Issue #5233 has been updated by Martin Bosslet. Also thanks to Eric, for providing his thoughts on the topic! ---------------------------------------- Bug #5233: OpenSSL::SSL::SSLSocket has problems with encodings other than "ascii" http://redmine.ruby-lang.org/issues/5233 Author: Niklas Baumstark Status: Closed Priority: Normal Assignee: Martin Bosslet Category: ext Target version: 1.9.4 ruby -v: ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux] The attached script shows the issue. It expects a combined cert/private key in the file server.pem under the current directory (also attached). Under Ruby 1.9.2p290, the script prints "str.size is 50848 (expecting 100000)". As a workaround the string encoding can be forced to "ascii" before the write. -- http://redmine.ruby-lang.org
