com.entrust.toolkit.security.crypto.rsa.RsaPkcs1v1_5SignatureImplKeychain

public class RsaPkcs1v1_5SignatureImplKeychain
extends com.entrust.toolkit.security.crypto.rsa.RsaSignatureImpl

This class implements the RSAPKCS1v1.5 Signature implementation in the Keychain. The Keychain does the work of adding the Der encoded Digest Algorithm Identifier and formats the PKCS1.5 message before it signs. Therefore, this class does not need to use the DerEncodedDigestInfoPrefix

Since:

9.0

Method Detail

engineInit

protected void engineInit(java.security.PublicKey publicKey,
                          java.security.spec.AlgorithmParameterSpec params)
                   throws java.security.InvalidKeyException

Constructor for initializing with a PublicKey. Since Signature verification is not supported in the Keychain at this time, an exception is thrown.

Specified by:

engineInit in class com.entrust.toolkit.security.crypto.signature.DigitalSignatureWithSoftDigestImpl

Throws:

java.security.InvalidKeyException
