On my mac 10.5, when I use the OpenSSL :: Digest :: Digest.new ('sha256') command, I get the Unsupported digest algorithm (sha256). Does anyone know how to solve this?
OS X shipped with Ruby 1.8.6p287 doesn't seem to be compiled, but the one shipped with MacPorts has 1.8.7p160.
It is generally best to use the MacPorts version as it is more up to date.
