Scala to Scala works well, JS to Scala works well. But it did not work for Scala to JS. However, if I encrypted a simple Json in Scala like: {"name": "dung"}, it works well.
Scala code:
def encryptData(data: String) = {
val saltBytes = Array[Int](0x12, 0x34, 0x56, 0x78, 0x12, 0x34, 0x56, 0x78, 0x78, 0x90, 0x12, 0x34, 0x90, 0x12, 0x34, 0x56) map {_.asInstanceOf[Byte]}
val ivBytes = Array[Int](0x12, 0x34, 0x56, 0x78, 0x90, 0xab, 0xcd, 0xef, 0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56) map {_.asInstanceOf[Byte]}
val ivParamSpec = new IvParameterSpec(ivBytes)
val secretKey = genSecretKey("somekey", saltBytes)
val cipher = Cipher.getInstance("AES/CBC/PKCS5Padding")
cipher.init(Cipher.ENCRYPT_MODE, secretKey, ivParamSpec)
val encryptedData = cipher.doFinal(data.getBytes("UTF-8"))
val encodedData = (new BASE64Encoder()) encodeBuffer(encryptedData)
Json.obj(
"salt" -> DatatypeConverter.printHexBinary(saltBytes),
"iv" -> DatatypeConverter.printHexBinary(ivBytes),
"data" -> encodedData
)
}
def decryptData(encryptedData: EncryptedData) = {
val saltBytes = DatatypeConverter.parseHexBinary(encryptedData.salt)
val ivBytes = DatatypeConverter.parseHexBinary(encryptedData.iv)
val ivParamSpec = new IvParameterSpec(ivBytes)
val secretKey = genSecretKey("somekey", saltBytes)
val cipher = Cipher.getInstance("AES/CBC/PKCS5Padding")
cipher.init(Cipher.DECRYPT_MODE, secretKey, ivParamSpec)
val decodedValue = (new BASE64Decoder()) decodeBuffer(encryptedData.data)
val decryptedData = new String(cipher.doFinal(decodedValue))
decryptedData
}
Javascript code:
function encrypt(data) {
var salt = CryptoJS.lib.WordArray.random(128/8);
var iv = CryptoJS.lib.WordArray.random(128/8);
var secretKey = "somekey";
var key128Bits100Iterations = CryptoJS.PBKDF2(secretKey, salt, { keySize: 128/32, iterations: 100 });
var encrypted = CryptoJS.AES.encrypt(JSON.stringify(data), key128Bits100Iterations, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 });
return {
salt: String(salt),
iv: String(iv),
data: String(encrypted)
};
}
function decrypt(obj) {
var salt = CryptoJS.enc.Hex.parse(obj.salt);
var iv = CryptoJS.enc.Hex.parse(obj.iv);
var encrypted = obj.data;
var key = CryptoJS.PBKDF2("somekey", salt, { keySize: 128/32, iterations: 100 });
var decrypt = CryptoJS.AES.decrypt(encrypted, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 });
return decrypt.toString(CryptoJS.enc.Utf8);
}
