Issue when encrypt

[celciusjj]

Error: exception decoding Hex string: invalid characters encountered in Hex string

[arunahuja94]

Getting same error, have you found any solutions?

I also had this issue, my key + IV used had special characters in, i.e an =

If you just a normal alphanumeric key + IV, i.e say
591825e3a4f2c9b8f73eb963c77ad160d4802ad7aadc179b066275bcb9d9cfd2 then it seems to work.. seems rather counter intuitive, particularly if you're generating random keys.
const cipherText = await Aes.encrypt(data, "591825e3a4f2c9b8f73eb963c77ad160d4802ad7aadc179b066275bcb9d9cfd2", "0123456789abcdef0123456789abcde");

const randomKey = await Aes.randomKey(32);
const randomIv = await Aes.randomKey(16);

const cipherText = await Aes.encrypt(data, randomKey, randomIv);

Im getting the same error.

i let my code here, if you found any solution please let me know.

function buildSign(data, config) {
  try {
    encryptData(data.toString(), config)
    .then(({ cipher, iv }) => {
        console.log('Encrypted:', cipher)

        Aes.hmac256(cipher, config).then(hash => {
            console.log('HMAC', hash)
        })
    })
    .catch(error => {
        console.log(error)
    })

  } catch (e) {
    console.error(e)
  }
  //return crypto.createHmac('sha256', config.API_SECRET).update(data).digest('hex');
}

Thank you so much!
Sorry for my english. 😋

same issue, but apparently you should try to generate a random key rather then passing your own key, that was the issue for me i added my own key that had apparently invalid caracters, use this instead

const handleSubmitForm = async (values, hash) => {
const randomIv = await Aes.randomKey(16);

try {
  console.log('Key:', randomIv);
  encryptData('k]]xM2uPFpkLWPBas&}46^FN.H9738', randomIv)
    .then(({cipher, iv}) => {
      console.log('Encrypted:', cipher);
    })
    .catch(error => {
      console.log('error', error);
    });
} catch (e) {
  console.error(e);
}

};

As far as I can see, this means we can't use this package as a drop in replacement for nodejs version of crypto or use it alongside nodejs. E.g, if a developer needs to use hmac256 as part of a HTTP header authorization request, it will fail because the key used on the server will be different to the one used with this package, and therefore produce two very different hashes.
