This function either encrypts or decrypts the file - *file_path*.
Encryption or decryption depends upon the file's extension.
The user's encryption or decryption task is almost automated since
*encryption* or *decryption* is determined by the file's extension.
Added:
After the *file_path* decryption, decrypted file's verification
is done. If it fails, either the Password is incorrect or the
encrypted data was supposedly tampered with.
Usage
