encryption - Fast and secure cryptography algorithm C#

May 27, 2006 · As you can see, CAST-128 is three times faster than a AES-256 cipher on the .NET 2.0 platform. Also, CAST-128 is two times faster than the reduced version of the Rijndael algorithm working with a 128-bit key (AES-128). It is also much faster than the unmanaged implementation of the TripleDES algorithm (by the TripleDESCryptoServiceProvider class). 7-Zip also supports encryption with AES-256 algorithm. This algorithm uses cipher key with length of 256 bits. To create that key 7-Zip uses derivation function based on SHA-256 hash algorithm. A key derivation function produces a derived key from text password defined by user. Implementing encryption yourself is a bad idea in general - in contrast to using any proper cryptographic library. I would suggest reading this article: If You’re Typing the Letters A-E-S Into Your Code You’re Doing It Wrong - and using your own encryption is a lot worse than the pitfalls mentioned there. $\endgroup$ – tylo Jun 6 '17 at 11:41 May 01, 2020 · The proposed system has the fastest encryption/decryption speed. In the proposed image cryptography, the length of key streams is only half the size of the plain image. In the schemes of Huang et al. and Diaconu, the length of key streams is greater than the size of the plain image.

If you need asymmetric encryption, use 2048-bits RSA. If you can get away with symmetric encryption, use 256-bit AES. MSDN Reference: System.Security.Cryptography RSACryptoServiceProvider AesCryptoServiceProvider. You can read about the difference between them here: Symmetric versus Asymmetric.

RSA is a public-key encryption algorithm and the standard for encrypting data sent over the internet. It also happens to be one of the methods used in PGP and GPG programs. Unlike Triple DES, RSA is considered an asymmetric encryption algorithm because it uses a pair of keys. The public key is used to encrypt a message and a private key to Definition of encryption algorithm | PCMag International Data Encryption Algorithm was produced by Xuejia Lai and James Massey. It is fairly fast, is considered secure, and it is also resistant to both linear and differential analysis.
