Support for SM4 (Chinese National Standard)

Applications deployed in China are required to transition from AES to SM4 due to regulatory requirements. BouncyCastle, OpenSSL, and other crypto libraries have already added support for these Chinese algorithms (SM2, SM3, SM4). Is this something that’s likely to be offered in the future?

Would community contribution be suitable for this?


@akhilvelagapudi hank you for your query !
As you can see in and, The work on SM2 and SM4 has started, however we can’t commit on when it will be merged as they still require additional work.
You are welcome to watch these PRs for their progress.
