Python makes the spike encryption and decryption tool

It has been a long time since I wrote a technical blog, because I have been learning knowledge recently and haven't summarized anything worth sharing, so I have stopped writing until now. The recent work and the development of nailing have been handed in. The official did not provide any SDK of Python, so I had to write all by myself. Now I will implement the relatively time-consuming "encryption/decryption/signature" part of the share, I hope to help 1 people.
The specific mechanism of encryption/decryption can be referred to the official documents.
To install this extension in your project, you can use:
pip install dingtalk_crypto
The installation.
To use it, refer to the following test code:
# -*- coding: utf-8 -*-
import json
from dingtalk_crypto import DingTalkCrypto
# This is the testing data from the nailing authority
# @see https://open-doc.dingtalk.com/doc2/detail.htm?treeId=175&articleId=104945&docType=1#s14
encrypt_text = '1a3NBxmCFwkCJvfoQ7WhJHB+iX3qHPsc9JbaDznE1i03peOk1LaOQoRz3+nlyGNhwmwJ3vDMG' \

'/D6Ibr0rgUathB6zRHP8PYrfgnNOS9PhSBdHlegK+AGGanfwjXuQ9+0pZcy0w9lQ=='
crypto = DingTalkCrypto(
'4g5j64qlyl3zvetqxz5jiocdr586fn2zvjpa8zls3ij',
'123456',
'suite4xxxxxxxxxxxxxxx'
)
signature = '5a65ceeef9aab2d149439f82dc191dd6c5cbe2c0'
timestamp = '1445827045067'
nonce = 'nEXhMP4r'
class TestCrypto:
def test_decrypt(self):
randstr, length, msg, suite_key = crypto.decrypt(encrypt_text)
msg = json.loads(msg)
assert msg['EventType'] == 'check_create_suite_url'
assert msg['Random'] == 'LPIdSnlF'
assert suite_key == 'suite4xxxxxxxxxxxxxxx'
def test_encode(self):
encrypt_msg = crypto.encrypt('hello world')
randstr, length, msg, suite_key = crypto.decrypt(encrypt_msg)
assert msg == 'hello world'
def test_check_signature(self):
assert crypto.check_signature(encrypt_text, timestamp, nonce, signature)
def test_sign(self):
msg = crypto.encrypt('hello world')
actual_sig, actual_time, actual_nonce = crypto.sign(msg)
assert True
Finally, posted the project source code address, hope to 1 some communication.
