Hi,
please find here included a mail from Holger Klawitter, the author of one of
the mentioned palm cipher programs... He would have liked to recieve the
critique himself.

One of the major drawbacks of the Palm pilot is the maximum length
of a note which is 4096 bytes. ASCII Armouring makes text longer so
I decided to use an armour with 7bit significance. If the demand
proves to be more base 64 encoding I'll be happy to switch.

I think you've predicted my answer.
Side note to document what some people really (believe to) want:
I got some request for storing the passord in a database in order
not to have to type it in so often.
Of course, I denied the request :-)
Gru?
