provider
- provider to use.public JceKTSKeyTransRecipient setProvider(String providerName)
providerName
- the name of the provider to use.public JceKTSKeyTransRecipient setAlgorithmMapping(org.bouncycastle.asn1.ASN1ObjectIdentifier algorithm, String algorithmName)
For example:
unwrapper.setAlgorithmMapping(PKCSObjectIdentifiers.rsaEncryption, "RSA");
algorithm
- OID of algorithm in recipient.algorithmName
- JCE algorithm name to use.public JceKTSKeyTransRecipient setContentProvider(Provider provider)
provider
- the provider to use.public JceKTSKeyTransRecipient setContentProvider(String providerName)
providerName
- the name of the provider to use.public JceKTSKeyTransRecipient setKeySizeValidation(boolean doValidate)
This setting will not have any affect if the encryption algorithm in the recipient does not specify a particular key size, or if the unwrapper is a HSM and the byte encoding of the unwrapped secret key is not available.
doValidate
- true if unwrapped key's should be validated against the content encryption algorithm, false otherwise.protected Key extractSecretKey(org.bouncycastle.asn1.x509.AlgorithmIdentifier keyEncryptionAlgorithm, org.bouncycastle.asn1.x509.AlgorithmIdentifier encryptedKeyAlgorithm, byte[] encryptedEncryptionKey) throws CMSException
