How can I encrypt a file in AES's EAX mode?

Question

Is there a Python library which supports AES EAX mode? PyCrypto doesn't seem to support it.

Is there a reason why it doesn't seem to be supported?

Answer 1

EAX (and others AEAD modes like GCM, CCM and SIV) will be soon supported in version 2.7 of PyCrypto.

Right now, on the PyCrypto website there is an alpha version available for download. Alternatively, you can check out the current master branch on github.

Answer 2

I would recommend that you take a look at this LibTomCrypt wrapper. It should support what you need.
