Member Function Documentation

virtual void ASN1Object::BEREncode ( BufferedTransformation bt) const
inlinevirtualinherited

encode this object into a BufferedTransformation, using BER

this may be useful if DEREncode() would be too inefficient

Definition at line 1643 of file cryptlib.h.

virtual void CryptoMaterial::AssignFrom ( const NameValuePairs source)
pure virtualinherited
virtual bool CryptoMaterial::Validate ( RandomNumberGenerator rng,
unsigned int  level 
) const
pure virtualinherited

check this object for errors

Parameters
leveldenotes 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

virtual bool CryptoMaterial::SupportsPrecomputation ( ) const
inlinevirtualinherited
virtual void CryptoMaterial::Precompute ( unsigned int  n)
inlinevirtualinherited

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 in DL_PublicKeyImpl< GP >, DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >, DL_PrivateKeyImpl< GP >, DL_PrivateKeyImpl< DL_GroupParameters_EC< EC > >, DL_GroupParameters< T >, and DL_GroupParameters< Integer >.

Definition at line 1080 of file cryptlib.h.

bool NameValuePairs::GetIntValue ( const char *  name,
int &  value 
) const
inlineinherited

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)
