setAlgorithmMapping	back to summary
public JceAsymmetricKeyWrapper setAlgorithmMapping(ASN1ObjectIdentifier algorithm, 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:ASN1ObjectIdentifier OID of algorithm in recipient. algorithmName:String JCE algorithm name to use. Returns:JceAsymmetricKeyWrapper the current Wrapper.

setAlgorithmMapping

back to summary

public JceAsymmetricKeyWrapper setAlgorithmMapping(ASN1ObjectIdentifier algorithm, 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:ASN1ObjectIdentifier: OID of algorithm in recipient.
algorithmName:String: JCE algorithm name to use.

Returns:JceAsymmetricKeyWrapper
