JRuby-OpenSSL
JRuby-OpenSSL is an add-on gem for JRuby that emulates the Ruby OpenSSL native library.
Under the hood it uses the Bouncy Castle Crypto APIs.
Each jruby-openssl gem release includes the Bouncy Castle library (BC Provider and PKIX/CMS/EAC/PKCS/OCSP/TSP/OPENSSL jars), usually the latest available version.
Please report bugs and incompatibilities (preferably with test-cases) to either the JRuby mailing list or the bug tracker.

Security
JRuby-OpenSSL is an essential part of JRuby, please report security vulnerabilities to
security@jruby.org as detailed on JRuby's security page or using GitHub.
Please note that most OpenSSL vulnerabilities do not affect JRuby since it's not using any of OpenSSL's C code, only Ruby parts (*.rb) are the same as in MRI's OpenSSL library.
Testing
rake jar:all # creates pom.xml and generates jopenssl.jar under lib
mvn test
This will run (JUnit as well as Ruby) tests against the default JRuby version. To pick a different JRuby version:
mvn test -Djruby.versions=9.4.14.0
For running integration tests the gem will be installed first and the same tests run for each supported Bouncy Castle version (see listing):
mvn verify -P test-9.4.14.0,test-9.2.21.0
Or pick a specific Bouncy Castle version:
mvn verify -P test-9.4.14.0 -Dbc.versions=1.78
NOTE: you can pick any JRuby version which is on Maven Central or on ci.jruby
