• To generate a private key we use the following command (8912 creates the key 8912 bits long):

openssl genrsa -aes256 -out private.key 8912

• To generate a public key we use our previously generated private key:

openssl rsa -in private.key -pubout -out public.key

• Lets now encrypt a file (plaintext.txt) using our public key:

openssl rsautl -encrypt -pubin -inkey public.key -in plaintext.txt -out encrypted.txt

• Now, if we use our private key, we can decrypt the file and get the original message:

openssl rsautl -decrypt -inkey private.key -in encrypted.txt -out plaintext.txt
