Class ISO9796d1Encoding

public class ISO9796d1Encoding extends Object implements AsymmetricBlockCipher

ISO 9796-1 padding. Note in the light of recent results you should only use this with RSA (rather than the "simpler" Rabin keys) and you should never use it with anything other than a hash (ie. even if the message is small don't sign the message, sign it's hash) or some "random" value. See your favorite search engine for details.
