A numbers of cryptographic techniques are developed for achieving secure communication. There are basically two techniques of cryptography-Symmetric and Asymmetric. This paper presents a detailed study of the symmetric encryption techniques over each other.Keywords: Cryptography, Encryption, Decryption, AES, DES, TRIPLEDES, Blowfish.Rambabu...

Some of the cryptographic algorithms that are more recognizable to the general public are symmetric key algorithms. Several of these, such as DES, 3DES, and AES, are or have been in regular use by the U.S. government and others as standard algorithms for protecting highly sensitive data. DES...
Despite these drawbacks, however, symmetric-key cryptography does have a place in computer security. As it turns out, symmetric-key algorithms are the simplest, fastest cryptographic algorithms we know of. In a world built on bandwidth, this speed is a necessity. Symmetric-key algorithms also ...
Blowfish is a symmetric key block encryption algorithm invented by Bruce Schneier in 1993. Similar DES and AES are block encryption algorithms. Blowfish is used to replace the DES algorithm, and Blowfish has no commercial restrictions, anyone can Free to use. ...

The loss of a private key can be irreversible. When a private key is compromised, all incoming messages become unreadable. Conclusion Indeed, new algorithms are being developed to keep up with eavesdroppers and secure knowledge in order to improve secrecy. In the coming years, hackers will undoub...

Symmetric key algorithms like 3DES, AES etc operate on blocks of input data. For this to happen, the length of the input data must be exactly equal to the block length or an integral multiple of the block length for that algorithm. For example, let us take AES 128-bit encryption. L...
