Can someone help me with the command to generate a self-signed certificate using openssl?
I have used the following steps and when I get a certificate and open up it says "the signature is invalid". Am I missing something? I have created an ECC key pair using the following: openssl ecparam -out key.pem -name prime256v1 -genkey I create the request using the following openssl req -new -key key.pem -out req.pem I create the self-signed certificate using the following openssl req -x509 -in req.pem -days 365 -key key.pem I cannot tell why the certificate that is generated doesn't work. I am pasting the generated certificate as well -----BEGIN CERTIFICATE----- MIICJzCCAc6gAwIBAgIJANJO0K9iY9obMAkGByqGSM49BAEwRTELMAkGA1UEBhMC VVMxEzARBgNVBAgTClNvbWUtU3RhdGUxITAfBgNVBAoTGEludGVybmV0IFdpZGdp dHMgUHR5IEx0ZDAeFw0wODAyMTMwNTM3MzlaFw0wOTAyMTIwNTM3MzlaMEUxCzAJ BgNVBAYTAlVTMRMwEQYDVQQIEwpTb21lLVN0YXRlMSEwHwYDVQQKExhJbnRlcm5l dCBXaWRnaXRzIFB0eSBMdGQwWTATBgcqhkjOPQIBBggqhkjOPQMBBwNCAATzJjKX 0dv55hhAU5X3Z/erUiWWqljSjtxt06XlXRGV53P5syTfXk+xXlVJZj6kOTzFpHTw o2I1lCOq5duDZwc1o4GnMIGkMB0GA1UdDgQWBBTmmxgUf1KI68WGvrNonr4586Yr 4jB1BgNVHSMEbjBsgBTmmxgUf1KI68WGvrNonr4586Yr4qFJpEcwRTELMAkGA1UE BhMCVVMxEzARBgNVBAgTClNvbWUtU3RhdGUxITAfBgNVBAoTGEludGVybmV0IFdp ZGdpdHMgUHR5IEx0ZIIJANJO0K9iY9obMAwGA1UdEwQFMAMBAf8wCQYHKoZIzj0E AQNIADBFAiEAp1igUmK+Qt1Tg21MxE/dliRW9fhrduw/z/oLQYxsS4UCICQArqf7 GzfPd/Y+Lkci7bohC3kyMToHKy8yDoFPjOuw -----END CERTIFICATE----- Thanks, Nabil
