What does a MD5 hash look like?
A MD5 hash is a 128 bits message digest represented as 32 hexadecimal characters (0-9 and A-F). For example, “700527793dc07905fd9778bad5665e44” is a MD5 hash.
This tool will help you to find if the hashs you have were generated with the MD5 algorithm or another one like SHA-1, SHA-256 or BCRYPT.
