Generate Pem Key
Openssl genrsa -des3 -out private.pem 2048 That generates a 2048-bit RSA key pair, encrypts them with a password you provide and writes them to a file. You need to next extract the public key file. Having previously generated your private key, you may generate the corresponding public key using the following command. $ openssl pkey -in private-key.pem -out public-key.pem -pubout You may once again view the key details, using a slightly different command this time.
