[MacRuby] #215: OpenSSL's SSLSocket appears not to be initialised correctly

#215: OpenSSL's SSLSocket appears not to be initialised correctly -------------------------------+-------------------------------------------- Reporter: celtic@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: openssl -------------------------------+-------------------------------------------- When using net/https, the line to create the new SSLSocket in `connect' fails in OpenSSL::SSL::Nonblock, trying to call @io.fcntl and failing since @io==nil. @io should be being set in OpenSSL's ossl_ssl.c:ossl_ssl_initialize; "ossl_ssl_set_io(self, io)"; but this function appears never to be called! (I tried inserting various rb_warns throughout, before finally just sticking in a call to exit() -- it's not being touched) This appears to be the only place where @io is being set. It disturbs me that the C initialiser is not being run - I am not sure if this is a documented issue or not, or if it's even a MacRuby bug (I'm quite new to all this). This problem can be 'fixed' in the meantime by rewriting SSLSocket#initialize in Ruby-land: {{{ def initialize io, ctx=nil ctx = SSLContext.new if ctx.nil? raise "wrong argument (#{ctx.class})! (Expected kind of SSLContext)" if not ctx.kind_of? SSLContext raise "wrong argument (#{io.class})! (Expected kind of IO)" if not io.kind_of? IO @io, @ctx = io, ctx @sync_close = false @ctx.setup super end }}} ossl_ssl_initialize can be removed from ossl_ssl.c after this. Unfortunately, we just run into another bug in ossl_ssl_setup, which has to do with an SSLContext, trying to work out if it's related now. -- Ticket URL: <http://www.macruby.org/trac/ticket/215> MacRuby <http://macruby.org/>

[macruby] #104: Problem with OpenSSL using MacRuby's internal conversion to and from NSData

#104: Problem with OpenSSL using MacRuby's internal conversion to and from NSData --------------------------------+------------------------------------------- Reporter: rich(a)infoether.com | Owner: lsansonetti(a)apple.com Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: --------------------------------+------------------------------------------- This code will reproduce the problem: require 'openssl' require 'digest/sha1' CRYPT = "aes256" password = 'test' gen_key = OpenSSL::Cipher::Cipher.new(CRYPT) gen_key.encrypt key_crypt = OpenSSL::Cipher::Cipher.new(CRYPT) key_crypt.encrypt key_crypt.key = Digest::SHA1.hexdigest(password+CRYPT)[2,32] key = key_crypt.update("KEY_"+OpenSSL::Random.random_bytes(key_crypt.key_len)) key << key_crypt.final #comment out next line and it works File.open("tmp.key", "wb") {|f| f.write(key)} key_decrypt = OpenSSL::Cipher::Cipher.new(CRYPT) key_decrypt.decrypt key_decrypt.key = Digest::SHA1.hexdigest(password+CRYPT)[2,32] db_key = key_decrypt.update(key) db_key << key_decrypt.final If you take out that file write operation, then this code will run. You leave it in and you get block_length error. I believe that has to do with internally converting objects to NSData when treated as binary. It still says the class is NSCFString but something is happening to it. -- Ticket URL: <https://www.macruby.org/trac/ticket/104> macruby <http://macruby.org/>
