Currently, I'm doing my darndest to implement SSL file transfers. Using Net::SSH, I get "`initialize': Unsupported cipher algorithm (aes-128-cbc). (RuntimeError)" At first I thought this was a problem with the Net::SSH module, but it turns out that my SSL module seems to support no ciphers:
irb(main):004:0> c=OpenSSL::Cipher::Cipher.new("des-ede-cbc")
RuntimeError: Unsupported cipher algorithm (des-ede-cbc).
from (irb):4:in `initialize'
from (irb):4:in `new'
from (irb):4
···
from :0
I've tried this with multiple ciphers, to no avail.
Looking at the openssl/cipher.rb, it seems that a few classes are automatically made, but they don't work either:
irb(main):013:0> c=OpenSSL::Cipher::DES.new()
RuntimeError: Unsupported cipher algorithm (DES).
from (eval):5:in `initialize'
from (irb):13:in `new'
from (irb):13

I've searched high and low; the only remotely informative thing I found was in a thread in May of 2004. I used the example provided within ( c=OpenSSL::Cipher::Cipher.new("DES") ) and got the same problems.
Does anyone know what's going on here, and/or how to fix it?
A few more questions to see if we can narrow the scope of the problem:
1) What does the output of "openssl --help" tell you? There should be a section at the bottom of the output listing all available cipher commands. Are the ones you were requesting available?
2) Are you using a stock build of ruby, or a custom build?
3) What version of OpenSSL do you have installed?

Those ciphers lsited are what I tried first, with no luck. I'm using the Gentoo Ruby package ruby-1.8.2-r2; I'm not sure of the level of customization provided, however (sorry). I know for a fact that it was compiled with the ssl USE flag set, though.
Note: I just recompiled and tested ruby-1.8.2 (that is, not ruby-1.8.2-r2), and it doesn't work either.
