用於SHA512哈希的VB類型設置

Question

我有以下用於生成sha512哈希的函數。散列成功生成，但是當所得到的字符串被傳遞給其他功能引起該錯誤：

輸入字符串的不正確的格式

當調試的變量保持返回的散列（設置爲字符串）爲空。我試圖在函數和調用代碼中將類型更改爲int，int64和byte（數組和標準變量），這會導致各種其他錯誤。如何正確地更改數據類型來解決此問題？

Function create_hash(ByVal password, ByVal salt) 

Dim salty As String = password & salt 

'convert salty password to binary to feed into hash function 
Dim encText As New System.Text.UTF8Encoding() 
Dim btText() As Byte 
btText = encText.GetBytes(salty) 


'Dim data(btText) As Byte 
'create password hash 
Dim result() As Byte 
Dim shaM As New SHA512Managed() 
result = shaM.ComputeHash(btText) 

Dim return_result As String 

For Each Item As Integer In result 

    return_result = return_result & Item 

Next 



Return return_result 
End Function 

調用代碼：

Dim i_h_pass As String 
Dim i_pass As String = pass.Text 
      'handle password generation (matching passwords checked at validation) 
      Dim newHash = New hashing 
      Dim salt As String = Convert.ToString(newHash.create_salt) 
      i_h_pass = Convert.ToString(newHash.create_hash(i_pass, salt)) 

編輯：

的create_salt功能也得到了確認 - 它完美的作品，並返回一個隨機整數，返回字符串conveince

固定爲：

功能create_hash（BYVAL密碼，BYVAL鹽）

Dim salty As String = password & salt 

'convert salty password to binary to feed into hash function 
Dim encText As New System.Text.UTF8Encoding() 
Dim btText() As Byte 
btText = encText.GetBytes(salty) 


'Dim data(btText) As Byte 
'create password hash 
Dim result() As Byte 
Dim shaM As New SHA512Managed() 
result = shaM.ComputeHash(btText) 

Dim return_result As String = BitConverter.ToString(result) 
    Return return_result 
End Function 

昏暗return_result作爲字符串= BitConverter.ToString（結果）

作爲變化
