Today I was speaker at the jProfessionals conference in Sofia. My talk was about cryptography in Java: Hashes, MAC, Key Derivation, Encrypting Passwords, Symmetric Ciphers & AES, Digital Signatures & ECDSA.

I explained the concepts of Java Cryptography Architecture (JCA) and the most popular Java crypto libraries like Bouncy Castle.
