I'm trying to extract the certificate chain from a pkcs7 file, but I get the error 'Cannot read public key. OID is not RSA.' I understand that I'm getting that because this package doesn't support ecdsa, but was wondering if anyone can point me to a package that does something similar or if anyone has any solutions. I'm new to this and am having trouble figuring out what to do.
