ABSTRACT:
A pad encryption software architecture includes space on a floppy for storing the pad to be used with the encryption software. The pad is XOR generated with random numbers subject to redetermined offsets. If the pad is smaller than the text to be encrypted, then XOR takes several cycles with redetermined offsets used in XORing the pad with the remaining plain text to be encrypted. The offset is determined from a user selected password. New offsets are determined from old offsets by adding the current offset to the value of the byte in the pad located at the offset value.
