All Implemented Interfaces:

PasswordEncryptor

public final class RFC2307MD5PasswordEncryptor
extends Object
implements PasswordEncryptor

Utility class for easily performing password digesting and checking according to {MD5}, a password encryption scheme defined in RFC2307 and commonly found in LDAP systems.

This class internally holds a StandardStringDigester configured this way:

• Algorithm: MD5.
• Salt size: 0 bytes (no salt).
• Iterations: 1 (no hash iteration).
• Prefix: {MD5}.

This class is thread-safe
