  Detailed description  
This class can be used to encrypt and decrypt data with one time pad cipher algorithm implemented in pure PHP.

The class has a single function that takes a password and a string of the data to encrypt.

The password is used to create a cypher that encrypts the data using an XOR operation.

The same function to encrypt can be used to decrypt the encrypted data using the same password.

 The quality of encryption algorithms depends on how hard they are to break using brute force methods.

Most strong encryption methods also take a lot of CPU resources to encrypt and decrypt data.

One time pad algorithms are much simpler and take less resources when used to encrypt and decrypt data.

This class implements a one-time pad algorithm in pure PHP code. It generates several hashes of the encryption password to compute a random cypher that is used to encrypt and decrypt data.

The actual encryption and decryption is very light because it consists of a simple XOR operation over the data to encrypt or decrypt. The encryption and encryption procedure is the same, making the class very small.
