synopsys:

Cipher is a small application to keep your secrets really secret by
enciphering them with one of the most reliable encryption algorithms. 
The program can easily be installed on your Palm Pilot with
instapp.exe application (WinDOS) or with pilot-xfer (Unix) as any other
application. Download cipher11.zip. (Under UNIX, you sometimes need 
unzip -L to uncompress to get lowercase filenames.)
