Crypt::Blowfish - Perl Blowfish encryption module

WebJan 1, 2024 · Blowfish's flexible key length is arguably a disadvantage, since it's an invitation to use a passphrase or other non-random secret directly as a key. This is a bad idea: block cipher key setup is supposed to be as fast as possible, while passphrases should be run through a KDF that is as slow as possible. WebBlowfish is capable of strong encryption and can use key sizes up to 56 bytes (a 448 bit key).

WebNov 27, 2012 · CryptDB’s approach is to execute SQL queries over encrypted data. It can do so practically with two techniques: using a collection of efficient SQL-aware encryption schemes, two of which are new, and onions of encryptions which allow dynamic adjustment of encryption schemes. http://www.css.csail.mit.edu/cryptdb/

You cannot calculate the key from a cipher, even if you know the plaintext and encrypted data. Blowfish isn't better than MD5 or SHA512, as they serve different purposes. MD5 and SHA512 are hashing algorithms, Blowfish is an encryption algorithm.
