Asymmetric encryption

For Asymmetric encryption you must first generate your private key and extract the public key.

openssl genrsa -aes256 -out c_passwd_prv.key 8192
openssl rsa -in c_passwd_prv.key -pubout -out c_passwd_pub.key

To encrypt:

openssl rsautl -encrypt -pubin -inkey c_passwd_pub.key -in <(echo "THE PASSWORD TEXT") -out encrypted_c_passwd.enc

To decrypt:

openssl rsautl -decrypt -inkey c_passwd_prv.key -in encrypted_c_passwd.enc -out plaintext.txt
