Verifies a detached signature.

Syntax

• C++
• Objective-C
• C

ANSI (Cross Platform)
int VerifyDetached(const char* lpSignedData, int lenSignedData, const char* lpSignature, int lenSignature);

Unicode (Windows)
INT VerifyDetached(LPCSTR lpSignedData, INT lenSignedData, LPCSTR lpSignature, INT lenSignature);

- (void)verifyDetached:(NSData*)signedData :(NSData*)signature;

#define MID_PUBLICKEYCRYPTO_VERIFYDETACHED 13

SECUREBLACKBOXLITE_EXTERNAL int SECUREBLACKBOXLITE_CALL SecureBlackboxLite_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 message via the SignedData parameter, and the signature via the Signature parameter.

The validation result is stored in SignatureValidationResult property.

Provide the verification key in Key property before commencing verification.

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.)
