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/Cipher.html

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

thanks
nick
