Method Detail

getRID

public RecipientId getRID()

getKeyEncryptionAlgOID

public java.lang.String getKeyEncryptionAlgOID()

return the object identifier for the key encryption algorithm.

Returns:

OID for key encryption algorithm.

getKeyEncryptionAlgParams

public byte[] getKeyEncryptionAlgParams()

return the ASN.1 encoded key encryption algorithm parameters, or null if there aren't any.

Returns:

ASN.1 encoding of key encryption algorithm parameters.

getKeyEncryptionAlgorithmParameters

public java.security.AlgorithmParameters getKeyEncryptionAlgorithmParameters(java.lang.String provider)
                                                                      throws CMSException,
                                                                             java.security.NoSuchProviderException

Return an AlgorithmParameters object giving the encryption parameters used to encrypt the key this recipient holds.

Parameters:

provider - the provider to generate the parameters for.

Returns:

the parameters object, null if there is not one.

Throws:

CMSException - if the algorithm cannot be found, or the parameters can't be parsed.

java.security.NoSuchProviderException - if the provider cannot be found.

getKeyEncryptionAlgorithmParameters

public java.security.AlgorithmParameters getKeyEncryptionAlgorithmParameters(java.security.Provider provider)
                                                                      throws CMSException

Return an AlgorithmParameters object giving the encryption parameters used to encrypt the key this recipient holds.

Parameters:

provider - the provider to generate the parameters for.

Returns:

the parameters object, null if there is not one.

Throws:

CMSException - if the algorithm cannot be found, or the parameters can't be parsed.
