Getting Started

Run from executable

1. Download Passkey-v1.0.0-x64.exe or Passkey-v1.0.0-x86.exe depending on your architecture.

   File	SHA-256
   Passkey-v1.0.0-x64.exe	5d858333145b586a57ea9f476197fea4649801c9705224003ec863f7791cc547
   Passkey-v1.0.0-x86.exe	cf159d6205d35d58bcfb6b2b71014c72fef08e27fe19048d50acbae7bdf85621

Deriver Panel

The Deriver panel allows a key of variable length to be derived from a password using the PBKDF2 algorithm.

• 👁: reveals the password.
• Key Length (in bytes): the desired length of the key in bytes.
• Slider: adjusts the key length.
• Iterations: sets the number of iterations in the derivation.
• Algorithm Dropdown: sets the hashing algorithm.
• Salt: adds a randomly generated salt to the password before derivation.
• 🔄: generates a new random salt and recomputes the key.
• 📋: copies a value to the clipboard.
• ❔: opens the README on GitHub.

Generator Panel

The Generator panel allows creation of a symmetric or asymmetric key pair using the RSA or ECDSA algorithms.

Symmetric Panel

• Key Length (in bytes): the desired length of the key in bytes.
• Slider: adjusts the key length.
• 🔄: recomputes a new key.
• 📋: copies a value to the clipboard.

Asymmetric Panel

• 🔄: recomputes a new key pair.
• 📋: copies a value to the clipboard.
