Cryptographic Algorithms For VB.NET

I wanted to share some Cryptographic Algorithms with you all and by the way cryptographic is a very important resource for programmers all the way .

Triple DES - triple data encryption (3DES)

Imports System.Text
Imports System.Security.Cryptography

Public Class 3_DES
    Public Shared Function Encrypt(ByVal toEncrypt As String, ByVal key As String, ByVal useHashing As Boolean) As String
  Dim keyArray As Byte()
  Dim toEncryptArray As Byte() = UTF8Encoding.UTF8.GetBytes(toEncrypt)

  If useHashing Then
    Dim hashmd5 As New MD5CryptoServiceProvider()
    keyArray = hashmd5.ComputeHash(UTF8Encoding.UTF8.GetBytes(key))
  Else
    keyArray = UTF8Encoding.UTF8.GetBytes(key)
  End If

  Dim tdes As New TripleDESCryptoServiceProvider()
  tdes.Key = keyArray
  tdes.Mode = CipherMode.ECB
  tdes.Padding = PaddingMode.PKCS7

  Dim cTransform As ICryptoTransform = tdes.CreateEncryptor()
  Dim resultArray As Byte() = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length)

  Return Convert.ToBase64String(resultArray, 0, resultArray.Length)
    End Function
End Class
