Key exchange algorithms (wodFtpDLX / wodFtpDLX.NET)

Hi there,

We've been asked to make an SFTP connection using ecdsa-sha2-nistp521, which doesn't seem to be working.

Does wodFtpDLX.Net currently support this? Is it likely to in the future?

Also, is it possible for enumerations to be added for all the supported algorithms? The existing enums such as EncryptionMethods are quite useful to have as a reference, even if we don't usually set/get them in our code.

Thanks.

Hi,

no we support ecdsa-sha2-nistp256 and ecdsa-sha2-nistp384 but not nistp521. Note that it is supported only in NET Core and NET Framework 4+ version, and support is partial - in rare cases exception is thrown for invalid signature so we put them at the end of client offer list.

We could add nistp521 if needed with same limitation - if connection fails with 'signature invalid', reconnect. Would that help?

Hi Jasmine, thanks for that. Yes it would be useful to have that nistp521 support, even if it is partial.

Hi,

done, please request update and get latest 1.9.6.286, you should find it supports ecdsa-sha2-nistp521

Regards,
Jasmine
