JceAsymmetricKeyWrapper

public JceAsymmetricKeyWrapper(org.spongycastle.asn1.x509.AlgorithmIdentifier algorithmIdentifier,
                               java.security.PublicKey publicKey)

Create a wrapper, overriding the algorithm type that is stored in the public key.

Parameters:

algorithmIdentifier - identifier for encryption algorithm to be used.

publicKey - the public key to be used.

JceAsymmetricKeyWrapper

public JceAsymmetricKeyWrapper(java.security.spec.AlgorithmParameterSpec algorithmParameterSpec,
                               java.security.PublicKey publicKey)

Create a wrapper, overriding the algorithm type that is stored in the public key.

Parameters:

algorithmParameterSpec - the parameterSpec for encryption algorithm to be used.

publicKey - the public key to be used.

Method Detail

setProvider

public JceAsymmetricKeyWrapper setProvider(java.security.Provider provider)

setProvider

public JceAsymmetricKeyWrapper setProvider(java.lang.String providerName)

setSecureRandom

public JceAsymmetricKeyWrapper setSecureRandom(java.security.SecureRandom random)

setAlgorithmMapping

public JceAsymmetricKeyWrapper 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 Wrapper.
