Member Function Documentation

template<class GP>

bool DL_PrivateKeyImpl< GP >::Validate	(	RandomNumberGenerator &	rng,
		unsigned int	level
	)		const

inlinevirtual

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

Implements CryptoMaterial.

Definition at line 756 of file pubkey.h.

template<class GP>

void DL_PrivateKeyImpl< GP >::AssignFrom ( const NameValuePairs & source )

inlinevirtual

assign values from source to this object

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

Implements CryptoMaterial.

Definition at line 774 of file pubkey.h.

template<class GP>

void DL_PrivateKeyImpl< GP >::GenerateRandom	(	RandomNumberGenerator &	rng,
		const NameValuePairs &	params
	)

inlinevirtual

generate a random key or crypto parameters

Exceptions

KeyingErr if algorithm parameters are invalid, or if a key can't be generated (e.g., if this is a public key object)

Reimplemented from GeneratableCryptoMaterial.

Definition at line 779 of file pubkey.h.

template<class GP>

bool DL_PrivateKeyImpl< GP >::SupportsPrecomputation ( ) const

inlinevirtual

Returns: whether this object supports precomputation

Reimplemented from CryptoMaterial.

Definition at line 790 of file pubkey.h.

template<class GP>

void DL_PrivateKeyImpl< GP >::Precompute ( unsigned int n = 16 )

inlinevirtual

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.

Definition at line 792 of file pubkey.h.

virtual void PKCS8PrivateKey::BERDecodeOptionalAttributes ( BufferedTransformation & bt )

virtualinherited

decode optional attributes including context-specific tag

/note default implementation stores attributes to be output in DEREncodeOptionalAttributes

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.

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)
