How to hash long passwords (>72 characters) with blowfish
The problem here is basically a problem of entropy. So let’s start looking there: Entropy Per Character The number of bits of entropy per byte are: Hex Characters Bits: 4 Values: 16 Entropy In 72 Chars: 288 bits Alpha-Numeric Bits: 6 Values: 62 Entropy In 72 Chars: 432 bits “Common” Symbols Bits: 6.5 Values: 94 … Read more
AES vs Blowfish for file encryption
Probably AES. Blowfish was the direct predecessor to Twofish. Twofish was Bruce Schneier’s entry into the competition that produced AES. It was judged as inferior to an entry named Rijndael, which was what became AES. Interesting aside: at one point in the competition, all the entrants were asked to give their opinion of how the … Read more
Comparison of DES, Triple DES, AES, blowfish encryption for data
Use AES. In more details: DES is the old “data encryption standard” from the seventies. Its key size is too short for proper security (56 effective bits; this can be brute-forced, as has been demonstrated more than ten years ago). Also, DES uses 64-bit blocks, which raises some potential issues when encrypting several gigabytes of … Read more
