小写十六进制字符。NET和Java等价物

一个贸易伙伴要求我将HMAC SHA1散列作为小写的heaxit发送。我能找到的唯一参考资料是关于PHP的。我可以在.NET和Java中进行哈希运算，但是如何用它们输出“小写的十六进制数”？小写的十六进制看起来并不等同于Base64

对于小写十六进制数字（hexits），请使用：

公共静态字符串toHex（字节[]字节）{
BigInteger bi=新的BigInteger（1，字节）；
返回字符串.格式（“%0”+（bytes.length）对于小写十六进制数字（hexits）使用：

公共静态字符串toHex（字节[]字节）{
BigInteger bi=新的BigInteger（1，字节）；
返回字符串.格式（“%0”+（bytes.length）对于小写十六进制数字（hexits）使用：

公共静态字符串toHex（字节[]字节）{

返回String.format（“%0”+（bytes.length啊！我喜欢简单。下面是解决方案

Public Shared Function Encrypt(ByVal plainText As String, ByVal preSharedKey As String) As String
    Dim preSharedKeyBytes() As Byte = Encoding.UTF8.GetBytes(preSharedKey)
    Dim plainTextBytes As Byte() = Encoding.UTF8.GetBytes(plainText)
    Dim hmac = New HMACSHA1(preSharedKeyBytes)
    Dim cipherTextBytes As Byte() = hmac.ComputeHash(plainTextBytes)

    Dim strTemp As New StringBuilder(cipherTextBytes.Length * 2)
    For Each b As Byte In cipherTextBytes
        strTemp.Append(Conversion.Hex(b).PadLeft(2, "0"c).ToLower)
    Next
    Dim cipherText As String = strTemp.ToString
    Return cipherText
End Function

这与PHP hash_hmac函数兼容，原始输出参数为FALSE。
啊！我喜欢简单。下面是解决方案

Public Shared Function Encrypt(ByVal plainText As String, ByVal preSharedKey As String) As String
    Dim preSharedKeyBytes() As Byte = Encoding.UTF8.GetBytes(preSharedKey)
    Dim plainTextBytes As Byte() = Encoding.UTF8.GetBytes(plainText)
    Dim hmac = New HMACSHA1(preSharedKeyBytes)
    Dim cipherTextBytes As Byte() = hmac.ComputeHash(plainTextBytes)

    Dim strTemp As New StringBuilder(cipherTextBytes.Length * 2)
    For Each b As Byte In cipherTextBytes
        strTemp.Append(Conversion.Hex(b).PadLeft(2, "0"c).ToLower)
    Next
    Dim cipherText As String = strTemp.ToString
    Return cipherText
End Function

这与PHP hash_hmac函数兼容，原始输出参数为FALSE。

这与PHP hash_hmac函数兼容，在raw_输出参数中为FALSE。
这里是sedge解决方案的C翻译：

private static String toHex(byte[] cipherTextBytes)
{
    var strTemp = new StringBuilder(cipherTextBytes.Length * 2);

    foreach(Byte b in cipherTextBytes) 
    {
        strTemp.Append(Microsoft.VisualBasic.Conversion.Hex(b).PadLeft(2, '0').ToLower());
    }

    String cipherText = strTemp.ToString();
    return cipherText;
}

下面是莎草解决方案的C#翻译：

private static String toHex(byte[] cipherTextBytes)
{
    var strTemp = new StringBuilder(cipherTextBytes.Length * 2);

    foreach(Byte b in cipherTextBytes) 
    {
        strTemp.Append(Microsoft.VisualBasic.Conversion.Hex(b).PadLeft(2, '0').ToLower());
    }

    String cipherText = strTemp.ToString();
    return cipherText;
}

感谢堆。有人知道如何在.NET 3.5中做到这一点吗？BigInteger仅在4中引入.NET。非常好！谢谢！感谢堆。有人知道如何在.NET 3.5中做到这一点吗？BigInteger仅在4中引入.NET。非常好！谢谢！感谢堆。有人知道如何在.NET 3.5中做到这一点吗？BigInteger仅在4.0中引入.NET。非常好用！谢谢！感谢堆。有人知道如何在.NET 3.5中实现这一点吗？BigInteger仅在4.0中引入.NET。非常好用！谢谢！
