JceKeyTransRecipientInfoGenerator

public JceKeyTransRecipientInfoGenerator(java.security.cert.X509Certificate recipientCert,
                                         org.spongycastle.asn1.x509.AlgorithmIdentifier algorithmIdentifier)
                                  throws java.security.cert.CertificateEncodingException

Create a generator overriding the algorithm type implied by the public key in the certificate passed in.

Parameters:

recipientCert - certificate carrying the public key.

algorithmIdentifier - the identifier and parameters for the encryption algorithm to be used.

Throws:

java.security.cert.CertificateEncodingException

JceKeyTransRecipientInfoGenerator

public JceKeyTransRecipientInfoGenerator(byte[] subjectKeyIdentifier,
                                         org.spongycastle.asn1.x509.AlgorithmIdentifier algorithmIdentifier,
                                         java.security.PublicKey publicKey)

Create a generator overriding the algorithm type implied by the public key passed in.

Parameters:

subjectKeyIdentifier - the subject key identifier value to associate with the public key.

algorithmIdentifier - the identifier and parameters for the encryption algorithm to be used.

publicKey - the public key to use.

Method Detail

setProvider

public JceKeyTransRecipientInfoGenerator setProvider(java.lang.String providerName)

setProvider

public JceKeyTransRecipientInfoGenerator setProvider(java.security.Provider provider)

setAlgorithmMapping

public JceKeyTransRecipientInfoGenerator setAlgorithmMapping(org.spongycastle.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 RecipientInfoGenerator.
