TElX509CertificateEx.Verify method

TElX509CertificateEx.Verify

Verifies the signature of the data signed with the private key of this certificate

Declaration

[C#]
bool Verify(byte[] InBuffer, byte[] Signature);
bool Verify(byte[] InBuffer, int InStartIndex, int InCount, byte[] SigBuffer, int SigStartIndex, int SigCount);

[VB.NET]
Function Verify(ByVal InBuffer As Byte(), ByVal Signature As Byte()) As Boolean
Function Verify(ByVal InBuffer As Byte(), ByVal InStartIndex As Integer, ByVal InCount As Integer, ByVal SigBuffer As Byte(), ByVal SigStartIndex As Integer, ByVal SigCount As Integer) As Boolean

[Pascal]
function Verify( InBuffer : pointer; InSize : integer; Signature : pointer; SignatureSize : integer) : boolean;

[C++]
bool Verify(void * InBuffer, int32_t InSize, void * Signature, int32_t SignatureSize);

[Java]
boolean verify(byte[] InBuffer, int InStartIndex, int InCount, byte[] SigBuffer, int SigStartIndex, int SigCount);
boolean verify(byte[] InBuffer, byte[] Signature);

Parameters

InBuffer - should contain the data which should be verified
InSize - the size of InBuffer in bytes
Signature - buffer with digital signature
SignatureSize - the size of Signature in bytes
InStartIndex - the start position in the InBuffer from which the data must be read
InCount - number of bytes to be read
SigBuffer - buffer with digital signature
SigStartIndex - the start position in the SigBuffer from which the data must be read
SigCount - number of bytes in SigBuffer ti be read

Return value

True if the signature is successfully verified.
False otherwise.

Description

    This method causes TElX509Certificate object to validate the signature of data contained in InBuffer.
    it is a good idea not to trust the data whose signature is invalid.
     Note: If the signature includes certificates, they are used for verification instead of certificate, whose method is called. To avoid this, set IncludeCertificates parameter of Sign method to False.
