Crypto JS decrypt in Java

CryptoJS is a popular JavaScript library that provides AES encryption and decryption functionality. If you want to decrypt data that was encrypted using CryptoJS in a Java application, you can use the Java version of the AES encryption algorithm to do so. Here is an example of how you can use the Java Cipher class to decrypt data that was encrypted using CryptoJS: import java.util.Base64; import javax.crypto.Cipher; import javax.crypto.spec.SecretKeySpec; public class Decryptor { public static String decrypt(String encryptedData, String key) throws Exception { SecretKeySpec secretKey = new SecretKeySpec(key.getBytes(), "AES"); Cipher cipher = Cipher.getInstance("AES"); cipher.init(Cipher.DECRYPT_MODE, secretKey); byte[] decryptedData = cipher.doFinal(Base64.getDecoder().decode(encryptedData)); return new String(decryptedData); } } To use this decryptor class, you would pass in the encrypted data as a base64 encoded string and the key that was used to encrypt the data. The decrypt method will then return the decrypted data as a string. It's important to note that the key used to decrypt the data must be the same key that was used to encrypt the data. If a different key is used, the decryption process will fail.
