[RPN] password store Message #1 Posted by jerome ibanes on 29 Jan 2013, 2:01 p.m.
Hello,
I own a few RPN calculators (HP-15c, HP-16c, WP-34s, HP-42s) and I was wondering if I could use one of them to store passwords for the few (maybe 25~) login credentials that are required for work or internet in general. Some passwords are as long as 20 characters.
While I own a few RPL calculators (various generations of the HP-48, HP-49, HP-50), I think those are too big to carry on a daily basis, while the RPN ones are easy to carry in a pocket, making it the ideal companion for data storage.
The volume of data is about 25 passwords, times 20 characters and a 8 character description per password, hence 25*20*8 = 4KB. Due to the unfrequent updates, those could be stored in firmware, in the case of the WP-34s, but this isn't a strong requirement.
This password store would have to be protected by a password or combination of keys; their encryption would be nice, but isn't a strong requirement.
Let me know if this has been done or if this is even doable.
Thank you,
Jerome
