Bug #8720
closedECB mode seems to be broken
Description
The reporting on this is partially from someone else's work that I found in a gist on github:
https://gist.github.com/tarcieri/5550786
But there appears to be some sort of issue with ECB mode. It works correctly in JRuby, which I assume is due to the fact that JRuby is using Java's underlying crypto libs instead of OpenSSL.
I've attached the test code from the gist. I've also included the output in the description here from my run with latest svn and the gist for reference:
