And you are posting this to Ruby-lang why? Sounds like you didn't even try
to contact the author of EzCrypto.

http://ezcrypto.rubyforge.org/

And too bad, I'm going to tell you to RTFM. I checked it out (I have no
prior knowledge of this library) and I think I already know what's wrong
with your code:

Key#new:
"Initialize the key with raw unencoded binary key data. This needs to be at
least 16 bytes long for the default aes-128 algorithm."

It wants "raw binary key data". A Ruby string is not "raw binary key data".

Otherwise, I was unable to get it working with blowfish or aes-128-cbc, so
either go get a hold of the author and ask, try to fix the problem yourself,
or assume that the library is broken (it was released in Sept 2006) and move
on.
