Hashing passwords with a salt - why use different salt for everyone? The unique salt per password is there to prevent an attacker from amortizing his effort over many passwords. If you use the same salt for n passwords you make his job easier by a factor of n. Note that the salt is not secret. |

Is modern encryption needlessly complicated? AES is much faster than your Blum-Blum-Shub setup. |

What alphanumeric string length can be used to guarantee no hash collisions from CRC-64? Assuming a standard encoding of characters as 8 bit bytes you can guarantee uniqueness only up to 8 characters. |

Why does PBKDF2 xor the iterations of the hash function together? I wonder why they don't also hash the counter i for U_i? |
