TElDSAPublicKeyCrypto.DecodeSignature method

TElDSAPublicKeyCrypto.DecodeSignature

Decodes a DSA signature blob into "R" and "S" parameters.

Declaration

[C#]
void DecodeSignature(byte[] Sig, int SigIndex, int SigSize, ref byte[] R, int RIndex, ref int RSize, ref byte[] S, int SIndex, ref int SSize);

[VB.NET]
Sub DecodeSignature(ByVal Sig As Byte(), ByVal SigIndex As Integer, ByVal SigSize As Integer, ByRef R As Byte(), ByVal RIndex As Integer, ByRef RSize As Integer, ByRef S As Byte(), ByVal SIndex As Integer, ByRef SSize As Integer)

[Pascal]
procedure DecodeSignature(Sig : pointer; SigSize : integer; R : pointer; var RSize : integer; S : pointer; var SSize : pointer);

[C++]
void DecodeSignature(void * Sig, int32_t SigSize, void * R, int32_t &RSize, void * S, int32_t &SSize);

[Java]
void decodeSignature(byte[] Sig, int SigIndex, int SigSize, byte[][] R, int RIndex, int[] RSize, byte[][] S, int SIndex, int[] SSize);

Parameters

Sig - encoded signature
SigSize - size of the Sig buffer
SigIndex - index from which the signature data begins in the Sig buffer
R - DSA "R" parameter
RSize - size of the R buffer
RIndex - index from which the "R" data begins in the R buffer
S - DSA "S" parameter
SSize - size of the S buffer
SIndex - index from which the "S" data begins in the S buffer

Description

Use this method to decode a DSA signature blob and extract the "R" and "S" DSA parameters.
