Nov 20, 2014В В· Running the application; for testing. Run the web page, enter the password as "CodeProject" you will find the following web page. Notice that there is a "False" infront of Verify, that is because we're not passing the correct Hash code for the CodeProject password to check against. Let's paste the hashed password from the result to the source If you hash on the client side, the hashed password becomes the actual password (with the hashing algorithm being nothing more than a means to convert a user-held mnemonic to the actual password).. This means that you will be storing the full "plain-text" password (the hash) in the database, and you will have lost all benefit of hashing in the first place.
