On a general basis, you all keys should be distinct, so you would need four keys (one for HMAC and one for encryption, in each direction). CrackStation uses massive pre-computed lookup tables to crack password hashes. John The Ripper Hash Formats John the Ripper is a favourite password cracking tool of many pentesters. new (key [, msg [, digestmod]]) ¶ Return a new hmac object. if SHA1 can not be decryoted what other option should I use to encrypt the passwords? SHA1 is a hashing algorithm which is a one way transforamtion. To generate a 768-bit DSA key for the domain example. Hence, below is the tool to generate RSA key online. SL_HMAC_CalculateHex : Calculates the HMAC for a continuous block of memory.
