BCrypt is based on the Blowfish block cipher cryptomatic algorithm and takes the form of an adaptive hash function. I estimate the entropy to be roughly 128 Bit (-> wikipedia password strength). Blowfish is a fast block cipher, except when changing keys. Obviously, if there were two identical blocks encrypted without any additional I am quite new to encryption and recently played around with blowfish (openssl's implemenation). I don't think decryption can be done without those keys. Your statement of the problem does not say that the the keys for AES-256 and Blowfish are not known to you. Here's the problem, a string has been passed through three separate encryptions in the following order: Original -> Base64 -> AES-256 -> Blowfish (Keyless) -> Final.

They're actually quite good (besides the don'ts I mention below). Informatica intends to drop support for Blowfish encryption in a future release. Mark's answer is also fairly accurate, smaller keys equals easier cracking time, and with larger keys it is almost impossible to brute-force. base64 string. In the real world, AES has hardware acceleration (AES-NI) that makes it very fast while being immune to cache-timing attacks. I am using a 23 character password (case-sensitive alphanumeric random). It takes a variable-length key, from 32 bits to 448 bits, making it ideal for both domestic and exportable use. Blowfish, another symmetric key encryption algorithm, could use any key with size up to 448 bits, although 128-bit keys are used most often. Blowfish is vulnerable to attacks because of its small block size that AES is not. The Default size is 128 bits.
