Hi Shudong,

Mbed TLS currently does not provide EdDSA. The contribution by @aurel32 is a first step in this direction. The work leading up to a fully functional EdDSA implementation is tracked here:

Kind regards,

Subject: [mbed-tls] Is the a version that can use the EdDSA signature algorithm currently?

Hello,

I want to use EdDSA signature algorithm, but I did’t find API for it in 2.26.0.Then I searched in the issue of Github and I found @aurel32 contributed some code about ed25519.But I am still not sure whether there are any versions under development that provide interface functions for EdDSA signature algorithm. Can someone help me answer my question?

Thanks and kind regards,

Shudong
