Encrypting String in C#

Why you need to decrypt the password. It should never be decrypted for security reasons. And for encryption try these:

how to create password encrypt decrypt in c#[^]

encrypt or decrypt password in c# with asp.net[^]

hope it helps :)

Hi all,

What i understand till now is,

if we want to provide the security to passwords, then we can do it in two ways...

1. Using Hashing Concept

2. Usning Encrypting and Decrypting concepts..

Explanation:

If we want to use the Hashing then, we will use the Salt Value.

Ex Links:

Example 1[^]

Example 2[^]



If we want to use the Encryption and Decryption concept, then we should use any of the algorithms like MD5, DES . SHA etc..

Ex Links:

Encrypt/Decrypt String using DES in C#[^]

Is it correct ?. It not just guide me once....and which one is preferable(i.e either Hashing Concept or E&D Concept....

Encrypt and Decrypt Data with C#[^]

Hi Uday,
can you explain a little bit about your words
"Why you need to decrypt the password. It should never be decrypted for security reasons".

use these two function to enrypt and derypt the string
you can use C# to encrypt and decrypt strings using a salt key to protect the data.
This type of encryption is called symmetric-key encryption, which means that the string can only be decrypted if the other party has the correct key

<pre lang="c#">
