ExportBytes Method
Exports the key to a byte array.
Syntax
ANSI (Cross Platform) char* ExportBytes(int iFormat, int iKeyType, int *lpSize = NULL); Unicode (Windows) LPSTR ExportBytes(INT iFormat, INT iKeyType, LPINT lpSize = NULL);
- (NSData*)exportBytes:(int)format :(int)keyType;
#define MID_CRYPTOKEYMANAGER_EXPORTBYTES 4 SECUREBLACKBOXLITE_EXTERNAL int SECUREBLACKBOXLITE_CALL SecureBlackboxLite_CryptoKeyManager_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);
Remarks
Use this method to save the Key (both the public and secret parts) to a byte array.
| kffUnknown | 0 | The key format was not recognized as one of the known formats. |
| kffAuto | 1 | The default format in current circumstances. This depends on the key being loaded or saved. |
| kffDER | 2 | DER (binary) format |
| kffPEM | 3 | PEM format (base64-encoded with headers) |
| kffJSON | 4 | JSON key format |
| ktAuto | 0 | The default key type in current circumstances. This depends on the operation, the file content, and the storage type. |
| ktPublic | 1 | The operation should be performed on a public key. |
| ktSecret | 2 | The operation should be performed on a private or secret key |
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.
