Member Function Documentation

bool RabinFunction::Validate	(	RandomNumberGenerator &	rng,
		unsigned int	level
	)			const [virtual]

check this object for errors

Parameters:

level

denotes the level of thoroughness: 0 - using this object won't cause a crash or exception (rng is ignored) 1 - this object will probably function (encrypt, sign, etc.) correctly (but may not check for weak keys and such) 2 - make sure this object will function correctly, and do reasonable security checks 3 - do checks that may take a long time

Returns:

true if the tests pass

Implements CryptoMaterial.

Reimplemented in InvertibleRabinFunction.

void RabinFunction::AssignFrom

(

const NameValuePairs &

source

)

[virtual]

assign values from source to this object

Note:

This function can be used to create a public key from a private key.
