[[GitHub #153]](https://github.com/ruby/openssl/pull/153) * Possible deadlock is fixed. This happened only when built with older versions of OpenSSL (before 1.1.0) or LibreSSL. [[GitHub #155]](https://github.com/ruby/openssl/pull/155) Version 2.0.5 ============= Bug fixes --------- * Reading a PEM/DER-encoded private key or certificate from an IO object did not work properly on mswin platforms. [[ruby/openssl#128]](https://github.com/ruby/openssl/issues/128) * Broken length check in the PEM passphrase callback is fixed. * It failed to compile when OpenSSL is configured without TLS 1.0 support.

[[ruby/openssl#88]](https://github.com/ruby/openssl/pull/88) Version 2.0.0 ============= This is the first release of openssl gem, formerly a standard library of Ruby, ext/openssl. This is the successor of the version included in Ruby 2.3. Compatibility notes ------------------- * Support for OpenSSL version 0.9.6 and 0.9.7 is completely removed. openssl gem still works with OpenSSL 0.9.8, but users are strongly encouraged to upgrade to at least 1.0.1, as OpenSSL < 1.0.1 will not receive any security fixes from the OpenSSL development team. Supported platforms ------------------- * OpenSSL 1.0.0, 1.0.1, 1.0.2, 1.1.0 * OpenSSL < 0.9.8 is no longer supported. * LibreSSL 2.3, 2.4, 2.5 * Ruby 2.3, 2.4 Notable changes --------------- * Add support for OpenSSL 1.1.0. [[Feature #12324]](https://bugs.ruby-lang.org/issues/12324) * Add support for LibreSSL * OpenSSL::Cipher - OpenSSL::Cipher#key= and #iv= reject too long inputs. They used to truncate silently. [[Bug #12561]](https://bugs.ruby-lang.org/issues/12561) - OpenSSL::Cipher#iv_len= is added. It allows changing IV (nonce) length if using AEAD ciphers. [[Bug #8667]](https://bugs.ruby-lang.org/issues/8667), [[Bug #10420]](https://bugs.ruby-lang.org/issues/10420), [[GH ruby/ruby#569]](https://github.com/ruby/ruby/pull/569), [[GH ruby/openssl#58]](https://github.com/ruby/openssl/pull/58) - OpenSSL::Cipher#auth_tag_len= is added. This sets the authentication tag length to be generated by an AEAD cipher. * OpenSSL::OCSP - Accessor methods are added to OpenSSL::OCSP::CertificateId. [[Feature #7181]](https://bugs.ruby-lang.org/issues/7181) - OpenSSL::OCSP::Request and BasicResponse can be signed with non-SHA-1 hash algorithm. [[Feature #11552]](https://bugs.ruby-lang.org/issues/11552) - OpenSSL::OCSP::CertificateId and BasicResponse can be encoded into DER. - A new class OpenSSL::OCSP::SingleResponse is added for convenience. - OpenSSL::OCSP::BasicResponse#add_status accepts absolute times. They used to accept only relative seconds from the current time. * OpenSSL::PKey - OpenSSL::PKey::EC follows the general PKey interface. [[Bug #6567]](https://bugs.ruby-lang.org/issues/6567) - OpenSSL::PKey.read raises OpenSSL::PKey::PKeyError instead of ArgumentError for consistency with OpenSSL::PKey::{DH,DSA,RSA,EC}#new. [[Bug #11774]](https://bugs.ruby-lang.org/issues/11774), [[GH ruby/openssl#55]](https://github.com/ruby/openssl/pull/55) - OpenSSL::PKey::EC::Group retrieved by OpenSSL::PKey::EC#group is no longer linked with the EC key. Modifications to the EC::Group have no effect on the key. [[GH ruby/openssl#71]](https://github.com/ruby/openssl/pull/71) - OpenSSL::PKey::EC::Point#to_bn allows specifying the point conversion form by the optional argument. * OpenSSL::SSL - OpenSSL::SSL::SSLSocket#tmp_key is added. A client can call it after the connection is established to retrieve the ephemeral key. [[GH ruby/ruby#1318]](https://github.com/ruby/ruby/pull/1318) - The automatic ephemeral ECDH curve selection is enabled by default when built with OpenSSL >= 1.0.2 or LibreSSL. - OpenSSL::SSL::SSLContext#security_level= is added. You can set the "security level" of the SSL context. This is effective only when built with OpenSSL 1.1.0. - A new option 'verify_hostname' is added to OpenSSL::SSL::SSLContext. When it is enabled, and the SNI hostname is also set, the hostname verification on the server certificate is automatically performed. It is now enabled by OpenSSL::SSL::SSLContext#set_params. [[GH ruby/openssl#60]](https://github.com/ruby/openssl/pull/60) Removals -------- * OpenSSL::Engine - OpenSSL::Engine.cleanup does nothing when built with OpenSSL 1.1.0. * OpenSSL::SSL - OpenSSL::PKey::DH::DEFAULT_512 is removed. Hence servers no longer use 512-bit DH group by default. It is considered too weak nowadays. [[Bug #11968]](https://bugs.ruby-lang.org/issues/11968), [[GH ruby/ruby#1196]](https://github.com/ruby/ruby/pull/1196) - RC4 cipher suites are removed from OpenSSL::SSL::SSLContext::DEFAULT_PARAMS. RC4 is now considered to be weak. [[GH ruby/openssl#50]](https://github.com/ruby/openssl/pull/50) Deprecations ------------ * OpenSSL::PKey - OpenSSL::PKey::RSA#n=, #e=, #d=, #p=, #q=, #dmp1=, #dmq1=, #iqmp=, OpenSSL::PKey::DSA#p=, #q=, #g=, #priv_key=, #pub_key=, OpenSSL::PKey::DH#p=, #g=, #priv_key= and #pub_key= are deprecated. They are disabled when built with OpenSSL 1.1.0, due to its API change. Instead, OpenSSL::PKey::RSA#set_key, #set_factors, #set_crt_params, OpenSSL::PKey::DSA#set_pqg, #set_key, OpenSSL::PKey::DH#set_pqg and #set_key are added. * OpenSSL::Random - OpenSSL::Random.pseudo_bytes is deprecated, and not defined when built with OpenSSL 1.1.0. Use OpenSSL::Random.random_bytes instead. * OpenSSL::SSL - OpenSSL::SSL::SSLContext#tmp_ecdh_callback is deprecated, as the underlying API SSL_CTX_set_tmp_ecdh_callback() is removed in OpenSSL 1.1.0. It was first added in Ruby 2.3.0. To specify the curve to be used in ephemeral ECDH, use OpenSSL::SSL::SSLContext#ecdh_curves=. The automatic curve selection is also now enabled by default when built with a capable OpenSSL.
