Internally algorithm ids are converted into cipher names using a lookup table. For some providers
the standard lookup table won't work. Use this method to establish a specific mapping from an
algorithm identifier to a specific algorithm.
For example:
unwrapper.setAlgorithmMapping(PKCSObjectIdentifiers.rsaEncryption, "RSA");
Params: - algorithm – OID of algorithm in recipient.
- algorithmName – JCE algorithm name to use.
Returns: the current RecipientInfoGenerator.
