encrypt()
Encrypt the data using the RC4 (Rivest Cipher 4, also known as ARC4 or ARCFOUR) algorithm.
public encrypt(string $data,
string $key[,
string $mode
= ''
]) : string
RC4 is one of the standard encryption algorithm used in PDF format. If possible, please use AES encryption instead as this is insecure.
Parameters
