Simple JavaScript encryption & decryption without using key

rated 0 times [ 101] [ 7] / answers: 1 / hits: 23514 / 11 Years ago, fri, may 17, 2013, 12:00:00

I would like to know if it is possible to encrypt and decrypt a text, using pure JavaScript. I don't want to use a key. It may be an entry lever solution. But I simply want to encode a text my-name-1 into some text format and want to retrieve the text from it. Is this possible, without using any js libraries?

Without a key (or some secret for that matter), you wont get any kind of encryption.

What you mean is something like a different encoding. So maybe Base64 is something for you.

var baseString = 'my-name-1';



var encodedString = window.btoa( baseString ); // returns bXktbmFtZS0x



var decodedString = window.atob( encodedString );  // returns my-name-1

This is supported in all major browsers. IE support just in IE10+.

Base64

window.btoa()

window.atob()
