Node 中的 C# HMAC Sha256 等价物
C# HMAC Sha256 equivalent in Node
我正在尝试将 C# 应用程序移植到 Node.js 中。
该应用程序具有此 C# 函数来生成 Sha256
public static string CreateSHA256Signature(string targetText)
{
string _secureSecret = "E49756B4C8FAB4E48222A3E7F3B97CC3";
byte[] convertedHash = new byte[_secureSecret.Length / 2];
for (int i = 0; i < _secureSecret.Length / 2; i++)
{
convertedHash[i] = (byte)Int32.Parse(_secureSecret.Substring(i * 2, 2), System.Globalization.NumberStyles.HexNumber);
}
string hexHash = "";
using (HMACSHA256 hasher = new HMACSHA256(convertedHash))
{
byte[] hashValue = hasher.ComputeHash(Encoding.UTF8.GetBytes(targetText));
foreach (byte b in hashValue)
{
hexHash += b.ToString("X2");
}
}
return hexHash;
}
Response.Write(CreateSHA256Signature("TEST STRING"));
// returns 55A891E416F480D5BE52B7985557B24A1028E4DAB79B64D0C5088F948EB3F52E
我尝试如下使用节点加密:
console.log(crypto.createHmac('sha256', 'E49756B4C8FAB4E48222A3E7F3B97CC3').update('TEST STRING', 'utf-8').digest('hex'))
// returns bc0a28c3f60d323404bca7dfc4261d1280ce46e887dc991beb2c5bf5e7ec6100
如何在节点中获得相同的 C# 结果?
您的密钥与 C# 版本不同。尝试将十六进制字符串转换为原始字节。这样 crypto 就知道使用字节而不是实际的字符串。
例如:
var crypto = require('crypto');
var key = Buffer.from('E49756B4C8FAB4E48222A3E7F3B97CC3', 'hex');
console.log(crypto.createHmac('sha256', key).update('TEST STRING').digest('hex'))

message = message.encode()
return hmac.new(byte_key, message, hashlib.sha256).hexdigest().upper()
