Twice.do

This is one of the four sample files provided for inspection and experimentation purposes. It contains "ciphertext" that is produced by double-encipherment by Keys 188 and 450.

OTPWC.do

This One-Time Pad encipherment/decipherment program is useful to owners of Model T laptop models: M100, M102, M200, KC85, and M10. OTP means One-Time Pad; OTPWC stands for "OTP Without Commentary"; file OTPWC.DO is the source of BASIC program OTPWC.BA. The famous OTP encryption method, also known as the Vernam cipher, has the highest security strength. Properly used, the OTP is a provably unbreakable cryptosystem. Use OTPWC.BA to apply OTP encipherment to your confidential "cleartext" information in order to render it as "ciphertext", which you then may transmit over non-secure channels (e.g., email message via the Internet) to your intended recipient(s) where the same program is used to apply OTP decipherment. Should such a message be intercepted by anyone other than your intended recipient(s) (i.e., folks who do not know the "key" or "keys" you selected during the OTP encipherment), any attempt at decipherment of your "ciphertext" message is so difficult as to be deemed impossible.

OTPIC.do

This One-Time Pad encipherment/decipherment program is useful to owners of Model T laptop models: M100, M102, M200, KC85, and M10.

Thrice.do

This is one of the four sample files provided for inspection and experimentation purposes. It contains "ciphertext" that is produced by triple-encipherment by Keys 188, 450, and 059.

Once.do

This is one of the four sample files provided for inspection and experimentation purposes. It contains "ciphertext" that is produced by single-encipherment by Key 188.

Orig.do

This is one of the four sample files provided for inspection and experimentation purposes. It contains a short sample of "cleartext" which is the origin for encipherment found in the other three sample files.
