Implementasi Steganografi Least Significant Bit (LSB) dengan Algoritma Kriptografi Super Enkripsi pada File Citra

Abstract

Cryptography is a method to keep messages by converting them into codes. But, cryptographic results often raise suspicion. Therefore, steganography is needed to hide the message its existence is not known. Steganography is a method to hiding a message within another message so that the message is not detected. This research uses a super encryption cryptographic algorithm from a combination of 3 cryptographic algorithms Hill Cipher, Playfair Cipher, and Vigenere Cipher, and the Least Significant Bit (LSB) steganography method with random message insertion using the Pseudo Random Number Generator (PRNG) with the Linear Congruential Generators (LCG) method. The result of this research is a program that can be applied to secure text messages which are converted into codes, then inserted into an image file in JPG format
