Hi all,

Does openssl supports sign and verification using ECC 25519 curve Bernstein?

Hi,

I am using Qnx 7.0.0 which make use of openssl 1.0.2j.

Can you please confirm if I can use ECC related api from openssl which is supported by openssl 1.1.0.

OpenSSL 1.1.0 does not support sign/verify using 25519 (i.e. Ed25519).
That is only available in OpenSSL 1.1.1.

Shameless self plug -- libsuola is an OpenSSL engine providing
curve25519 and ed25519 support for 1.0.2, 1.1.0, and 1.1.1:

https://github.com/romen/libsuola

With different "backends" including libsodium or formally verified HACL*.
