WebApr 12, 2024 · 1 Answer. SHA-512 is a cryptographic hash while bcrypt is a password hash or PBKDF (password based key derivation function). SHA-512 has been designed to be fast. You don't want any delays when validating a signature, for instance. There is no reason for generic cryptographic hashes to be slow. WebThis makes it irreversible, essentially a hashing function. 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, …

WebComparison Table. Blowfish is the first symmetric encryption algorithm created by Bruce Schneier in 1993. Symmetric encryption uses a single encryption key to both encrypt and decrypt data. The sensitive data and the symmetric encryption key are utilized within the encryption algorithm to turn the sensitive data into ciphertext. WebBlowfish is an encryption algorithm that can be used as a replacement for the DES or IDEA algorithms.

WebJan 27, 2024 · 2. You haven't mentioned your use case, but generally, if it's a modern htpasswd implementation, it's generating a $2a$-compatible hash (null-terminated, UTF-8 encoded), even though it's using $2y$ to label the variant. In other words, you could probably literally replace the 2y with 2a, and it should work. This StackOverflow answer … WebThis is an implementation of bcrypt, a password hashing method based on the Blowfish block cipher, provided via the crypt(3) and a reentrant interface.
