When you try to orchestrate all this via python using python libraries, you add a layer of abstraction which is more trouble than its worth in my opinion. Versioning issues with python can arise over time. If you invoke the gpg commands above within your python code instead it is a more reliable solution. Best of Luck!

More, according to my little experience of using PyCrypto, the IV is used to mix up the output of a encryption when input is same, so the IV is chosen as a random string, and use it as part of the encryption output, and then use it to decrypt the message.

Apr 7, 2010 · Looking to store usernames and passwords in a database, and am wondering what the safest way to do so is. I know I have to use a salt somewhere, but am not sure how to generate it securely or how to apply it to encrypt the password. Some sample Python code would be greatly appreciated. Thanks.

May 5, 2015 · RSA encryption only works on small block sizes so to do a whole file you would need to encrypt it in chunks , this is pretty slow. Its better to use a hybrid encryption scheme where you encrypt the data with a random AES key then encrypt the AES and Nonce with the RSA key , you can store the encrypted key and nonce with the encrypted data for ...

Aug 21, 2012 · the secure way is encrypt your sensitive data by AES and the encryption key is derivation by password-based key derivation function (PBE), the master password used to encrypt/decrypt the encrypt key for AES. master password -> secure key-> encrypt data by the key. You can use pbkdf2

pyDES is a DES and Triple-DES implementation completely written in python. Here's a simple and portable example that should be secure enough for basic string encryption needs. Just put the pyDES module in the same folder as your program and try it out:

I've actually seen commercial python code shipped as embedded python inside of a C library. Instead of converting some parts of the code to C, they hide the entire python code inside a protective C layer. Then, if they want a module importable by python, they write a thin python extension on top of the C. Open source is a much easier way of life.

Sep 3, 2014 · Cryptography provides some basic tools, such as symmetric encryption or digital signatures. Assembling those tools into a communication protocol is devilishly difficult, and when I invoke the name of the Devil I mean it: it looks easy, but there are many details, and it is known that the Devil hides in the details.
