Member Function Documentation

template<class GP>

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

Implements CryptoMaterial.

template<class GP>

void DL_PublicKeyImpl< GP >::Precompute

(

unsigned int

precomputationStorage = 16

)

[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 from CryptoMaterial.

Definition at line 864 of file pubkey.h.

void ASN1CryptoMaterial< PublicKey >::Load

(

BufferedTransformation &

bt

)

[inline, virtual, inherited]

Reimplemented from CryptoMaterial.

Reimplemented in InvertibleRSAFunction.

Definition at line 240 of file asn.h.

References ASN1Object::BERDecode().

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
