how to use custom encryption algorithm for data encryption.

[jennyjin007]

i want to use SM4 algorithm, while ShardingSphere only support AES by default. Anybody got experience on using custom encryption algorithm? How to config the encryptors? Is 'CUSTOM' type correct?

Chat GPT gave the following demo:
encryptors:
sm4_encryptor:
type: CUSTOM
props:
algorithmClassName: com.example.SM4EncryptAlgorithm
key: your_sm4_key

Refs:
"Users can implement the interface to use a custom encryption algorithm for data encryption."
https://shardingsphere.apache.org/document/current/en/reference/encrypt/#the-advantages-of-middleware-encryption-service

BTW, the following map shows SM3,SM4 in built-in algorithm list, is this a typo?

Hi @jennyjin007, you can find the sm3 and sm4 algothrim in ShardingSphere plugin repository.
