Are 8192-bit RSA SSH keys supported?

I assume 8192-bit RSA keys are not supported? When I try to import my existing key, the on the password prompt to decrypt the key I get this error:

We were unable to decrypt your SSH key. Try a different passphrase or select a new SSH key.

If I try and generate a RSA SSH key with 1Password, it caps out at 4096-bit keys.


1Password Version: 8.6.0
Extension Version: 2.2.3
OS Version: macOS 12.2 (21D49)

Never mind, I'm blind. I found the answer here: https://developer.1password.com/docs/ssh/manage-keys/#rsa

1Password supports 2048-bit, 3072-bit, and 4096-bit RSA keys.

That is correct. We are looking into supporting larger keys in the future, but do not have an expected timeframe.
