public class Password
- extends Credential
Password utility class.
This utility class gets a password or pass phrase either by:
+ Password is set as a system property.
+ The password is prompted for and read from standard input
+ A program is run to get the password.
Passwords that begin with OBF: are de obfuscated.
Passwords can be obfuscated by run org.mortbay.util.Password as a
main class. Obfuscated password are required if a system needs
to recover the full password (eg. so that it may be passed to another
system). They are not secure, but prevent casual observation.
Passwords that begin with CRYPT: are oneway encrypted with
UnixCrypt. The real password cannot be retrieved, but comparisons
can be made to other passwords. A Crypt can be generated by running
org.mortbay.util.UnixCrypt as a main class, passing password and
then the username. Checksum passwords are a secure(ish) way to
store passwords that only need to be checked rather
than recovered. Note that it is not strong security - specially if
simple passwords are used.
