openssl-ccm's Issues

Version 1.2.2

My current system is using lower case letters to =o

Any reasons why I should not publish the current master as version 1.2.2?

Unit tests no longer pass on OpenSSL 3.0

Hi there @SmallLars - thanks for the openssl-ccm Gem! 👍

It looks like OpenSSL 3.0 is out now, and the library/unit tests no longer work as expected with OpenSSL 3.0
https://github.com/ruby/openssl/blob/b31446464e1e9f8bd0c58e92f9e74a9c7663b0e0/History.md#version-300

With a fresh Ubuntu 22.04 machine, and the default Ruby 3.0 and OpenSSL 3.0 install the test suite fails:

Failure: test_aes_data(CCMTest)
/home/a/openssl-ccm/test/test_ccm.rb:294:in `block (5 levels) in test_aes_data'
     291:               output = o_file.read
     292:               ccm = OpenSSL::CCM.new(cipher, [key[j]].pack('H*'), mac_len[j])
     293:               c = ccm.encrypt(input, [nonce[j]].pack('H*'))
  => 294:               assert_equal(output.unpack('H*'), c.unpack('H*'),
     295:                            "Wrong ENCRYPT in Vector #{i + 1}")
     296:             end
     297:           end

With openssl 1.1.1n and libressl tests pass as expected:

6 tests, 203 assertions, 0 failures, 0 errors, 0 pendings, 0 omissions, 0 notifications
100% passed

I'm happy to help out where possible, let me know your thoughts 👍
