Member Function Documentation

void ASN1CryptoMaterial::Load BufferedTransformation bt  )  [inline, virtual]
 

load key from a BufferedTransformation

Exceptions:
KeyingErr if decode fails
Note:
Generally does not check that the key is valid. Call ValidateKey() or ThrowIfInvalidKey() to check that.

Reimplemented from CryptoMaterial.

Definition at line 49 of file simple.h.

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

Definition at line 1551 of file cryptlib.h.

virtual void CryptoMaterial::AssignFrom const NameValuePairs source  )  [pure virtual, inherited]
 

assign values from source to this object

Note:
This function can be used to create a public key from a private key.

Implemented in DL_GroupParameters_EC< EC >, ESIGNFunction, InvertibleESIGNFunction, DL_GroupParameters_IntegerBased, DL_GroupParameters_IntegerBasedImpl< GROUP_PRECOMP, BASE_PRECOMP >, LUCFunction, InvertibleLUCFunction, RabinFunction, InvertibleRabinFunction, RSAFunction, InvertibleRSAFunction, RWFunction, InvertibleRWFunction, XTR_DH, DL_GroupParameters_IntegerBasedImpl< DL_GroupPrecomputation_LUC, DL_BasePrecomputation_LUC >, and DL_GroupParameters_IntegerBasedImpl< ModExpPrecomputation >.

virtual bool CryptoMaterial::Validate RandomNumberGenerator rng,
unsigned int  level
const [pure virtual, inherited]
 

check this object for errors

Parameters:
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
Returns:
true if the tests pass

Implemented in ESIGNFunction, InvertibleESIGNFunction, LUCFunction, InvertibleLUCFunction, DL_GroupParameters< T >, DL_PrivateKeyImpl< GP >, DL_PublicKeyImpl< GP >, RabinFunction, InvertibleRabinFunction, RSAFunction, InvertibleRSAFunction, RWFunction, InvertibleRWFunction, XTR_DH, DL_GroupParameters< Integer >, DL_GroupParameters< typename EcPrecomputation< EC >::Element >, DL_PrivateKeyImpl< DL_GroupParameters_EC< EC > >, and DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >.

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< typename EcPrecomputation< EC >::Element >, DL_PrivateKeyImpl< DL_GroupParameters_EC< EC > >, and DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >.

Definition at line 975 of file cryptlib.h.

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)

Definition at line 258 of file cryptlib.h.
