Method Detail

sign

public void sign(java.io.File input,
                 java.io.File output,
                 PrivateKey privateKey)

Description copied from interface: IAsymmetricCipher

This method offers a facility to sign files with asymmetric cryptography.

Specified by:

sign in interface IAsymmetricCipher

Parameters:

input - The input file to be signed against an asymmetric private key.

output - The output file signed against the asymmetric private key.

privateKey - The private asymmetric key to use in the signing process.

checkSignature

public boolean checkSignature(java.io.File signedInputFile,
                              java.io.File dataFile,
                              PublicKey publicKey)

Description copied from interface: IAsymmetricCipher

This method offers a facility to check the signature of a file with asymmetric cryptography.

Specified by:

checkSignature in interface IAsymmetricCipher

Parameters:

signedInputFile - The input file whose signature must be checked against an asymmetric public key.

dataFile - The input data file whose signature must be checked against an asymmetric public key.

publicKey - The public key to use in the check signature process.

Returns:

True if the input file is valid signed file against the public key, false otherwise.
