python3-itsdangerous 0.24+dfsg1-2 (amd64 binary) in ubuntu bionic

 itsdangerous provides a module that is a port of the django signing
 module. It's not directly copied but some changes were applied to
 make it work better on its own.
 .
 itsdangerous allows web applications to use a key only it knows to
 cryptographically sign data and hand it over to someone else (e.g. a
 user). When it gets the data back it can easily ensure that nobody
 tampered with it.
 .
 This package provides the itsdangerous Python module for Python 3.x.
