The format used looks like this: >>> signing.dumps("hello") 'ImhlbGxvIg:1QaUZC:YIye-ze3TTx7gtSv422nZA4sgmk' There are two components here, separated by a ':'. The first component is a URLsafe base64 encoded JSON of the object passed to dumps(). The second component is a base64 encoded hmac/SHA-256 hash of "$first_component:$secret" signing.loads(s) checks the signature and returns the deserialized object. If the signature fails, a BadSignature exception is raised. >>> signing.loads("ImhlbGxvIg:1QaUZC:YIye-ze3TTx7gtSv422nZA4sgmk") 'hello' >>> signing.loads("ImhlbGxvIg:1QaUZC:YIye-ze3TTx7gtSv42-modified") ... BadSignature: Signature "ImhlbGxvIg:1QaUZC:YIye-ze3TTx7gtSv42-modified" does not match You can optionally compress the JSON prior to base64 encoding it to save space, using the compress=True argument. This checks if compression actually helps and only applies compression if the result is a shorter string: >>> signing.dumps(list(range(1, 20)), compress=True) '.eJwFwcERACAIwLCF-rCiILN47r-GyZVJsNgkxaFxoDgxcOHGxMKD_T7vhAml:1QaUaL:BA0thEZrp4FQVXIXuOvYJtLJSrQ' The fact that the string is compressed is signalled by the prefixed '.' at the start of the base64 JSON. There are 65 url-safe characters: the 64 used by url-safe base64 and the ':'. These functions make use of all of them.
