OpenSSL command to generate RSA private keys. More information: https://www.openssl.org/docs/manmaster/man1/openssl-genrsa.html.

• Generate an RSA private key of 2048 bits to stdout:
  openssl genrsa
• Save an RSA private key of an arbitrary number of bits to the output file:
  openssl genrsa -out {{output_file.key}} {{1234}}
• Generate an RSA private key and encrypt it with AES256 (you will be prompted for a passphrase):
  openssl genrsa {{-aes256}}
