I have NestJS api which crypt and decrypt string with next code

export const encryptIV = async (data:string)=>{
    try{
        const iv = Buffer.from('q2Q@w3W#').toString('hex');
        const secretKey = 'H4WtkvK4qyehIe2kjQfH7we1xIHFK67e';
        const key = (await promisify(scrypt)(secretKey, 'salt', 32)) as Buffer;
        const cipher = createCipheriv(alg, key, iv);

        let encryptedText = cipher.update(data,'utf-8','hex');
        encryptedText += cipher.final('hex');

        return `${encryptedText}`;
    } catch (e){
        return '';
    }
}


export const decryptIV = async (data:string)=>{
    try{
        if (data.length>0){
            const iv = Buffer.from('q2Q@w3W#').toString('hex');
            const secretKey = 'H4WtkvK4qyehIe2kjQfH7we1xIHFK67e';
            const key = (await promisify(scrypt)(secretKey, 'salt', 32)) as Buffer;
            const decipher = createDecipheriv(alg, key, iv);
            let decryptedText = decipher.update(data,'hex','utf-8');
            decryptedText += decipher.final('utf-8');
            return decryptedText;
        } else {
            return '';
        }
    } catch (e){
        return '';
    }
}

Decryption in JS:

IV="7132514077335723"
SecretKey="H4WtkvK4qyehIe2kjQfH7we1xIHFK67e"
EncryptedData="222ef6e4c66c3dfdea9cf1f4828f436e"
AfterDecryption="28c9c0e555b71fda"
ALG="aes-256-ctr"

I’m trying decrypt my encryptedData in dart using “encrypt: ^5.0.3” package with next code:

void decrypt() {
  try{
    final hexIv = "222ef6e4c66c3dfdea9cf1f4828f436e";
    final ivHexIv = enc.IV.fromUtf8("7132514077335723");
    final ivKey = enc.Key.fromUtf8('H4WtkvK4qyehIe2kjQfH7we1xIHFK67e');
    final enc.Encrypter encrypterIv = enc.Encrypter(enc.AES(ivKey,mode: enc.AESMode.cbc));
    final String decrypted =encrypterIv.decrypt64(hexIv, iv: ivHexIv);
    setState(() {
      text=decrypted;
    });
  } catch (e){
    debugPrint(e.toString());
  }
}

In this code I’m geting “Input data length must be a multiple of cipher’s block size” error
