| | | | | To securely store passwords they should be hashed with a slow hashing function, such as PBKDF2. PBKDF2 is slow because it calls a fast hash function many times. This blog post explores some properties that the iterations must have to be secure. | |

| | | Motivation RSA (Rivest-Shamir-Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and is different from the decryption key which is kept secret. If I wanted to comprehend zero knowledge proofs, then understanding the grand-daddy of public-key cryptosystems is a must.
