There are two basic types of cryptography :Symmetric Key and Asymmetric key. This paper describes various encryption techniques(Substitution and transposition) with their limitations .In this paper Encryption techniques are discussed with their limitations and procedure .Huffman coding and B2G,G2B is ...
In cryptography, encryption is the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information (in ...
This is the third entry in a blog series on using Java cryptography securely. The first entry provided an overview covering. The second one covered. This entry will teach you how to securely configure basic encryption/decryption primitives. This blog series should serve as a one-stop resource f...
In the same class also fall systems that make use of perforated cardboard matrices called grilles; descriptions of such systems can be found in most older books oncryptography. In contemporary cryptography, transpositions serve principally as one of several encryption steps in forming acompoundorproduc...

Encryption has evolved significantly over time. Early instances ofcryptographyand techniques resembling encryption date back to ancient civilizations such as the Egyptians and Mesopotamians. Encryption was later popularized in wartime and espionage efforts and famously associated with the Enigma Machine, a ...
For example, “attack in three days” shifted by 5 letters would be written as “fyyfhp ns ymwjj ifdx.” Early text shift ciphers such as these proved effective until the development of text analysis techniques that could detect the use of the most commonly used letters (e, s, etc.)....
Encryption secures digital data using one or more mathematical techniques known as cryptography. The information input becomes unreadable through encryption as analgorithmconverts the original text, known as plaintext, into an alternative form known as ciphertext. When an authorized user needs to read ...
The better solution to offer the necessary protection against the data intruders is cryptography. Cryptography is the one of the main categories of computer security that converts information from its normal form into an unreadable form by using Encryption and Decryption Techniques. The Cryptography ...
