For signing firmware images, we are using OpenSSL v1.1.1f, which I think was provided by Netburner. It's been about 4-years since we started signing images. In any case, is it possible to use the current version of OpenSSL, which I think is v3.5.0, to create the private/public key pair?
Am I correct to assume that if we change OpenSSL versions, that images signed with the new version will be rejected by firmware signed with the original version?
