Security

The libsodium library is used for all cryptography. You can read the full technical details here.

Functionality

  • Encrypt files/folders with a password, keyfile, or asymmetric keys.

  • Create and verify digital signatures, with support for an authenticated comment and prehashing.​

  • Generation of asymmetric key pairs. The private key is encrypted for protection at rest.​

  • UNIX style password entry and random passphrase generation.

  • Encrypting files using a recipient's public key allows for authenticated, one-way file sharing.​

  • Random keyfile generation. Any type of file can also be used as a keyfile.

  • Obfuscate output file names when encrypting files/folders.

  • Overwrite input files when encrypting files/folders.

Privacy

  • Kryptor runs locally on your computer. No personal data is ever collected or sent to anyone.​

  • Kryptor runs offline unless you run the -u|--update command, which downloads a text file from GitHub. You can read GitHub's Privacy Policy here.
