Abstract

Abstract: Combined algorithm (Cest Cryptography) is a combination of 3 algorithms such as Merklee-Hellman, Discrete Logarithm and ASCII Modification, using Base64 to hide 2 public keys and 2 private keys. Combination algorithms are used because of the increasing number of techniques in cryptography, making it easier to combine each other algorithms in order to get more complicated encryption that won't even be cracked in the near future. On large sites there has been database theft, if the stolen database has been encrypted it will be difficult for data thieves to take advantage of it, but if it is not encrypted it is very easy to use the data so that it creates huge losses, especially user trust from the site.            Keywords: algorithm combination; ascii modification; base64; merklee-hellman; discrete logarithm  Abstrak: Kombinasi algoritma (Cest Cryptography) merupakan kombinasi 3 algoritma seperti Merklee-Hellman, Logaritma Diskrit dan Modifikasi ASCII, menggunakan Base64 untuk menyembunyikan 2 kunci public dan 2 kunci private.. Kombinasi algoritma digunakan karena semakin banyaknya teknik-teknik dalam kriptografi sehingga mempermudah untuk saling mengkombinasikan algoritma agar mendapatkan enkripsi yang lebih rumit dan bahkan tidak bisa dipecahkan dalam jangka waktu dekat. Pada situs-situs besar telah terjadi pencurian database, jika database yang dicuri telah terenkripsi maka akan mempersulit pencuri data untuk memanfaatkannya tetapi jika tidak terenkripsi maka sangat mudah data tersebut di manfaatkannya sehingga membuat kerugian yang sangat besar terutama kepercayaan pengguna dari situs tersebut. Kata kunci: kombinasi algoritma; modifikasi ascii; base64; merklee-hellman;logaritma diskrit

Abstract

Technological advances have given birth to various kinds of innovations, one of which is the Hospital Management Information System (SIMRS). SIMRS is a tool in the process of making medical recaps for patients in hospitals. This is due to the daily activities of PKL (Field Work Practice) students who have to make reports about patient medical recaps.
