I would like to share some simple functions which can encrypt and decrypt strings. These functions can be used in any of.NET Framework supporting languages. Just declare a pass phrase in your code like a master key which allows the MD5CryptoServiceProvider class (in the System.Security and System.Security.Cryptography namespace) to compute a hash value for encryption/decryption. TripleDESCryptoServiceProvider class is used to encrypt/ decrypt strings which in turn uses 3DES (Triple Data Encryption Standard) algorithm.

I try to make function for lost password in my website using vb.net the code below is fore encrypt Function getMD5Hash(ByVal strToHash As String) As String Dim. Public Function Decrypt(ByVal cipherText As String) As String Dim passPhrase As String = 'yourPassPhrase' Dim saltValue As String = 'mySaltValue' Dim hashAlgorithm As String = 'MD5' Dim passwordIterations As Integer = 2 Dim initVector As String = '@1B2c3D4e5F6g7H8' Dim keySize As Integer = 256 ' Convert strings defining encryption key characteristics into byte ' arrays.

3DES alogorithm uses three 64-bit long keys to (Encrypt-Decrypt-Encrypt) data. Declare the pass phrase as below, and you can set any string value you like: const string passphrase = ' password'; For example, 'password' is the key I used here. Now, you just have to use the Encrypt/Decrypt functions below in your class to encrypt and decrypt any string. Below are the functions. I have around 10 Years of experience using Microsoft technologies. Spyware Doctor Full Crack on this page. I started working on microsoft technologies from Visual Studio 6.0 to VS 2015. How To Re Rock Crack In A Spoon there. I have worked on both Windows and Web applications development.

I have experience of using languages and technologies such as C#, VB.Net, ASP.Net, MVC, WPF, WCF, XML Web Services, Java Script, JQuery and databases such as SQL Server, Oracle, Sybase and DB2, Also Markup languages like XML, HTML and XAML. In my leisure time I like to watch movies, play video games and read about trending technologies.

Member 2857735 3-Jan-12 9:04 3-Jan-12 9:04 This is probably the worst cryptography advice ever! For one, MD5 is quite broken, and should not be used in new code. (See rogue CA attacks because of MD5 collisions: ) Secondly, ECB is NOT a good encryption mode, it allows an attacker to replace or reorder your blocks of data, see Thirdly, triple-DES does not provide good security, according to wikipedia Triple-DES only has 80 bits of security, considering that.NET has support for far better algorithms, like AES, using ancient and broken algorithms like Triple-DES is plain stupid. Besides, one should use a key-derivation algorithm instead of just 1 round of a hash function to make brute-force and dictionary attacks against the password unfeasible. I give my vote of 1 for VERY wrong advice on a topic you are clearly not well versed on at all. Thanks for sharing the information.
