getSignatureValid

public static boolean getSignatureValid(java.security.PublicKey publicKey,
                                        java.util.List<java.lang.String> values,
                                        java.lang.String signature)

Returns whether the signature for this license cache information is valid or not.

Parameters:

publicKey - the public key to use to verify the signature.

values - the list of values to verify.

signature - the signature to verify against.

Returns:

True if the signature is valid or false if not.

updateSignature

public static void updateSignature(java.security.Signature signatureObject,
                                   java.util.List<java.lang.String> values)
                            throws java.security.SignatureException

Updates a signature with a list of values.

Parameters:

signatureObject - the signature to update.

values - the list of values.

Throws:

java.security.SignatureException - if any problems were encountered updating the signature.

getSignature

public static java.lang.String getSignature(java.security.PrivateKey privateKey,
                                            java.util.List<java.lang.String> values)
                                     throws java.security.NoSuchAlgorithmException,
                                            java.security.InvalidKeyException,
                                            java.security.SignatureException

Gets a signature based on the private key and list of values.

Parameters:

privateKey - the private key.

values - the list of values.

Returns:

the signature.

Throws:

java.security.NoSuchAlgorithmException - if an algorithm couldn't be determined.
