Issue #6252 has been reported by sacketty (Henri Sack). ---------------------------------------- Bug #6252: OpenSSL - ECDSA signature reliability https://bugs.ruby-lang.org/issues/6252 Author: sacketty (Henri Sack) Status: Open Priority: Normal Assignee: MartinBosslet (Martin Bosslet) Category: lib Target version: 1.9.3 ruby -v: ruby 1.9.3p125 (2012-02-16 revision 34643) [i686-linux] =begin The snippet code attached shows ECDSA signature test with secp160r1 curve. Given: * ((|msg|)) a message with length <= 20, * ((|sig|)) the ECDSA signature of ((|msg|)) * ((|tamp|)), a string, Then ((|sig|)) can be successfully used to verify any message in the form ((|msg|)) + ((|tamp|)) =end -- http://bugs.ruby-lang.org/
