Method Detail

setProvider

public JceAsymmetricKeyUnwrapper setProvider(java.security.Provider provider)

setProvider

public JceAsymmetricKeyUnwrapper setProvider(java.lang.String providerName)

setAlgorithmMapping

public JceAsymmetricKeyUnwrapper setAlgorithmMapping(org.bouncycastle.asn1.ASN1ObjectIdentifier algorithm,
                                                     java.lang.String algorithmName)

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");
 

Parameters:

algorithm - OID of algorithm in recipient.

algorithmName - JCE algorithm name to use.

Returns:

the current Unwrapper.

                                throws OperatorException

Throws:

OperatorException
