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

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 PasswordDeriveBytes(
	byte[] password,
	byte[] salt,
	string hashName,
	int iterations,
	CspParameters cspParams
)

Parameters

password
Type: System.Byte[]

The password to derive the key for.

salt
Type: System.Byte[]

The key salt to use to derive the key.

hashName
Type: System.String

The hash algorithm to use to derive the key.

iterations
Type: System.Int32

The iteration count to use to derive the key.

cspParams
Type: System.Security.Cryptography.CspParameters

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 Ildasm.exe (IL Disassembler), a hex editor, or by simply opening up the assembly in a text editor such as Notepad.exe.

For a list of hash algorithm names, see the CryptoConfig class.
