What is serialization?

Serialization is the process of converting an object into a stream of bytes. De-serialization is the opposite process of creating an object from a stream of bytes. Serialization/De-serialization is mostly used to transport objects (e.g. during remoting), or to persist objects (e.g. to a file or database). There are two separate mechanisms provided by the .NET class library for serialization - XmlSerializer and SoapFormatter and BinaryFormatter. Microsoft uses XmlSerializer for Web Services, and uses SoapFormatter/BinaryFormatter for remoting.

How do I calculate a MD5 hash from a string?

It is a common practice to store passwords in databases using a hash. MD5 (defined in RFC 1321 ) is a common hash algorithm, and using it from C# is easy. Here’s an implementation of a method that converts a string to an MD5 hash, which is a 32-character string of hexadecimal numbers. public string CalculateMD5Hash ( string input ) { // step 1, calculate MD5 hash from input MD5 md5 = System . Security . Cryptography . MD5 . Create ( ) ; byte [ ] inputBytes = System . Text . Encoding . ASCII . GetBytes ( input ) ; byte [ ] hash = md5 . ComputeHash ( inputBytes ) ; // step 2, convert byte array to hex string StringBuilder sb = new StringBuilder ( ) ; for ( int i = 0 ; i < hash . Length ; i ++ ) { sb . Append ( hash [ i ] . ToString ( "X2" ) ) ; } return sb . ToString ( ) ; } An example call: string hash = CalculateMD5Hash ( "abcdefghijklmnopqrstuvwxyz" ) ; …returns a s
