Question

我有VB.Net方法可以做到这一点：

' Step 1: UTF8 Encodes
Dim uEncode As New UnicodeEncoding()

' Step 2: Creates Byte Array from UTF8 encoded string
Dim bytClearString() As Byte = uEncode.GetBytes(ClearString)

' Step 3: Creates the hash from the byte array
Dim sha As New System.Security.Cryptography.SHA256Managed()
Dim hash() As Byte = sha.ComputeHash(bytClearString)

' Base64 Encodes the hash
Return Convert.ToBase64String(hash)

在PHP中，我这样做：

// Step 1 utf8 encode
$tohash = utf8_encode('testinfostring');

// Step 2 cast string to byte array
Not sure about this step...

// Step 3
$hash = hash('sha256', $tohash, true);

// Step 4 convert hashed array to base64 encoded string
echo base64_encode($hash);

我的VB.Net方法的输出与PHP不同，我认为VB加密发生在字节数组上，而PHP在字符串本身上。

非常感谢任何帮助！

解决方案是改变PHP：

$tohash = utf8_encode('testinfostring');

为：

$tohash = mb_convert_encoding('testinfostring', 'UTF-16LE', 'UTF-8');

Vb.Net 256哈希到PHP 256哈希
