• OpenSSL::X509::Name#add_entry now accepts two additional keyword arguments 'loc' and 'set'. [GitHub #94]

Version 2.0.9

Security fixes

• OpenSSL::X509::Name#<=> could incorrectly return 0 (= equal) for non-equal objects. CVE-2018-16395 is assigned for this issue. https://hackerone.com/reports/387250

Bug fixes

• Fixed OpenSSL::PKey::*.{new,generate} immediately aborting if the thread is interrupted. [Bug #14882] [GitHub #205]

Bug fixes

• OpenSSL::Cipher#auth_data= could segfault if called against a non-AEAD cipher. [Bug #14024]
• OpenSSL::X509::Certificate#public_key= (and similar methods) could segfault when an instance of OpenSSL::PKey::PKey with no public key components is passed. [Bug #14087] [GitHub #168]

Version 2.0.6

Bug fixes

• The session_remove_cb set to an OpenSSL::SSL::SSLContext is no longer called during GC.

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]
• Broken length check in the PEM passphrase callback is fixed.
• It failed to compile when OpenSSL is configured without TLS 1.0 support.

Version 2.0.4

Bug fixes

• It now compiles with LibreSSL without renaming on Windows (mswin).
• A workaround for the error queue leak of X509_load_cert_crl_file() that causes random errors is added. [Bug #11033]

Version 2.0.3

Bug fixes

• A GC issue around OpenSSL::BN is fixed. [ruby/openssl#87]
• OpenSSL::ASN1 now parses BER encoding of GeneralizedTime without seconds. [ruby/openssl#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]

• Add support for LibreSSL

• OpenSSL::Cipher

  • OpenSSL::Cipher#key= and #iv= reject too long inputs. They used to truncate silently. [Bug #12561]

  • OpenSSL::Cipher#iv_len= is added. It allows changing IV (nonce) length if using AEAD ciphers. [Bug #8667], [Bug #10420], [GH ruby/ruby#569], [GH ruby/openssl#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]

  • OpenSSL::OCSP::Request and BasicResponse can be signed with non-SHA-1 hash algorithm. [Feature #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]

  • OpenSSL::PKey.read raises OpenSSL::PKey::PKeyError instead of ArgumentError for consistency with OpenSSL::PKey::{DH,DSA,RSA,EC}#new. [Bug #11774], [GH ruby/openssl#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]

  • 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]

  • 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]

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], [GH ruby/ruby#1196]

  • RC4 cipher suites are removed from OpenSSL::SSL::SSLContext::DEFAULT_PARAMS. RC4 is now considered to be weak. [GH ruby/openssl#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.
