How cryptography algorithm works

WebIn cryptography, the simple XOR cipher is a type of additive cipher, an encryption algorithm that operates according to the principles: . A 0 = A, A A = 0, A B = B A, (A B) C = A (B C), (B A) A = B 0 = B,. For example where denotes the exclusive disjunction (XOR) operation.

WebIf we examine the Euclidean Algorithm we can see that it makes use of the following properties: GCD (A,0) = A. GCD (0,B) = B. If A = B⋅Q + R and B≠0 then GCD (A,B) = GCD (B,R) where Q is an integer, R is an integer … WebA cryptographic algorithm is the mathematical equation used to scramble the plain text and make it unreadable. They are used for data encryption, authentication and digital signatures. There are three types of cryptography: Symmetric-key cryptography - Both sender and receiver share a single key and the sender uses this key to encrypt plaintext.

Web15 de jul. de 2003 · Because Blowfish is a symmetric algorithm, the same procedure is used for decryption as well as encryption. The only difference is that the input to the encryption is plaintext; for decryption, the input is ciphertext. The P-array and S-array values used by Blowfish are precomputed based on the user's key. WebThe Algorithm The Euclidean Algorithm for finding GCD (A,B) is as follows: If A = 0 then GCD (A,B)=B, since the GCD (0,B)=B, and we can stop. If B = 0 then GCD (A,B)=A, since the GCD (A,0)=A, and we can …
