Derives a key from a password using an extension of the PBKDF1 algorithm.

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

public class PasswordDeriveBytes extends DeriveBytes

This class uses an extension of the PBKDF1 algorithm defined in the PKCS#5 v2.0 standard to derive bytes suitable for use as key material from a password. The standard is documented in IETF RRC 2898.

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) tool, a hex editor, or by simply opening up the assembly in a text editor like notepad.exe.

The following code example creates a key from a password using the PasswordDeriveBytes class.
