- This is a PSION series 3/3a verions of the S/Key One Time Password
- generator.
-
- I have changed the libaries extensively to remove calls to the
- clib. This makes the executable significantly smaller as the
- plib routines link into the Psion ROM. I have also removed the
- routines which convery the OTP pass-phrase back into a MD4 key;
- these wouldn't compile easily, as as they are not used it seemed
- a waste of my time to convert them.
-
- note: The series 3 has a 4.77Mhz processor compared to the 20Mhz
- processor in the 3a. As the MD4 alogrithm is computationaly
- expensive expect it to run slow on a 3!
-
- User Interface: Poor.
- Don't beat me up over this; the psion has an object
- orientated operating system. I had a four choices:
- restrict the password to less than 8 characters,
- display it when you type it in,
- replace methods
- or produce a text version.
-
- The first two are not very secure, I'm not yet up to speed on
- object orientated programming, so went for the last choice. If you
- want to give it a nice front-end, drop me a line, either to the work address
- below, or to my home address: richard@illuin.demon.co.uk
