getSignature

public static byte[] getSignature(byte[] forSigning0,
                                  java.security.PrivateKey key0,
                                  java.lang.String signAlg0)
                           throws SMIMEException

For creating signature values necessary information are: data for signing as byte array, type of signing algorithm, and private key for performing of asymmetric encryption.

Parameters:

forSigning0 - information for signing

key0 - private key (DSA or RSA depend on type of signing)

signAlg0 - type of signing algorithm (can be SHA1_WITH_RSA, MD2_WITH_RSA, MD5_WITH_RSA or SHA1_WITH_DSA).

Throws:

SMIMEException - caused by non SMIMEException which can be one of the following: InvalidKeyException, SignatureException, NoSuchProviderException, NoSuchAlgorithmException.
