TElPublicKeyCrypto.Verify method

TElPublicKeyCrypto.Verify

This method verifies digitally signed data

Declaration

[C#]
TSBPublicKeyVerificationResult Verify(byte[] InBuffer, int InIndex, int InSize, ref byte[] OutBuffer, int OutIndex, ref int OutSize);
TSBPublicKeyVerificationResult Verify(System.IO.Stream InStream, System.IO.Stream OutStream, int Count);

[VB.NET]
Function Verify(ByVal InBuffer As Byte(), ByVal InIndex As Integer, ByVal InSize As Integer, ByRef OutBuffer As Byte(), ByVal OutIndex As Integer, ByRef OutSize As Integer) As TSBPublicKeyVerificationResult
Function Verify(ByVal InStream As System.IO.Stream, ByVal OutStream As System.IO.Stream, ByVal Count As Integer) As TSBPublicKeyVerificationResult

[Pascal]
function Verify(InBuffer: pointer; InSize: integer; OutBuffer: pointer; var OutSize: integer): TSBPublicKeyVerificationResult;
function Verify(InStream, OutStream : TStream; Count : integer = 0): TSBPublicKeyVerificationResult;

[Java]
TSBPublicKeyVerificationResult verify(InputStream InStream, OutputStream OutStream, int Count);
TElPublicKeySyncVerificationResult verify(byte[] InBuffer, int InIndex, int InSize, byte[] OutBuffer, int OutIndex, int OutSize);

Parameters

InBuffer - data buffer to verify
InIndex - offset of actual data from the beginning of the array
InSize - size of input data in bytes
OutBuffer - buffer where to put verified data
OutIndex - output buffer start offset
OutSize - the maximal expected size of output data in bytes
InStream - the stream with data to verify.
OutStream - the stream for verified data.
Count - the number of bytes to be read. If this parameter is zero, the whole stream is processed.
Default value is 0.

Return value

Verification result

Possible values:

[.NET] [C++]	[Pascal]	Description
pkvrSuccess = 0	pkvrSuccess	The verification operation was successful (i.e., the signature is valid)
pkvrInvalidSignature = 1	pkvrInvalidSignature	Verification failed, the signature is not valid or the document was corrupted
pkvrKeyNotFound = 2	pkvrKeyNotFound	Verification failed, because the key was not found
pkvrFailure = 3	pkvrFailure	General failure

Description

Use this method to verify the chunk of data with a key specified by the KeyMaterial property.
