ENCRYPT version 3.0 by D. Whitman

Syntax:  ENCRYPT [?] [/key] [<infile] [>outfile]

Reads stdin, encrypts data, and writes it to stdout.
If file is already encrypted, it will be decrypted.

An optional "key" word can be specified.
If used, the key must also be specified when decrypting the file.

The ? option prints this help message.

Encrypted text is unintelligable, and cannot be decoded by simple
substitution.  However, the encryption algorithm is by no means unbreakable.
Encryption should not be used as a replacement for proper security
with extremely sensitive data.

Warning: editing of encrypted files can scramble them beyond recovery!
