Go to top. Layout: fixed fluid. First Prev Next. My vote of 5 RajeshKumar Sugumar Apr RajeshKumar Sugumar. Its really very good Article for the upcoming Developers like me. Thanks and give us much more valuable code like this.
I'm using linq2sql database. I wanna use my password with SHA crypto service. I need this code How do you use this code in your projects? You can help me? Thank you Thanx alrsds Sep I like another cryptography article here thats in my use.
You are most welcome. My vote of 2 Henry Minute 7-Aug The code snippets require proper formatting use Copy Code tags And explain the code in the text of the article. That way you can expand on the information given in the comments. This looks like it will be a good article, if the changes suggested by everybody are implemented. Good work Md. Hi, This is nice, I think you need to do some little bit of work Code formation for approving My vote of 2 Dave Kreskowiak 6-Aug Write toEncrypt, 0, toEncrypt.

Pavel Belousov Pavel Belousov 1, 2 2 gold badges 14 14 silver badges 21 21 bronze badges. Your IV use is incorrect. The whole point of an IV is to be different for each encryption. Don't use a constant IV. I had to convert the string to base64 string first stackoverflow.

No benefit, other than the fact that it is easier to store, to treat as a string, and if you need to move it around I find it easier.
I am not a fan of using blobs, mainly because I spent so long on mysql where they really didn't have support, so I just think that way. Besides, if you want to print out the encrypted message then it is in a printable fashion, which can be handy, just to see what happened. Good point Jrud Jrud 3 3 gold badges 7 7 silver badges 21 21 bronze badges. I know, right? I feel his pain. The only reason I knew that about access is because I was dealing with a project at my job that used an old access Database.
It was already being up-converted at the time, but that didn't stop the customers from requesting new features of the old version. Key reuse is an absolutely deadly sin with stream ciphers. Makes them really easy to break. Jeet Poria Jeet Poria 23 6 6 bronze badges. When the user sets their password, hash it, and store the hash and salt. Rijndael symmetric encryption algorithm. We will be Encrypting the string to an array of bytes and then decrypting bytes into string again. Intially, we will pass 'key' and 'Initialization vector' to create Rijndael object and create the stream to encrypt the text.
NET Framework, this algorithm supports block sizes of , , or bits, defaulting to bits. This one is the easy method, if you want to encrypt and decrypt file using same account, then you can use FileInfo. Encrypt and FileInfo. The Decrypt method decrypts an encrypted file only account that has encrypted a file can decrypt a file.
