Constructor & Destructor Documentation

TX509DSAKeyEncoder(const CDSAPublicKey &, TAlgorithmId)

IMPORT_C	TX509DSAKeyEncoder	(	const CDSAPublicKey &	aKeyPublic,
			TAlgorithmId	aDigestAlg
		)

Constructs a DSA key pair encoder, saving reference to the passed public key in the member variable.

Parameters

const CDSAPublicKey & aKeyPublic	DSA public key to use for encoding.
TAlgorithmId aDigestAlg	Digest algorithm to use.

EncodeKeyLC()

IMPORT_C CASN1EncBase *

EncodeKeyLC

(

)

const [virtual]

Produces the SubjectPublicKeyInfo encoding.

The ASN.1 encoding of a DSA key has the following form:

 SEQUENCE-OF
     SEQUENCE-OF
         OID dsa (1.2.840.10040.4.1)
         SEQUENCE-OF
             INTEGER p
             INTEGER q
             INTEGER g
     BIT STRING
         INTEGER public value (y)

EncodeSignatureAlgorithmLC()

IMPORT_C CASN1EncSequence *

EncodeSignatureAlgorithmLC

(

)

const [virtual]

Produces the AlgorithmIdentifier encoding.

This has the following form:

 SEQUENCE-OF
     OID dsa-signature-oid
     SEQUENCE-OF dsa-params
         INTEGER p
         INTEGER q
         INTEGER g
