[[GitHub #94]](https://github.com/ruby/openssl/issues/94)
* OpenSSL::SSL::SSLContext#min_version= and #max_version= are added to replace
#ssl_version= that was built on top of the deprecated OpenSSL C API. Use of
that method and the constant OpenSSL::SSL::SSLContext::METHODS is now
deprecated.

[[Bug #14024]](https://bugs.ruby-lang.org/issues/14024)

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.
