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
