Instead of self signed certificate. We can create our own CA signed Certificate. Note, it requires to import CA public key to our truststore in this case.

steps

• generate ca private key. (Need a password)

  openssl genrsa -aes256 -out CAPrivate.key 2048

• generate CA public key. Use password created before (Need to import this public key to client truststore to establish trust).

  openssl req -new -x509 -key CAPrivate.key -sha256 -days 3650 -out FakeCA.pem

• Generate a private key for sever. Need a password as well.

  openssl genrsa -aes256 -out www.fakesite.key 2048

• generate a certificate signing request

  openssl req -new -key www.fakesite.key -out www.fakesite.csr

• sign the csr

  openssl x509 -req -in www.fakesite.csr -CA FakeCA.pem -CAkey CAPrivate.key -CAcreateserial -out www.fackesite.crt -days 365 -sha256

• Now you should have signed crt.

  CAPrivate.key
  FakeCA.pem
  FakeCA.srl
  www.fackesite.crt
  www.fakesite.csr
  www.fakesite.key
