FAQs

How to decrypt with CryptoJS? ›

Here´s the example extracted from the github of the library:

var CryptoJS = require("crypto-js");
// Encrypt.
var ciphertext = CryptoJS.AES.encrypt('my message', 'secret key 123').toString();
// Decryptvar.
bytes = CryptoJS.AES.decrypt(ciphertext, 'secret key 123');
var originalText = bytes.toString(CryptoJS.enc.Utf8);

What is the hardest encryption to decrypt? ›

AES 256-bit encryption is the strongest and most robust encryption standard that is commercially available today. While it is theoretically true that AES 256-bit encryption is harder to crack than AES 128-bit encryption, AES 128-bit encryption has never been cracked.

Can hackers decrypt data? ›

Hackers can break encryption to access the data using a number of different methods. The most common method is stealing the encryption key itself. Another common way is intercepting the data either before it has been encrypted by the sender or after it has been decrypted by the recipient.
