Method Details

verifyderived

public static boolean verifyderived(byte[] MasterSeed, Combine Signature, byte[] data, int Threshold, String Algorithm, int KEYBYTES, int BYTES) throws InvalidKeyException, NoSuchAlgorithmException

Verifies a signature of data against dynamically derived keys from a master seed

Parameters:

MasterSeed - - master seed in bytes of length KEYBYTES which the keys are derived from

Signature - - combined signature

data - - data which has been signed

Threshold - - minimum number of used keys

Algorithm - - algorithm used for HMAC

KEYBYTES - length of keys

BYTES - - length of signature

Returns:

verification of the signature (true/false)

Throws:

InvalidKeyException - - if the given key is inappropriate for initializing this HMAC

NoSuchAlgorithmException - - if the specified algorithm is not available
