realm/jazzy + +## Installation + +### CocoaPods + +If you use CocoaPods, you can start using `SipHash` by including it as a dependency in your `Podfile`: + +``` +pod 'SipHash', '~> 1.2' +``` + +### Carthage + +For Carthage, add the following line to your `Cartfile`: + +``` +github "attaswift/SipHash" ~> 1.2 +``` + +### Swift Package Manager + +For Swift Package Manager, add `SipHash` to the dependencies list inside your `Package.swift` file: + +``` +import PackageDescription + +let package = Package( + name: "MyPackage", + dependencies: [ + .Package(url: "https://github.com/attaswift/SipHash.git", from: "1.2.1") + ] +) +``` + +### Standalone Development + +If you don't use a dependency manager, you need to clone this repo somewhere near your project, and add a reference to `SipHash.xcodeproj` to your project's `xcworkspace`. You can put the clone of SipHash wherever you like on disk, but it is a good idea to set it up as a submodule of your app's top-level Git repository. + +To link your application binary with SipHash, just add `SipHash.framework` from the SipHash project to the Embedded Binaries section of your app target's General page in Xcode. As long as the SipHash project file is referenced in your workspace, this framework will be listed in the "Choose items to add" sheet that opens when you click on the "+" button of your target's Embedded Binaries list. + +There is no need to do any additional setup beyond adding the framework targets to Embedded Binaries. diff --git a/Pods/SipHash/SipHash/Primitive Types.swift b/Pods/SipHash/SipHash/Primitive Types.swift new file mode 100644 index 00000000..45824562 --- /dev/null +++ b/Pods/SipHash/SipHash/Primitive Types.swift @@ -0,0 +1,171 @@ +// +// Primitive Types.swift +// SipHash +// +// Created by Károly Lőrentey on 2016-11-14. +// Copyright © 2016-2017 Károly Lőrentey. +// + +extension SipHasher { + //MARK: Appending buffer slices + + /// Add the contents of `slice` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ slice: Slice) { + self.append(UnsafeRawBufferPointer(rebasing: slice)) + } + + //MARK: Appending Integers + + /// Add `value` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ value: Bool) { + var data = value + append(UnsafeRawBufferPointer(start: &data, count: MemoryLayout.size)) + } + + /// Add `value` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ value: Int) { + var data = value + append(UnsafeRawBufferPointer(start: &data, count: MemoryLayout.size)) + } + + /// Add `value` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ value: UInt) { + var data = value + append(UnsafeRawBufferPointer(start: &data, count: MemoryLayout.size)) + } + + /// Add `value` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ value: Int64) { + var data = value + append(UnsafeRawBufferPointer(start: &data, count: MemoryLayout.size)) + } + + /// Add `value` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ value: UInt64) { + var data = value + append(UnsafeRawBufferPointer(start: &data, count: MemoryLayout.size)) + } + + /// Add `value` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ value: Int32) { + var data = value + append(UnsafeRawBufferPointer(start: &data, count: MemoryLayout.size)) + } + + /// Add `value` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ value: UInt32) { + var data = value + append(UnsafeRawBufferPointer(start: &data, count: MemoryLayout.size)) + } + + /// Add `value` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ value: Int16) { + var data = value + append(UnsafeRawBufferPointer(start: &data, count: MemoryLayout.size)) + } + + /// Add `value` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ value: UInt16) { + var data = value + append(UnsafeRawBufferPointer(start: &data, count: MemoryLayout.size)) + } + + /// Add `value` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ value: Int8) { + var data = value + append(UnsafeRawBufferPointer(start: &data, count: MemoryLayout.size)) + } + + /// Add `value` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ value: UInt8) { + var data = value + append(UnsafeRawBufferPointer(start: &data, count: MemoryLayout.size)) + } +} + +extension SipHasher { + //MARK: Appending Floating Point Types + + /// Add `value` to this hash. + /// + /// - Requires: `finalize()` hasn't been called on this instance yet. + public mutating func append(_ value: Float) { + var data = value.isZero ?

The Swift Package Manager version supports macOS and Linux. + +We try to merge bug fix commits ASAP and only change the import and config structure of the original repository in order to create a compilable version for the package managers. + +All credits for the original source code goes to [bitcoin-core](https://github.com/bitcoin-core). + +> Note: This library only binds the original C code into a Swift package. If you want an Ethereum Web3 package which manages signatures and verifications, check out [Web3.swift](https://github.com/Boilertalk/Web3.swift) + +## Example + +To run the example project, run `pod try secp256k1.swift`. Or clone the repo, and run pod install from the Example directory. + +## Installation + +### CocoaPods + +secp256k1 is available through [CocoaPods](http://cocoapods.org). To install +it, simply add the following line to your `Podfile`: + +```ruby +pod 'secp256k1.swift' +``` + +### Carthage + +secp256k1 is compatible with [Carthage](https://github.com/Carthage/Carthage), a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To install it, simply add the following line to your `Cartfile`: + +``` +github "Boilertalk/secp256k1.swift" +``` + +### Swift Package Manager + +secp256k1 is compatible with Swift Package Manager v4 (Swift 4 and above). Simply add it to the dependencies in your `Package.swift`. + +```Swift +dependencies: [ + .package(url: "https://github.com/Boilertalk/secp256k1.swift.git", from: "0.1.0") +] +``` + +## Usage + +To use secp256k1 functions you need to import it first. + +```Swift +import secp256k1 +``` + +After that you can use all secp256k1 functions as described [in the official headers](https://github.com/bitcoin-core/secp256k1/tree/master/include). + +## Author + +Koray Koska, koray@koska.at + +## License + +secp256k1 is available under the MIT license.
