WebAn MD5 hash is created by taking a string of an any length and encoding it into a 128-bit fingerprint. Encoding the same string using the MD5 algorithm will always result in the same 128-bit hash output. WebMD5 Hash Properties. The MD5 hash consists of a small amount of binary data, typically no more than 128 bits. All hash values share the following properties: Hash length. The …

WebSep 30, 2016 · The main reason you shouldn't use MD5 is because it is a General Purpose (Fast) Hash. BCrypt is commonly recommended, but be sure to run a quick SHA-2 hash on the input data, so super-long passwords will not be truncated by BCrypt. PBKDF2 but that is less GPU-resistant because it has lower Memory requirements. WebMD5 outputs an 128-bit hash value. Or: there are 2 128 possible outputs.
