Cryptographic hash function with a 128-bit (16-byte) hash value. MD5 is no longer considered a secure hash and should not be used to protect sensitive information like passwords

MD5 is incredibly weak on modern computers, and can be easily broken. If you are looking to securely hash values, consider something stronger like bcrypt

MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function with a 128-bit (16-byte) hash value. Specified in RFC 1321, MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. However, it has been shown that MD5 is not collision resistant; as such, MD5 is not suitable for applications like SSL certificates or digital signatures that rely on this property. An MD5 hash is typically expressed as a 32-digit hexadecimal number.
