Share python-based logon and operations with Kaixin.com scripts

This article mainly introduces python login and operation of Kaixin.com script sharing. you can log on to Kaixin.com and send messages after logon. if you need it, you can refer to SNS and other functions that I have never liked, this time, I wrote a script to log on to kaixin001 and send intra-site messages to all friends.

Kaixinnet did some processing during login without passing the original password. the result from js analysis is that a random key will be generated during login, then, use the key and the original password for xxtea encryption, and then encrypt the encrypted result with sha1. Then post the key and the encrypted password for logon verification.

The following is a simple script:

This is the python implementation (xxtea. py) of the xxtea algorithm used in the script ):
