To encrypt a message, type:
$ node aes.mjs encrypt my-secret.json
Enter password:
password: hello12345
Then type messages:
type messages (type EOF to end):
Hello, this is a secret file!
Using AES encryption!
EOF
When EOF entered the message was end, and the encrypted data saved as JSON file:
encrypted data saved: my-secret.json
{
"hash-alg": "sha256",
"message-iv-hash": "2fb92934a7b17cafef3a5e29212b0bd73ee035d80294bdaa16fdeb34742eaa46",
"encrypt-alg": "aes-256-cbc",

"pbkdf2-iterations": 999999
}
To decrypt a message, type:
$ node aes.mjs decrypt my-secret.json
Enter password:
password: hello12345
If password is correct, the decrypted message is display:
Decrypted ok:
Hello, this is a secret file!
Using AES encryption!
Both the password and message are input by keyboard in terminal, and never saved into file.
The saved encrypted JSON file can be safely backed up.
