public class UnixCrypt extends Object
This class only implements the traditional 56 bit DES based algorithm. Please use DigestUtils.crypt() for a method that distinguishes between all the algorithms supported in the current glibc's crypt().
The Java implementation was taken from the JetSpeed Portal project (see org.apache.jetspeed.services.security.ldap.UnixCrypt).
This class is slightly incompatible if the given salt contains characters that are not part of the allowed range [a-zA-Z0-9./].
This class is immutable and thread-safe.

As no salt is given, a random one will be used.

Using unspecified characters as salt results incompatible hash values.
