bool InvertibleRWFunction::Validate | ( | RandomNumberGenerator & | rng, | |
unsigned int | level | |||
) | const [virtual] |
check this object for errors
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 |
