This method initializes signature verification or deletion procedure.

Declaration

[C#]
int OpenStream(System.IO.Stream Stream, bool OpenReadOnly /* = false */);

[VB.NET]
Function OpenStream(ByVal Stream As System.IO.Stream, ByVal OpenReadOnly As Boolean = False) As Integer

[Pascal]
function OpenStream(const Stream: TStream; OpenReadOnly: boolean = False): Integer;

[VB6]
not implemented;

[ActiveX]

[DLL]

Parameters

Stream - stream containing the executable which signature has to be verified or deleted
OpenReadOnly - Specifies whether the stream should be opened in read-only mode. This mode lets the executable open itself, however in this mode the signature can't be removed. Default value is False.

Return value

Error code

Values:

[Pascal] Value Description

SB_AUTHENTICODE_ERROR_SUCCESS 0 (0x0000)
OpenFile: File is opened successfully and further actions can be performed.
AddSignature: signature has been added successfully.
CloseFile: file was signed and closed succesfully. Next file can be signed.
VerifySignature: the verification was successful and the signature is correct. You should verify the certificate used for signing yourself.
RemoveAuthenticode: the signature was removed successfully. CloseFile method is called authomatically in this case.

SB_AUTHENTICODE_ERROR_UNKNOWN 9217 (0x2401) Any unforeseen error.

SB_AUTHENTICODE_ERROR_CANNOT_OPEN_FILE 9218 (0x2402)
OpenFile: File opening error. (File does not exists or it's impossible to open file in required mode.)

SB_AUTHENTICODE_ERROR_FILE_TOO_SMALL 9219 (0x2403)
OpenFile: File size is too small, so it is not correct EXE-file

SB_AUTHENTICODE_ERROR_CANNOT_READ_FILE 9220 (0x2404)
OpenFile: Error during file reading by any reason
RemoveAuthenticode: Error during file reading by any reason

SB_AUTHENTICODE_ERROR_CANNOT_WRITE_FILE 9221 (0x2405)
RemoveAuthenticode: Error during file writing by any reason

SB_AUTHENTICODE_ERROR_INVALID_EXECUTABLE 9222 (0x2406)
OpenFile: EXE-file is not correct. The execution file signature is corrupted.

SB_AUTHENTICODE_ERROR_INVALID_PE_FORMAT 9223 (0x2407)
OpenFile: The wrong format of the PE-file.

SB_AUTHENTICODE_ERROR_FILE_NOT_SIGNED 9224 (0x2408)
TElAuthenticodeVerifier.OpenFile: file is not signed
RemoveAuthenticode: file is not signed so nothing can be deleted

SB_AUTHENTICODE_ERROR_SIGNATURE_CORRUPTED 9225 (0x2409)
OpenFile: File signature is corrupted: either file is signed wrong or fields corresponding to the signature contain trash.
VerifySignature: the wrong signature format: it either does not contain information necessary for verification or this information is damaged

SB_AUTHENTICODE_ERROR_INVALID_ALGORITHM 9226 (0x240A)
AddSignature: certificate specifies unknown key algorithm
VerifySignature: signature specifies unknown or signature algorithm

SB_AUTHENTICODE_ERROR_INVALID_DIGEST_SIZE 9227 (0x240B)

SB_AUTHENTICODE_ERROR_INVALID_INDEX 9228 (0x240C)
VerifySignature: invalid index was passed

SB_AUTHENTICODE_ERROR_NO_SIGNER_CERTIFICATE 9229 (0x240D)
VerifySignature: certificate used for signature creation has not been found

SB_AUTHENTICODE_ERROR_INVALID_SIGNATURE 9230 (0x240E)
VerifySignature: the file was changed after signing

SB_AUTHENTICODE_ERROR_INVALID_CERTIFICATE 9231 (0x240F)
AddSignature: specified certificate does not contain private key.

SB_AUTHENTICODE_ERROR_FILE_ALREADY_SIGNED 9232 (0x2410)
TElAutehnticodeSigner.OpenFile: The file is already signed.

SB_AUTHENTICODE_ERROR_INVALID_ARGUMENT 9233 (0x2411)
AddSignature: signer's certificate is not specified.

SB_AUTHENTICODE_ERROR_INVALID_DATA 9234 (0x2412)
AddSignature: wrong order of methods calling. AddAuthenticode method has to be called first.
CloseFile: no data (AddAuthenticode method has not be called or returned error)

SB_AUTHENTICODE_ERROR_NO_SIGNATURES 9235 (0x2413)
CloseFile: no signatures (AddSignature method has not been called or returned error)

SB_AUTHENTICODE_ERROR_NO_COUNTERSIGNATURES 9236 (0x2414)

SB_AUTHENTICODE_ERROR_FILE_NOT_OPEN 9237 (0x2415)
RemoveAuthenticode: file is not open, OpenFile method was not called

SB_AUTHENTICODE_ERROR_SIGNATURE_NOT_LAST 9238 (0x2416)
RemoveAuthenticode: the signature is not last block of file so it can not be deleted

SB_AUTHENTICODE_ERROR_INVALID_AUTHENTICODE 9239 (0x2417)
VerifySignature: wrong authenticode

SB_AUTHENTICODE_ERROR_NO_TIMESTAMP 9240 (0x2418)
AddSignature: unable to get a timestamp while signing

Unit: SBAuthenticode

Description
