ABSTRACT:
In symmetric methods of encryption the key should be as long as the plaintext message. Such a key is difficult to generate if the plaintext data to be encrypted is enormous. The present invention provides a method of creating a random key of variable length which may be extremely long. It is generated by consecutively applying sub-keys having shorter non-repeating random lengths.
