Some `require 'openssl'` statements were surrounded by `rescue` blocks to deal with Ruby versions that did not support `OpenSSL::Digest::SHA1` or `OpenSSL::PKCS5`.
[As @jeremy explains](a6a0904fcb (commitcomment-8826666)) in the original commit:
> If jruby didn't have jruby-openssl gem, the require wouldn't work. Not sure whether either of these are still relevant today.
According to the [release notes for JRuby 1.7.13](http://www.jruby.org/2014/06/24/jruby-1-7-13.html):
> jruby-openssl 0.9.5 bundled
which means the above `rescue` block is not needed anymore.
All the Ruby versions supported by the current version of Rails provide those OpenSSL libraries, so Travis CI should also be happy by removing the `rescue` blocks.

Just to confirm, with JRuby:
$ ruby --version #=> jruby 1.7.16.1 (1.9.3p392) 2014-10-28 4e93f31 on Java HotSpot(TM) 64-Bit Server VM 1.8.0_20-b26 +jit [darwin-x86_64]
$ irb
irb(main):001:0> require 'openssl' #=> true
irb(main):002:0> OpenSSL::Digest::SHA1 #=> OpenSSL::Digest::SHA1
irb(main):003:0> OpenSSL::PKCS5 # => OpenSSL::PKCS5
And with Ruby 2.1:
$ ruby --version #=> ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin13.0]
$ irb

irb(main):002:0> OpenSSL::Digest::SHA1 #=> OpenSSL::Digest::SHA1
irb(main):003:0> OpenSSL::PKCS5 #=> OpenSSL::PKCS5
This commit adds a `#verified` method to
`ActiveSupport::MessageVerifier` which will return either `false` when
it encounters an error or the message. `#verify` continues to raise an
`InvalidSignature` exception on error.
This commit also adds a convenience boolean method on `MessageVerifier`
as a way to check if a message is valid without performing the
decoding.
This broke natural order of things for `StaleSessionCheck#stale_session_check!` which tried auto_loading a class based on `ArgumentError` message , and later retrying the `Marshal#load` of class, successfully allowing auto_loading.
This PR tries to fix this behavior by forwarding `ArgumentError` 's not raised by `Base64.strict_decode64` , as is, ahead to `StaleSessionCheck#stale_session_check!`
By default, these classes use Marshal for serializing and deserializing messages. Unfortunately, the Marshal format is closely associated with Ruby internals and even changes between different interpreters. This makes the resulting message very hard to impossible to unserialize messages generated by these classes in other environments like node.js.
This patch solves this by allowing you to set your own custom serializer and deserializer lambda functions. By default, it still uses Marshal to be backwards compatible.
