      @tqbf @_emboss_ @matthew_d_greeen if the data you're trying to encrypt is an exact match of the block size, you don't get a padding block

      @bascule @_emboss_ @matthew_d_greeen Isn't that why you'd use CTR?

      @tqbf @bascule There was a time way back (couple of months) where certain libs didn't offer CTR yet by default ;)

      @_emboss_ @bascule I still don't think there's an easy way to get it in Ruby; you gotta build it on ECB.

      @tqbf it's pretty much the #1 thing I'd like to see @_emboss_ fix with krypt

      @bascule @_emboss_ Best thing ever would be an AEAD mode, preferably the default.

      @tqbf @bascule True. We'll soon support it with OpenSSL at least, there's a patch lying around that I need to apply.

      Replying to @_emboss_

      @_emboss_ @tqbf seems like Krypt could use the OpenSSL provider if it has CTR, if not fall back on a pure Ruby version

      @bascule @tqbf That would be the plan, but I have to wrap my head around how I can get bit-level stuff fast enough in Ruby.

      @_emboss_ @tqbf yeah that's the problem with the pure Ruby version... it's comparatively slow :(

          @bascule ..and switching to native too often is also not great, because of massive duplication of C/Java code. I'll work it out. Somehow ;)
