Member Function Documentation

◆ BERDecode()

void X509PublicKey::BERDecode ( BufferedTransformation & bt )

virtual

Decode this object from a BufferedTransformation.

Parameters

bt	BufferedTransformation object

Uses Basic Encoding Rules (BER)

Implements ASN1Object.

Definition at line 635 of file asn.cpp.

◆ BERDecodeAlgorithmParameters()

virtual bool X509PublicKey::BERDecodeAlgorithmParameters ( BufferedTransformation & bt )

inlinevirtual

Decode algorithm parameters.

Parameters

bt	BufferedTransformation object

See also: BERDecodePublicKey, RFC 2459, section 7.3.1

Definition at line 717 of file asn.h.

◆ BERDecodePublicKey()

virtual void X509PublicKey::BERDecodePublicKey	(	BufferedTransformation &	bt,
		bool	parametersPresent,
		size_t	size
	)

pure virtual

Decode subjectPublicKey part of subjectPublicKeyInfo.

Parameters

bt	BufferedTransformation object
parametersPresent	flag indicating if algorithm parameters are present
size	number of octets to read for the parameters, in bytes

BERDecodePublicKey() the decodes subjectPublicKey part of subjectPublicKeyInfo, without the BIT STRING header.

When parametersPresent = true then BERDecodePublicKey() calls BERDecodeAlgorithmParameters() to parse algorithm parameters.

See also: BERDecodeAlgorithmParameters

Implemented in RSAFunction, ed25519PublicKey, and DL_PublicKey_GFP< GP >.

◆ DEREncode()

Parameters

bt	BufferedTransformation object

Uses Distinguished Encoding Rules (DER)

Implements ASN1Object.

Definition at line 650 of file asn.cpp.

◆ DEREncodeAlgorithmParameters()

virtual bool X509PublicKey::DEREncodeAlgorithmParameters ( BufferedTransformation & bt ) const

inlinevirtual

Encode algorithm parameters.

Parameters

bt	BufferedTransformation object

See also: DEREncodePublicKey, RFC 2459, section 7.3.1

◆ DEREncodePublicKey()

virtual void X509PublicKey::DEREncodePublicKey ( BufferedTransformation & bt ) const

pure virtual

Encode subjectPublicKey part of subjectPublicKeyInfo.

Parameters

bt	BufferedTransformation object

DEREncodePublicKey() encodes the subjectPublicKey part of subjectPublicKeyInfo, without the BIT STRING header.

See also: DEREncodeAlgorithmParameters

Implemented in DL_PublicKey_GFP< GP >, RSAFunction, and ed25519PublicKey.

◆ GetAlgorithmID()

virtual OID X509PublicKey::GetAlgorithmID ( ) const
