Flask Session Verify

Category: Authentication

Status: Registered and callable in the CyberChef 11.3.0 compatibility inventory.

Input / output: string → JSON

What it does

Verifies the HMAC signature of a Flask session cookie (itsdangerous) generated.

Note

Status here means the operation name is implemented and callable. It does not by itself promise byte-for-byte parity for every upstream option. See Compatibility and current status for the verified scope and known boundaries.

Arguments and options

Arguments are positional. Keep their order when using bake() or Pipeline.then().

Index	Name	UI type	PyChef default	Accepted values / format
`0`	Key	`toggleString`	`{'string': '', 'option': 'Hex'}`	`''`
`1`	Salt	`toggleString`	`{'string': 'cookie-session', 'option': 'UTF8'}`	`'cookie-session'`
`2`	Algorithm	`option`	`'sha1'`	`'sha1'`, `'sha256'`
`3`	View TimeStamp	`boolean`	`True`	`True` or `False`

Recipe template

Important

This is a call template built from the documented defaults. Replace placeholder values such as empty keys, paths, patterns, or lookup data before running it.

from pychef import bake

input_value = "example"
args = [{'string': '', 'option': 'Hex'}, {'string': 'cookie-session', 'option': 'UTF8'}, 'sha1', True]
result = bake(input_value, [{"op": 'Flask Session Verify', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = [{'string': '', 'option': 'Hex'}, {'string': 'cookie-session', 'option': 'UTF8'}, 'sha1', True]
transform = Pipeline().then('Flask Session Verify', *args)
result = transform("example")

Dedicated operation module

The registered entry point lives in pychef.operations.by_operation.flask_session_verify. Direct calls receive the input value and a positional argument tuple:

from pychef.operations.by_operation.flask_session_verify import run

result = run("example", tuple([{'string': '', 'option': 'Hex'}, {'string': 'cookie-session', 'option': 'UTF8'}, 'sha1', True]))

pychef.operations.by_operation.flask_session_verify.run(value, args)

Run this operation using its shared internal implementation.

Parameters:

value (str | bytes)
args (Sequence[Any])

Return type:

str | bytes
