 ## Overview
 
 ️🔧 BlueKing crypto-python-sdk is a lightweight cryptography toolkit based on encryption libraries such as pyCryptodome
-and tongsuopy, providing a unified encryption and decryption implementation for Python applications, facilitating
-non-intrusive switching between different encryption methods in projects.
+and tongsuopy, providing a unified encryption and decryption implementation for Python applications, making it easy for

 ## Features
 
-* [Basic] Provides a unified encryption abstraction layer, docks with Cryptodome / tongsuopy and other encryption
-  libraries, and provides a unified encryption and decryption implementation.
-* [Basic] Supports mainstream international cryptography algorithms: AES, RSA.
-* [Basic] Supports Chinese commercial cryptography algorithms: SM2, SM4.
-* [Basic] Asymmetric encryption supports CBC, CTR, GCM, CFB as block cipher modes.
-* [Contrib] Django Support, integrated Django settings, ModelField.
