ssh-keygen.exe types DSA, ECDSA, RSA not supported

[byronigoe]

Please answer the following

"OpenSSH for Windows" version
Beta

Client OperatingSystem
Windows 10 Pro

What is failing
ssh-keygen lists various unusable encryption types in the help output:
usage: ssh-keygen [-q] [-b bits] [-t dsa | ecdsa | ed25519 | rsa]
[-N new_passphrase] [-C comment] [-f output_keyfile]
Try to use anything but ed25519 and it fails.

Expected output
Successful generation of a key pair.

Actual output
unknown key type dsa
unknown key type rsa
unknown key type ecdsa

Looks like you are using the windows inbox version of openssh. If yes the this is expected.. The initial version has support for only ed25519..

You can try our github version that has latest and greatest version..

Reopen if required

Should I expect Windows to eventually update the inbox SSH version to match the GitHub one? If yes, do you know when this could be expected?

(I’m particularly interested in RSA support.)

[bagajjal]

Yes, it will be in our next release.. I guess the next release is in April..

I just downloaded and installed the 1.0.0.0 release as per the instructions, and Get-Command tells me that the ssh-keygen being used is the one in C:\Program Files\OpenSSH\, yet it's telling me that RSA isn't supported as above.

[bagajjal]

Are you sure you are using 1.0.0.0?

[p0lar-bear]

...Nope. I thought I was but I misread the output of Get-Command, it was using 0.0.18.0. Disregard.
