I still haven’t manged to have any luck importing the ECC key. I started down this path wanting to use derived keys but discovered in this thread that you can’t export the key for backup, which means reliance on Onlykey which I’d like to avoid.
So for my particular use case, I’m looking at stored keys. As I said I can use RSA keys but I need more than four, so ECC seems to be the only way to go. Is there some documentation on how to import ECC keys created by GPG? As I understand it GPG ECC keys are compatible with the OpenPGP standard.
What else can I do to troubleshoot this? If I must use raw keys how do I convert an ASCII armored key to the required format?
