Thus decryption consists of adding key stream and ciphertext (elementwise binary). MithleshArya, Mr. Dinesh Goyal … Blowfish . 10010101 00001100 11001000 In the steganography layer the system involves a PC available RGB image (PNG or BMP) decided by user to 10010111 00001110 11001011 convert its pixels into an array of binary bytes. The full list of current type number assignments is given in section 8. Setelah data rahasia sampai ke tujuan maka data ini dikembalikan ke bentuk aslinya, proses ini disebut data decryption. Embodiments of the invention relate generally to methods and systems for microprocessor data security, involving data encryption and decryption of stored data in, or in communication with, a computer microprocessor. The second value: ... (the same key is used to decrypt as to encrypt). Ilmu matematik yang mendasari teknik enkripsi dan dekripsi disebut kriptologi sedangkan teknik dan sains dari proses enkripsi-dekripsi disebut kriptografi. RC4 & OTHERS . ...
