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.

DEREncode()

void X509PublicKey::DEREncode ( BufferedTransformation &  bt ) const

virtual

Encode this object into a BufferedTransformation.

Parameters

bt	BufferedTransformation object

Uses Distinguished Encoding Rules (DER)

Implements ASN1Object.

GetAlgorithmID()

virtual OID X509PublicKey::GetAlgorithmID ( ) const

pure virtual

Retrieves the OID of the algorithm.

Returns

OID of the algorithm

Implemented in RSAFunction, InvertibleRSAFunction, and ed25519PublicKey.

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.

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

Definition at line 724 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.

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.
