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 |

| void RWFunction::AssignFrom | ( | const NameValuePairs & | source | ) | [virtual] |

Implements CryptoMaterial.

| virtual void CryptoMaterial::Load | ( | BufferedTransformation & | bt | ) | [inline, virtual, inherited] |
load key from a BufferedTransformation
| KeyingErr | if decode fails |
Reimplemented in InvertibleRSAFunction, ASN1CryptoMaterial< PrivateKey >, ASN1CryptoMaterial< DL_GroupParameters< Integer > >, and ASN1CryptoMaterial< PublicKey >.

| 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.
Reimplemented in DL_GroupParameters< T >, DL_PrivateKeyImpl< GP >, DL_PublicKeyImpl< GP >, DL_GroupParameters< Integer >, DL_GroupParameters< typenameEcPrecomputation< EC >::Element >, DL_PrivateKeyImpl< DL_GroupParameters_EC< EC > >, and DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >.

| 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)
