Simple JavaScript encryption & decryption without using key
提问by blasteralfred Ψ
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?
我想知道是否可以使用纯 JavaScript 加密和解密文本。我不想使用 key。它可能是一种入门杠杆解决方案。但我只是想将文本“my-name-1”编码为某种文本格式,并想从中检索文本。在不使用任何 js 库的情况下,这可能吗?

Without a key (or some secret for that matter), you wont get any kind of encryption.
如果没有密钥(或与此相关的一些秘密),您将无法获得任何类型的加密。
What you mean is something like a different encoding. So maybe Base64 is something for you.
你的意思是类似于不同的编码。所以也许 Base64 适合你。
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+.
这在所有主要浏览器中都受支持。仅在 IE10+ 中支持 IE。
