## 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.
