Cryptography, the study of secret writing, has been around for a very long time, from simplistic techniques to sophisticated mathematical techniques no matter what the form however, there are some underlying things that must be done - encrypt the message and decrypt the encoded message. This free computer science essay on essay: performance analysis of steganography algorithm using security application is perfect for computer science students to use as an example. Figure 11 encryption and decryption cryptography can be strong or weak cryptographic strength can be measured in the time it takes for one to recover the plaintext the result of strong cryptography is a ciphertext that is very difficult to decipher without possession of the proper decoding tools. Introduction to encryption and decryption information technology essay chapter 1 introduction history encryption as provided in [27] is a process of converting messages, information, or data into a form unreadable by anyone except the intended recipient. Another encryption layer the process of decryption takes ciphertext and transforms it back into the original plaintext cryptanalysis in efforts to remain secure .

Cryptography is the science or study of techniques of secret writing and message hiding (dictionarycom 2009) cryptography is as broad as formal linguistics which obscure the meaning from those without formal training it is also as specific as modern encryption algorithms used to secure transactions made across digital networks. On the other hand, the asymmetric model is such that there is a pair of keys one would be for encryption, and the other for decryption in light of that, it goes to logic that the more secure model would be the asymmetric model, where the decryption key is called the ‘private key’ and the encryption key is the ‘public key’ (garloff, 2000).

Cryptography is used for the protection of all data stored on the organisation's networks and servers as explained by juels (2003) cryptography involves the encryption of data or their rendition into secret, indecipherable code, for the explicit prevention of their interpretation and use if they are accessed without the proper authorization. Cryptography is the process of hiding the real meaning of a message through a pre-determined code that is only known to the person encrypting and decrypting a message different forms of cryptography can be seen in our everyday life from the word puzzle in daily newspapers to secretaries writing in short hand. Get started paper , order, or assignment requirements we are going to be creating a basic encryption/decryption function the principle function we are writing will call an encrypt function and/or a decrypt function.

Symmetric key encryption is a type of encryption that makes use of a single key for both the encryption and decryption process some of the encryption algorithms that use symmetric keys include: aes (advanced encryption standard), blowfish, des (data encryption standard), triple des, serpent, and twofish. 11 an introduction to encryption and decryption, a type of cryptography encryption and decryption, a type of cryptography, refers to the process of scrambling information so that the observer cannot be detecting the data cryptographic key is a piece of data used to encrypt or decrypt to plaintext. Encryption is the process of transforming text into an unintelligible form called cipher data encryption is the process used to hide the true meaning of data reversing the process of encryption is called decryption encryption and decryption comprise the science of cryptography as it is applied to the modern computer.
