ChangeProtection Method
Changes the protection level of the secret key.
Syntax
int ChangeProtection(const QString& qsOldPassphrase, const QString& qsNewPassphrase, int iProtType, const QString& qsEncAlgorithm, const QString& qsHashAlgorithm);
Remarks
Use this method to change the protection level of the Key.
OldPassphrase specifies the current password to decrypt the key, NewPassphrase is the new password for the key, ProtType is the new protection type (see for more details), EncAlgorithm is the key encryption algorithm, and

Error Handling
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.)
