AES and Credit card number encryption

2007-01-22 Thread Tobiah
I browsed this subject and thought I might use the 'AES' cypher scheme to do this. Would this be a good choice? I came across a "Python Cryptography Toolkit" http://www.amk.ca/python/code/crypto which has a nice AES implementation, but in the example, a simple string is passed as the key: obj=
