Does the SSH server support ED25519 keys?

Looking on line I found this webpage that says that Securebridge does support ED25519 but when I tried to import the key it gave an error of "Invalid Public Algorithm".

Here is the link that says securebridge supports this key.
https://devart.uservoice.com/forums/174 ... 19-support

I am running Version 8.1.2.
In the release note for version 8.0.1 it says....
•Elliptic Curve Key Exchange algorithm in SSH protocol is supported

I created the key with Putty Key Generator and had it make a public key file and private key file and then tried to import the public key into SSH server and got the error.

So I am trying to figure out is ED25519 not supported or is it an issue with what Putty Key Generator made???

I also did not see how to make a ED25519 key pair with Generate.
Looking in the help the only algorithms shown are
procedure Generate(const Algorithm: TScAsymmetricAlgorithm; const BitCount: integer; Random: TScRandom = nil);
TScAsymmetricAlgorithm = (aaDSA, aaRSA);


Thanks
Tom

We supported Elliptic Curve Key Exchange algorithms in SSL and SSH protocols, but not working with ecdsa or ed25519 keys using the TScKey component. We will add this functionality in one of the next releases of SecureBridge.

Are there any news or an ETA on the ecdsa implementation (as Host Key Algorithm for the SSH Client)?

Support for working with ECDSA keys using the TScKey component will be included in the next build of SecureBridge, which we plan to release within a month.
