JceKeyTransRecipient

public JceKeyTransRecipient(java.security.PrivateKey recipientKey)

Method Detail

setProvider

public JceKeyTransRecipient setProvider(java.security.Provider provider)

Set the provider to use for key recovery and content processing.

Parameters:

provider - provider to use.

Returns:

this recipient.

setProvider

public JceKeyTransRecipient setProvider(java.lang.String providerName)

Set the provider to use for key recovery and content processing.

Parameters:

providerName - the name of the provider to use.

Returns:

this recipient.

setAlgorithmMapping

public JceKeyTransRecipient 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 Recipient.

setContentProvider

public JceKeyTransRecipient setContentProvider(java.security.Provider provider)

Set the provider to use for content processing. If providerName is null a "no provider" search will be used to satisfy getInstance calls.

Parameters:

provider - the provider to use.

Returns:

this recipient.

setContentProvider

public JceKeyTransRecipient setContentProvider(java.lang.String providerName)

Set the provider to use for content processing. If providerName is null a "no provider" search will be used to satisfy getInstance calls.

Parameters:

providerName - the name of the provider to use.

Returns:

this recipient.

extractSecretKey

protected java.security.Key extractSecretKey(org.bouncycastle.asn1.x509.AlgorithmIdentifier keyEncryptionAlgorithm,
                                             org.bouncycastle.asn1.x509.AlgorithmIdentifier encryptedKeyAlgorithm,
                                             byte[] encryptedEncryptionKey)
                                      throws CMSException

Throws:

CMSException
