void InvertibleRSAFunction::Load | ( | BufferedTransformation & | bt | ) | [inline, virtual] |
load key from a BufferedTransformation
KeyingErr | if decode fails |
Reimplemented from ASN1CryptoMaterial< PrivateKey >.
bool InvertibleRSAFunction::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 |
Implements CryptoMaterial.

Reimplemented from CryptoMaterial.
virtual void ASN1Object::BEREncode | ( | BufferedTransformation & | bt | ) | const [inline, virtual, inherited] |

virtual void CryptoMaterial::Precompute | ( | unsigned int | n | ) | [inline, virtual, inherited] |
do precomputation
The exact semantics of Precompute() is varies, but typically it means calculate a table of n objects that can be used later to speed up computation.

used to ensure we don't accidentally try to get an unsigned int or some other type when we mean int (which is the most common case)
