Simple JavaScript encryption & decryption without using key


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?


Solution

  • 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+.
