unable to add my ssh key

Question

Hello,

I keep receiving "Invalid key" when I try to add a new key to my personal bitbucket account (but it works in other contexts).

I suspect the problem here is the key type: ssh-dss. Is it possible?

This is what I'm trying to paste (one single line):

ssh-dss AAAAB3N...2104 more characters...UsRI= user@example.com

Any advices?

Looks like we found the cause... Why isn't this in the docs?

DSA keys list themselves as "ssh-dss", so that isn't the issue here. However, the key length may be incompatible - Bitbucket limits DSA keys to 1024 bits, and will reject other sizes. (RSA keys can be 2048 bits or more; ECDSA keys can be 256, 384, or 521 bits; and Ed25519 keys are always 256 bits.)

Hi Sergio,

Welcome to the community!

Bitbucket only supports four encryption algorithms for user keys: Ed25519, ECDSA, RSA, and DSA, so make sure your key was created using one of those.
