PasswordDeriveBytes Constructor (Byte[], Byte[], String, Int32, CspParameters)

Note: This constructor is new in the .NET Framework version 2.0.

Initializes a new instance of the PasswordDeriveBytes class specifying the password, key salt, hash name, iterations, and cryptographic service provider (CSP) to use to derive the key.

Namespace: System.Security.Cryptography
Assembly: mscorlib (in mscorlib.dll)

Public Sub New ( _
	password As Byte(), _
	salt As Byte(), _
	hashName As String, _
	iterations As Integer, _
	cspParams As CspParameters _
Dim password As Byte()
Dim salt As Byte()
Dim hashName As String
Dim iterations As Integer
Dim cspParams As CspParameters

Dim instance As New PasswordDeriveBytes(password, salt, hashName, iterations, cspParams)
public PasswordDeriveBytes (
	byte[] password, 
	byte[] salt, 
	String hashName, 
	int iterations, 
	CspParameters cspParams
public function PasswordDeriveBytes (
	password : byte[], 
	salt : byte[], 
	hashName : String, 
	iterations : int, 
	cspParams : CspParameters



The password to derive the key for.


The key salt to use to derive the key.


The hash algorithm to use to derive the key.


The iteration count to use to derive the key.


The cryptographic service provider (CSP) parameters for the operation.

Security noteSecurity Note

Never hard code a password within your source code. Hard-coded passwords can be retrieved from an assembly using the MSIL Disassembler (Ildasm.exe), a hex editor, or by simply opening up the assembly in a text editor such as Notepad.exe.
