setAlgorithmMapping(org.bouncycastle.asn1.ASN1ObjectIdentifier algorithm,
java.lang.String algorithmName) |
Internally algorithm ids are converted into cipher names using a lookup table.

JceKeyTransRecipient |
setContentProvider(java.lang.String providerName) |
Set the provider to use for content processing.
|
JceKeyTransRecipient |
setContentProvider(java.security.Provider provider) |
Set the provider to use for content processing.
|
JceKeyTransRecipient |
setKeySizeValidation(boolean doValidate) |
Set validation of retrieved key sizes against the algorithm parameters for the encrypted key where possible - default is off.
|
JceKeyTransRecipient |
setMustProduceEncodableUnwrappedKey(boolean unwrappedKeyMustBeEncodable) |
Flag that unwrapping must produce a key that will return a meaningful value from a call to Key.getEncoded().

- the name of the provider to use.public JceKeyTransRecipient 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 java.security.Key extractSecretKey(org.bouncycastle.asn1.x509.AlgorithmIdentifier keyEncryptionAlgorithm, org.bouncycastle.asn1.x509.AlgorithmIdentifier encryptedKeyAlgorithm, byte[] encryptedEncryptionKey) throws CMSException
