Class UnixCrypt
java.lang.Object
org.apache.commons.codec.digest.UnixCrypt
Unix crypt(3) algorithm implementation.
 
This class only implements the traditional 56 bit DES based algorithm. Please use Crypt.crypt() for a method that distinguishes between all the algorithms supported in the current glibc's crypt().
The initial 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.

Method Details- 
cryptGenerates a crypt(3) compatible hash using the DES algorithm.A salt is generated for you using SecureRandom.- Parameters:
- original- plaintext password
- Returns:
- a 13 character string starting with the salt string
 
- 
cryptGenerates a crypt(3) compatible hash using the DES algorithm.Using unspecified characters as salt results incompatible hash values. - Parameters:
- original- plaintext password
- salt- a two character string drawn from [a-zA-Z0-9./]. The salt may be null, in which case a salt is generated for you using- B64.getRandomSalt(int). Only the first two characters are used, others are ignored.
- Returns:
- a 13 character string starting with the salt string
- Throws:
- IllegalArgumentException- if the salt does not match the allowed pattern
