Hi
I'm creating a password database (a dangerous thing to do, I know!) normally I'd hash the passwords for storage in the DB, but in this case I need to be able to also reverse them to their original state. I'm familiar with the digest module, but of course it isn't of use here. I didn't see anything obvious on my Google travels. Could anyone suggest how to perform encryption in ruby, in particular based on a rails application...?
Many thanks
Gabriel

Have a look here: Crypto in ruby - Stake Ventures (OpenSSL contains many encryption algorithms), and you might want to browse this list: http://raa.ruby-lang.org/cat.rhtml?category_major=Library;category_minor=Cryptography
Hope this helps,

You might want to check out keybox and see if it would meet your needs.
Its a pure ruby password database utilizing the SSL libraries for
encryption. It ships as a commandline application but it is fully
utilizable via its API.
If you have any questions, feel free to let me know.
enjoy,

Small nitpick about terminology: encryption is per definition 2 way,
what is often wrongly refered to as 1 way encryption is normally
cryptographic hashing (also see the note
http://en.wikipedia.org/wiki/One-way_encryption: "Note that encryption
is, by definition, reversible. Hence, the term one-way encryption is
slightly incorrect in a sense.")

Thank you very much, never thought of using the SSL library!
