Member Function Documentation

◆ BERDecode()

void X509PublicKey::BERDecode ( BufferedTransformation bt)
virtual

Decode this object from a BufferedTransformation.

Parameters
btBufferedTransformation object

Uses Basic Encoding Rules (BER)

Implements ASN1Object.

Reimplemented in ed25519PublicKey, and InvertibleRSAFunction.

Definition at line 635 of file asn.cpp.

◆ DEREncode()

void X509PublicKey::DEREncode ( BufferedTransformation bt) const
virtual

Encode this object into a BufferedTransformation.

Parameters
btBufferedTransformation object

Uses Distinguished Encoding Rules (DER)

Implements ASN1Object.

Reimplemented in ed25519PublicKey, and InvertibleRSAFunction.

Definition at line 650 of file asn.cpp.

◆ GetAlgorithmID()

virtual OID X509PublicKey::GetAlgorithmID ( ) const
pure virtual

Retrieves the OID of the algorithm.

Returns
OID of the algorithm

Implemented in ed25519PublicKey, InvertibleRSAFunction, and RSAFunction.

◆ BERDecodeAlgorithmParameters()

virtual bool X509PublicKey::BERDecodeAlgorithmParameters ( BufferedTransformation bt)
inlinevirtual

Decode algorithm parameters.

Parameters
btBufferedTransformation 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
btBufferedTransformation 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
btBufferedTransformation object
parametersPresentflag indicating if algorithm parameters are present
sizenumber 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.

BERDecodeAlgorithmParameters

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

◆ DEREncodePublicKey()

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

Encode subjectPublicKey part of subjectPublicKeyInfo.

Parameters
btBufferedTransformation object

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

See also
DEREncodeAlgorithmParameters

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