The documentation for Node.js and PHP's mcrypt are not clear, but it looks like Node.js uses a key derivation function, while mcrypt uses the key as-is. Since Node.js implements PBKDF2, I'm guessing that's its key derivation algorithm, but I don't see how to specify the parameters. norse careers norwich https://ridgewoodinv.com

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. WebVersion 1.3 adds support for the $2b$ prefix introduced in OpenBSD 5.5+, which behaves exactly the same as crypt_blowfish's $2y$. This way, full compatibility with OpenBSD's bcrypt is achieved at this new prefix.
