encryption using ruby?

Hi all

I need to be able to encrypt/decrypt a small text file, but I'm struggling a
little finding an encryption library.

I found Jamis Buck's previous post about using openssl for encryption and
whilst it works, I can't make head nor tails of the openssl docs at
ruby-docs.org. I can't find any of the methods Jamis used in his code...
there only seem to be two of them for the cipher module.. ?
http://www.ruby-doc.org/stdlib/libdoc/openssl/rdoc/classes/OpenSSL/Cipher/C...

can anyone explain how the openssl library should be used please?

thanks
nick

See

http://ruby-talk.org/cgi-bin/scat.rb/ruby/ruby-t...

for a pure-Ruby encryption lib.

It took me some time to figure it out myself. Ive got a small wrapper
library that I use to simplify my life. When I get home I will post a
blog entry with it and how it works.

For my new project https://stak... (blatant plug alert), I am
doing alot of crypto using the OpenSSL libraries.

I will submit most of this and my encrypting ActiveRecord wrapper to
rails in a few weeks time, when I have time to clean it up a bit.

Just posted a really quick small example of doing AES encryption using openssl :
