将TripleDESCryptoServiceProvider转换为javax.crypto.Cipher

Question

我正在尝试将加密方法从VB转换为Kotlin，但是结果不一样。在vb中，它的实现方式如下：

Public Shared Function MD5Hash(ByVal value As String) As Byte()
    Dim byteArray() As Byte = ASCIIEncoding.ASCII.GetBytes(value)
    Return MD5.ComputeHash(byteArray)
End Function

Public Shared Function Encrypt(ByVal stringToEncrypt As String) As String
    Dim FvaRetorno As String = ""
    Try
        TripleDES.Key = MD5Hash(key)
        TripleDES.Mode = CipherMode.ECB

        Dim Buffer As Byte() = ASCIIEncoding.ASCII.GetBytes(stringToEncrypt)
        FvaRetorno = Convert.ToBase64String(TripleDES.CreateEncryptor().TransformFinalBlock(Buffer, 0, Buffer.Length))
    Catch ex As Exception
    End Try
    Return FvaRetorno
End Function

这是我在Kotlin中的代码：

var ALGO = "DESede/ECB/PKCS7Padding"

fun getSecreteKey(secretKey: String): SecretKey {
    val md = MessageDigest.getInstance("MD5")
    val digestOfPassword = md.digest(secretKey.toByteArray(charset("ascii")))
    val keyBytes = Arrays.copyOf(digestOfPassword, 24)
    return SecretKeySpec(keyBytes, "DESede")
}

fun encrypt(message: String, secretKey: String): String {
    val cipher = Cipher.getInstance(ALGO)
    cipher.init(Cipher.ENCRYPT_MODE, getSecreteKey(secretKey))

    val plainTextBytes = message.toByteArray(charset("ascii"))
    val buf = cipher.doFinal(plainTextBytes)
    val base64Bytes = Base64.encode(buf, Base64.DEFAULT)
    return String(base64Bytes)
}

我在做什么错了？
