Class RC2WrapEngine
java.lang.Object
|
+--org.bouncycastle.crypto.engines.RC2WrapEngine
- All Implemented Interfaces:
- Wrapper
- public class RC2WrapEngine
- extends java.lang.Object
- implements Wrapper
Wrap keys according to
draft-ietf-smime-key-wrap-01.txt.
Note:
- this is based on a draft, and as such is subject to change - don't use this class for anything requiring long term storage.
- if you are using this to wrap triple-des keys you need to set the
parity bits on the key and, if it's a two-key triple-des key, pad it
yourself.
