Verify Method

Verifies an enveloped or enveloping signature contained in a buffer.

Syntax

• C++
• Objective-C
• C

ANSI (Cross Platform)
char* Verify(const char* lpBuffer, int lenBuffer, int *lpSize = NULL);

Unicode (Windows)
LPSTR Verify(LPCSTR lpBuffer, INT lenBuffer, LPINT lpSize = NULL);

- (NSData*)verify:(NSData*)buffer;

#define MID_PUBLICKEYCRYPTO_VERIFY 12

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 an enveloped or enveloping signature contained in a byte array.The method verifies the signature and extracts the original signed content intoanother byte array.

The validation result is stored in SignatureValidationResult property.

Use VerifyDetached to verify detached signatures.

Specify the verification key in the Key property before commencing verification.

Error Handling (C++)

This method returns a Byte Array value (with length lpSize); after it returns, call the GetLastErrorCode() method to obtain its 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.
