Verifies a detached signature.

Syntax

• C++
• Objective-C
• C

ANSI (Cross Platform)
int VerifyDetachedFile(const char* lpszSignedDataFile, const char* lpszSignatureFile);

Unicode (Windows)
INT VerifyDetachedFile(LPCWSTR lpszSignedDataFile, LPCWSTR lpszSignatureFile);

- (void)verifyDetachedFile:(NSString*)signedDataFile :(NSString*)signatureFile;

#define MID_PUBLICKEYCRYPTO_VERIFYDETACHEDFILE 14

SECUREBLACKBOX_EXTERNAL int SECUREBLACKBOX_CALL SecureBlackbox_PublicKeyCrypto_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

Use this method to verify a detached signature. Pass the original data via the SignedDataFile parameter, and the signature via the SignatureFileparameter.

The validation result is stored in SignatureValidationResult property.

Provide the verification key in Key property.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
