Easy Python Cryptography
Via Garth Kidd’s Python cryptography roundup, ezPyCrypto is a cryptography API so simple even I can use it. Unfortunately the example code is only available in the download archive (not on the web site) but here’s an overview of how it works:
import ezPyCrypto # Generate a 512 bit key key = ezPyCrypto.key(512) text = 'This will be encrypted' # Encrypt the string encrypted = key.encString(text) print encrypted # Unencrypt the string decrypted = key.decString(encrypted) print decrypted # Export the public key public = key.exportKey() # This can now be saved or distributed # Export the private key private = key.exportKeyPrivate() # This can now be saved somewhere safe # Encrypting using an already generated public key: key = ezPyCrypto.key() key.importKey(public) encrypted = key.encString(text) # Decrypting using an already generated private key: key = ezPyCrypto.key() key.importKey(private) decrypted = key.decString(text)
That’s pretty much it. The class also has support for passphrases which can be used to add an extra layer of protection to a private key, as well as methods to handle crypotgraphic signing and verification.
ezPyCrypto is an easy to use wrapper for the excellent PyCrypto module, and includes PyCrypto (and a handy Windows installer) in the distribution.
