java.lang.Object
org.apache.cayenne.configuration.Rot13PasswordEncoder
- All Implemented Interfaces:
- PasswordEncoding
public class Rot13PasswordEncoder extends Object implements PasswordEncoding
The ROT-13 password encoder passes the text of the database password through a simple
 Caesar cipher to obscure the password text. The ROT-13 cipher only processes letters --
 numbers and symbols are left untouched. ROT-13 is also a symmetrical cipher and
 therefore provides no real encryption since applying the cipher to the encrypted text
 produces the original source text. See the Wikipedia entry on ROT13 for more information on this
 topic.

decodePasswordDescription copied from interface:PasswordEncodingDecodes an encoded database password.- Specified by:
- decodePasswordin interface- PasswordEncoding
- Parameters:
- encodedPassword- - The encoded password to be decoded
- key- - An optional data element which can be used to unlock the password. Some encoders may require the key.
- Returns:
- The decoded normal/plain password.

encodePasswordDescription copied from interface:PasswordEncodingEncodes a normal/plain database password.- Specified by:
- encodePasswordin interface- PasswordEncoding
- Parameters:
- normalPassword- - The normal/plain password to be encoded
- key- - An optional data element which can be used to lock the password. Some encoders may require the key.
- Returns:
- The encoded password.

rotateApplies a ROT-13 Caesar cipher to the supplied value. Each letter in the supplied value is substituted with a new value rotated by 13 places in the alphabet. See ROT13 for more information.A Unix command to perform a ROT-13 cipher is: tr "[a-m][n-z][A-M][N-Z]" "[n-z][a-m][N-Z][A-M]" - Parameters:
- value- The text to be rotated.
- Returns:
- The rotated text.
