Suggested enhancement

Question

Please first check for answers in the Mbed TLS knowledge Base, and preferably file an issue in the Mbed TLS support forum

@meghaamity Thank you for your query Mbed TLS does not support at the moment Edwards 25519 curve, for signing and verifying, hence the failure you are receiving.

Note that the Montgomery curve is used for ECDH, while Edwards is used for sign\verify.

I need Edwards sign\verify as per RFC 8032.It is not present as if now. By when will it be available?

RonEld commented 6 years ago

@meghaamity We don't publicly publish our roadmap, so unfortunately I can't update when and if it will be supported. We will take into consideration your requirements.

Note that this is a duplicate of #388 hence closing this issue
