<?php
$pwd = "test";
$crypted = base64_encode(pack("H*", sha1(utf8_encode($pwd))));
echo("$crypted");
?>
所以我在上面得到了这个PHP代码，我正在尝试将其转换为C＃代码 . 我尝试了以下，但它没有相同的输出 .
var bytes = Encoding.UTF8.GetBytes("test");
SHA1 sha = new SHA1CryptoServiceProvider();
var result = sha.ComputeHash(bytes);
string hex = Encoding.UTF8.GetString(result, 0, result.Length);
byte[] packH = PackH(hex);
var base64String = Convert.ToBase64String(packH);
和方法：
public static byte[] PackH(string hex)
{
if ((hex.Length % 2) == 1) hex += '0';
var bytes = new byte[hex.Length / 2];
for (int i = 0; i < hex.Length; i += 2)
{
bytes[i / 2] = Convert.ToByte(hex.Substring(i, 2), 16);
}
return bytes;
}
因为我没有足够的声誉来回答我自己的问题，我会在这里写下答案：D
It seems that i needed to do some extra things:D
public static string Crypt(string data)
{
SHA1 sha = new SHA1Managed();
byte[] buffer = Encoding.UTF8.GetBytes(data);
byte[] computeHash = sha.ComputeHash(buffer);
string delimitedHexHash = BitConverter.ToString(computeHash);
string hexHash = delimitedHexHash.Replace("-", "");
byte[] packH = PackH(hexHash);
return Convert.ToBase64String(packH);
}
public static byte[] PackH(string hex)
{
if ((hex.Length%2) == 1) hex += '0';
var bytes = new byte[hex.Length/2];
for (int i = 0; i < hex.Length; i += 2)
{
bytes[i/2] = Convert.ToByte(hex.Substring(i, 2), 16);
}
return bytes;
}
甚至更容易
Console.WriteLine(Convert.ToBase64String(new SHA1CryptoServiceProvider().ComputeHash(Encoding.ASCII.GetBytes("root"))));

看起来在PHP版本中，在进行base64编码之前，您还在SHA1函数的输出上调用
pack.如果我正确解释PHP版本，你基本上首先对SHA1哈希的输出进行十六进制编码，然后你对十六进制编码的字符串进行Base64编码 - 这与直接编码SHA1哈希输出的Base64不同，这是C＃版本发生了什么..
