Bug - op fails getting SSH key

Also running into this. Uploaded a key using OP UI. Was able to retrieve it just fine using an older version of OP CLI (not sure what it was). Then I accidentally updated the OP CLI to 2.22.0 and now cannot retrieve it (or the public key field on it) with the same error as @alonz

Hi @jamesdh and @alonz. I tried reproducing this by importing RSA private keys both in PKCS8 and OpenSSH formats but with no success. I think it's important to find out what standard your problematic RSA key is following. How many bits does it have? On what date was it created approximately? In what format was it displayed (e.g. in its id_rsa file)?

Hi @andi_t_1P thank you for looking into it.
I don't recall when or how this key was created possibly it was created by an older openSSH or I think it might have been created by Amazon as part of AWS EC2 deployment
looking at such problematic keys I can see that it's 2048 bit and it is in the format of

-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----


I can confirm that newer keys that I create in the format of "-----BEGIN OPENSSH PRIVATE KEY-----" seem to work without an issue.

with the above hint I was able to reproduce the issue using

ssh-keygen -t rsa -b 2048 -m PEM -f <filename>

which in turn leads to the following ERROR message when downloading it from OP using cli
```
[ERROR] 2023/11/27 13:54:27 unsupported key type "RSA PRIVATE KEY" passed with the PEM

```

Hi @andi_t_1P

Thanks for looking into this and sorry for pestering. Do you have status update for this bugfix?

I believe @alonz has provided sufficient repro steps but, just in case, here is a RSA key in PEM format that fails:


$ ssh-keygen -t rsa -N "" -b 2048 -m PEM -f test_private_key
$ cat test_private_key
-----BEGIN RSA PRIVATE KEY-----

I confirm I was able to reproduce this.

The problem is that the output of ssh-keygen -t rsa -N "" -b 2048 -m PEM -f test_private_key is a an older PEM block format called pkcs#1 (apparent from the header "BEGIN RSA PRIVATE KEY" as opposed to simply "BEGIN PRIVATE KEY"). 1Password internally supports pkcs#8 and openSSH.

I created an internal issue for supporting your use case as well, but I make no promises as to when this will hit stable, although I don't expect a lot of CLI releases to pass without this being solved.

In the meantime, as a workaround, you can consider generating an RSA key and storing it in pkcs8 pem format: ssh-keygen -m PKCS8 -t rsa before importing it into 1Password.

Thanks for looking into this promptly @andi_t_1P !
