Any ideas how I can get the two to interoperate? PyCrypto doesn't handle the padding so I was doing it myself just add ' ' in both. Just for any one that is similar to me, who was finding a simple way to do the encryption and decryption for AES in python that is doing the same thing in node. The class here supports different bits of AES and both hex and base64 encoding that produces same result in node.

Encrypting and Decrypting with python and nodejs Ask Question. Asked 9 years, 11 months ago. Modified 7 months ago. Viewed 16k times. I'm trying to encrypt some content in Python and decrypt it in a nodejs application. Improve this question. It should be a new, random value for each message. It also should have the same size as the block size, and not half the block size, as in your example.

Thanks CodeInChaos this is sample code so I simplified some of it. Add a comment. Sorted by: Reset to default. Highest score default Date modified newest first Date created oldest first. So updated working code. Improve this answer. There's a small bug in your Node. Thanks, I've fixed it in the answer now — dave. Thank you so much for the examples. The above command will create a new package.

Make sure that you have already installed Node. By default, the crypto module is already included in pre-built Node. But if you have manually installed Node. However, you can install it by executing the following command:. Let us create the crypto. The following example demonstrates that how you can encrypt and decrypt text data strings, numbers, etc. You can also encrypt and decrypt buffers by using the functions defined above.

Just pass the buffer in place of the string and it should work:. You can also encrypt and decrypt streams by using the crypto module as shown in the following example:. In this article, we looked at how to perform cryptographic operations on text, buffers, and streams by using Node.

This is extremely useful if you need to encrypt sensitive data like secret keys before storing them in a database. Follow me on Twitter and LinkedIn.
