itsdangerous.js

... so better sign this.

Various helpers to pass data to untrusted environments and to get it back safe and sound. Data is cryptographically signed to ensure that a token has not been tampered with.

It's possible to customize how data is serialized. Data is compressed as needed. A timestamp can be added and verified automatically while loading a token.

Note: This is an unofficial Node.js port of the Python library itsdangerous.
