  This article is meant to provide an additional point of view, applying known
knowledge, to supply keys that have a series of non-repeating digits, in a
manner that is not usually thought of. Traditionally, prime numbers are used in
encryption as keys that have non-repeating sequences. Non-repetition of digits
in a key is very sought after in encryption. Uniqueness in a digit sequence
defeats decryption by method. In searching for methods of non-decryptable
encryption as well as ways to provide unique sequences, other than using prime
numbers, the idea of using repeating decimals came to me. Applied correctly, a
repeating decimal series of sufficient length will stand in as well for a prime
number. This is so, because only numbers prime to each other will produce
repeating decimals and; within the repeating sequence there is uniqueness of
digit sequence.
