| virtual void ASN1Object::BEREncode | ( | BufferedTransformation & | bt | ) | const [inline, virtual, inherited] |
encode this object into a BufferedTransformation, using BER

| 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.

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