OpenSSL (1988) is an open source implementation of the TSL cryptographic protocol, and its now-deprecated predecessor, Secure Sockets Layer (SSL) protocol.

CSR Examples[edit]

openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout private.key -out public.pem
Output a self-signed certificate instead of a certificate request
-nodes (short for no DES) do not encrypt private key
-x509 Output a self-signed certificate instead of a certificate request


  • Read certificate (CRT)
openssl x509 -text -noout -in root.crt
openssl req -text -noout -in root.csr


Public keys[edit]

openssl rsa -in mykey.pem -pubout > mykey.pub
