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. Symmetric algorithms are attractive due to 1000 times faster ...
for (i=0;en[i]!=-1;i++) printf("%c",en[i]); } void decrypt() { long int pt,ct,key=d[0],k; i=0; while(en[i]!=-1) { ct=temp[i]; k=1; for (j=0;j<key;j++) { k=k*ct; k=k%n; } pt=k+96; m[i]=pt; i++; } m[i]=-1; printf("\nTHE DECRYPTED...
The encrypted text cannot be decoded if the key matrix is not invertible. The key matrix employed for encryption in the Involutory matrix generation method is invertible. As a result, we do not need to find the inverse of the key matrix during decryption. 展开 ...

encryption- the activity of converting data or information into code encoding coding,steganography,cryptography,secret writing- act of writing in code or cipher compression- encoding information while reducing the bandwidth or bits required data encryption- (computer science) the encryption of data for ...
Data Decryption]]>The main objective of cryptography is to send information or message in hidden manner from one side to another in such a way that the intruder or attacker cannot crack the content and even unable to feel the presence of secret message. Although many new t...
A Symmetric Encryption Algorithm is a type of encryption algorithm that uses a single secret key for both encryption and decryption processes. It is known for its high security and fast processing speed, making it suitable for encrypting large amounts of data. ...

Basically, the common secret key represents an entry date for encryption and decryption algorithms, so not knowing its exact value will lead to the impossibility of decrypting that message by an unauthorized person. In the following, we will describe a simple symmetric cipher that can be used to...
Thus, we have a way to perform encryption then decryption, each using a different number: e in one case and d in the other. Using the RSA equation in practiceOnce we've picked values for p and q (remember, these are random large primes), we need to pick suitable corresponding values ...
