[Feature] Press Enter/Return in the Textbox to Decrypt

[Unkn0wnCreator]

Hi,

You could add this to the end of the secret-template file, within the script tag, to allow that.

document.querySelector("#password").addEventListener("keyup", event => {
if(event.key !== "Enter") return;
decrypt()
event.preventDefault();
});

Thank you very much. I'll get to it eventually.
