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: https://github.com/ARMmbed/mbedtls/projects/2#column-11150355

Kind regards, Janos

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
