It’s Dangerous: Python crypto library for signing data before sending through untrusted environments

It's Dangerous logo

(via)

“Various helpers to pass data to untrusted environments and to get it back safe and sound.”

From the website:

Example Use Cases

  • You can serialize and sign a user ID for unsubscribing of newsletters into URLs.
    This way you don’t need to generate one-time tokens and store them in the database.
    Same thing with any kind of activation link for accounts and similar things.
  • Signed objects can be stored in cookies or other untrusted sources which means you don’t need to have sessions stored on the server,
    which reduces the number of necessary database queries.
  • Signed information can safely do a roundtrip between server and client in general which makes them useful for passing server-side state
    to a client and then back.
