Method Summary

boolean	checkSignature(java.io.File signedFile, java.io.File dataFile, PublicKey publicKey) This method offers a facility to check the signature of a file with asymmetric cryptography.
void	sign(java.io.File input, java.io.File output, PrivateKey privateKey) This method offers a facility to sign files with asymmetric cryptography.

Method Detail

sign

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

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

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

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

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

Parameters:

signedFile - 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.
