title: Which AES library to use in Ruby/Python?
body: <p>I need to be able to send encrypted data between a Ruby client and a Python server (and vice versa) and have been having trouble with the <a href="http://rubyforge.org/projects/ruby-aes" rel="nofollow noreferrer">ruby-aes</a> gem/library. The library is very easy to use but we've been having trouble passing data between it and the pyCrypto AES library for Python. These libraries seem to be fine when they're the only one being used, but they don't seem to play well across language boundaries. Any ideas?</p>
  
  <p>Edit: We're doing the communication over SOAP and have also tried converting the binary data to base64 to no avail. Also, it's more that the encryption/decryption is almost but not exactly the same between the two (e.g., the lengths differ by one or there is extra garbage characters on the end of the decrypted string)</p>
