Class PasswordCipher

java.lang.Object

org.fcrepo.server.journal.helpers.PasswordCipher

public class PasswordCipher
extends Object

Encipher the password so we aren't writing it to the file in clear.

The encipher method does not allow options for cipher type. It should always use the latest and greatest. The decipher method accepts different cipher types so it can be used to read older Journal Files. Known types include:

• "" or null - empty cipher, clear text is the same as cipher text
• "1" - rotating key XOR cipher
