I have asked this question before for React here.

I'm using crypto-es which is based on CryptoJS. I've used this is react like this

function decryptByDES(ciphertext) {
    var keyHex = CryptoJS.enc.Utf8.parse("38346591");

    // direct decrypt ciphertext
    var decrypted = CryptoJS.DES.decrypt(
      {
        ciphertext: CryptoJS.enc.Base64.parse(ciphertext),
      },
      keyHex,
      {
        mode: CryptoJS.mode.ECB,
        padding: CryptoJS.pad.Pkcs7,
      }
    );

    return decrypted.toString(CryptoJS.enc.Utf8);
  }

However using the same function in react-native gives me this error:

Test data:

encrypted text: "ID2ieOjCrwfgWvL5sXl4B1ImC5QfbsDycMwuqSNl+oXFQYM2ahEKHjJ8S9AMOijqZzashfXSBli0hxaWMyCdjhw7tS9a8Gtq"

expected decrypted result: https://aac.saavncdn.com/881/374283a91cd721f65f59e3a49e6f5623_96.mp4

secret key: 38346591
