SignedMap

public SignedMap(String signKey)

Creates a SignedMap

Parameters:

signKey - The name of the key whose value hosts the sign

Method Details

sign

public void sign(String secret)

Computes the sign based upon all the values of the map, and generates the sing inside the signKey

Parameters:

secret - The name of the shared secret that must be known to verify the validity of the map

verify

public boolean verify(String secret)

Computes the sign based upon all the values of the map except for the signKey and verifiy the it is the same of the signedKey

Parameters:

secret - The name of the shared secret that must be known to verify the validity of the map

Returns:

true if the sign is the same of the signedKey, false otherwise
