bool DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >::Validate | ( | RandomNumberGenerator & | rng, | |
unsigned int | level | |||
) | const [inline, virtual, inherited] |
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.
bool DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >::SupportsPrecomputation | ( | ) | const [inline, virtual, inherited] |
Reimplemented from CryptoMaterial.
void DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >::Precompute | ( | unsigned int | n = 16 |
) | [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.
Reimplemented from CryptoMaterial.
void ASN1CryptoMaterial< PublicKey >::Load | ( | BufferedTransformation & | bt | ) | [inline, virtual, inherited] |
Reimplemented from CryptoMaterial.
Reimplemented in InvertibleRSAFunction.
virtual void ASN1Object::BEREncode | ( | BufferedTransformation & | bt | ) | const [inline, virtual, inherited] |
encode this object into a BufferedTransformation, using BER
this may be useful if DEREncode() would be too inefficient

CRYPTOPP_DLL bool NameValuePairs::GetIntValue | ( | const char * | name, | |
int & | value | |||
) | const [inline, inherited] |
get a named value with type int
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)
