    Abstract
    Keamanan, kerahasiaan, dan ukuran data merupakan hal yang sangat penting dalam proses pengirim data. Adanya kriptografi yang dapat menjamin keamanan dan kerahasiaan data, maka data yang akan dikirimkan akan sampai kepada pihak penerima dengan aman tanpa diketahui oleh pihak yang tidak bersangkutan. Algoritma Kriptografi yang digunakan adalah algoritma Spritz, yang melakukan enkripsi satu per satu terhadap karakter atau disebut sebagai stream cipher. Adanya kompresi yang dapat mengurangi ukuran data, maka data yang ingin dikirim akan melalui proses kompresi untuk memperkecil ukuran data agar proses transfer data lebih cepat. Algoritma kompresi yang digunakan adalah algoritma Goldbach G0 Codes yang merupakan algoritma yang bersifat loseless, sehingga tidak akan ada data yang hilang setelah melalui proses kompresi. Pada penelitian ini, jenis file yang digunakan adalah file teks yang berekstensi *.txt. Rata-rata waktu yang digunakan selama proses enkripsi-kompresi adalah 0.068 ms dan proses dekompresi-dekripsi adalah 0.043. Berdasarkan parameternya, hasil dari kinerja kompresi yaitu compression ratio dengan rata-rata 65.60% dan space saving dengan rata-rata 34.40%.
     
    The safety, confidentiality, and size data are the most important things in the process of sending data. The existence of cryptography which can guarantee the safety and confidentiality of data, then the data will be sent to the recipient safely without being known by the parties that are not concerned. The cryptographic algorithm used is the Spritz algorithm, which encrypts characters one by one or is known as a stream cipher. With compression that can reduce the size of the data, so the data you want to send goes through a compression process to reduce the size of the data so that the data transfer process is faster. The used compression algorithm is the Goldbach G0 Codes algorithm which is a lossless algorithm, so that no data will be lost after going through the compression process. In this study, the type of file which is used, is a text file with the extension *.txt. The average time that is used during the encryption-compression process is 0.068 ms and the decompression-decryption process is 0.043. Based on the parameters, the results of the compression performance are the compression ratio with an average of 65.60% and space saving with an average of 34.40%.
