    		 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.

  • 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.
