• Key Generation: Derive keys from easy-to-remember human-readable passphrases.
  
• Encryption / Decryption: Make sure that nobody else can read your secret data.
  
• Authentication: Verify that nobody (in particular no virus) has tampered with your sensitive data.

LEDA has all you need for symmetric key cryptography!

Enhancing your application with cryptography is simple.

Have a look at an example!

It also shows you how seamlessly cryptography integrates with compression.

Some technical details:

• Block Ciphers: Rijndael(=AES), Blowfish, Twofish;
• Block Cipher Modes: ECB, CBC, CFB, OFB (for encryption) and OMAC (for authentication);
• New Checksummer: SHA-1 hashing.
