Simple Steganography; Encryption and Decryption of Huge Messages of Any Language
As we know, Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message. Here we hide the huge message within an image.
Cryptography in VB.NET Part 1
Learn cryptography fundamentals in .NET, including plaintext and ciphertext, symmetric and asymmetric encryption, keys, block cipher modes, initialization vectors, and padding.
Cryptography in Microsoft.NET Part I: Encryption
In this article, Gowry sheds lights on the basics of cryptography and how it can be implemented in .NET.
How Easy Cryptography is in VS.Net
What can be done regarding the security issues? Part of the solution is to secure important data - more specifically, using strong encryption thats what we will see in this article.
Cryptography in Microsoft.NET Part II: Digital Envelop and Digital Signatures
Part-I of this article covered cryptography in the context of encryption. This part continues from where part-I left. It assumes that the reader understands the purpose of encryption, knows about the two types of encryption namely asymmetric encryption and symmetric encryption and the fundamental differences between them. It also assumes that the reader understands encryption-decryption classes in System.Security.Cryptography namespace and the stream based encryption model in. NET framework class library (FCL).
How we Decrypt the Text File using DES Method in ASP.Net: Part 2
In this article we will learn how to decrypt a Encrypted text file.
Using the DPAPI through ProtectedData Class in .Net Framework 2.0
The objective of this tutorial is to show how the DPAPI can be used to encrypt and decrypt data. Encrypt some data using ProtectedData Class in System.Security.Cryptography namespace and save it to a file. Show that the data can be decrypted using the same class but deferent method. Login as a different user,and show that the data cannot be decrypted.
File Encryption
The classes in the .Net Framework cryptography namespace manage many details of cryptography for you.
Cryptography in .NET
This article gives a brief overview of Cryptography and the Cryptography support provided by the .NET Framework. I begin by introducing Cryptography and then proceed to examine the various types of it. In particular, I review and analyze the various cryptography algorithms and objects supported by .NET. I conclude after proposing and briefly discussing the algorithmic technique that would work best for you.
Symmetric Encryptor Beta1
Free to use Encrypt/Decrypt using 2 Symmetric Algorithms 'DES' and 'RC2' coded in C#.
Implementing the Chaocipher in C#
Learn how the Chaocipher works and implement its encryption and decryption algorithms in a C# console application.
Creating a Substitution Cipher with C#
I thought for a bit of fun I'd invent a new cipher and, depending on how 'strong' it turned out to be, perhaps use it in my projects to encrypt string literals, files etc.
Public Key Encryption (RSA Method) for Encryption and Decryption in ASP.Net
Learn how to encrypt and decrypt text with RSA public-key cryptography using RSACryptoServiceProvider in C# for ASP.NET applications.
Encrypt a File using DES (Data Encryption standard) Algorithm in ASP.NET
In this article we will learn how we can encrypt a file using DES (Data Encryption standard) algorithm in ASP.NET.
Cryptography in Asp.net
This article explains what is Cryptography? Why it is needed? and the types of Cryptography.
File Tampering Detection
This article describes an easy approach to determining whether or not two files are exactly the same.
