Issue #8177 has been updated by Dvis Mosns. I'm still encountering similar issue with ruby 2.1.1p76 when using `OpenSSL::PKey::EC#sign`. Will it be fixed only in 2.2? Using the following monkey-patch it does work. ~~~ class OpenSSL::PKey::EC def private? private_key? end end ~~~ ---------------------------------------- Bug #8177: ext/openssl/pkcs7 signing fails with EC keys https://bugs.ruby-lang.org/issues/8177#change-45902 * Author: Joseph Coyle * Status: Assigned * Priority: Normal * Assignee: Martin Bosslet * Category: ext * Target version: current: 2.2.0 * ruby -v: ruby 2.1.0dev (2013-03-27 trunk 39950) [x86_64-darwin11.4.2] * Backport: ---------------------------------------- ext/openssl/pkcs7 signing fails with EC keys. This happens because the ECkeys do not respond to key.private? method which is used to check that thekey is a private key. Aliasing the instance method OpenSSL::PKey::EC.private_key? as OpenSSL::PKey::EC.private? fixes this problem and allows EC keys to be used for EC key signing. This problem is demonstrated at https://gist.github.com/Jacob640/5239454 One potential fix which makes the key interface more consistent is here: https://github.com/ruby/ruby/pull/265 This request also improves the EC public key interface by producing a warning if the public key is set before setting an EC group as required. ---Files-------------------------------- 265.patch (1.87 KB) -- https://bugs.ruby-lang.org/
