Abstract
Pertukaran dokumen di dunia maya sudah banyak digunakan dalam transaksi pada saat ini. Dokumen tersebut harus dijamin oleh setiap pengguna. Untuk menjaga kerahasiaan informasi, terutama untuk isi informasi yang seharusnya diketahui hanya pihak berwenang. Pengiriman data atau informasi tanpa jaminan apapun akan beresiko terhadap penyadapan dan informasi di dalamnya dapat dengan mudah diidentifikasi oleh pihak yang tidak berwenang. Salah satu cara untuk mengamankan dokumen adalah dengan menggunakan algoritma kriptografi. Prinsip keamanan dokumen ini adalah bagaimana sistem dapat mengamankan penyimpanan dan pengiriman dokumen dengan menggunakan algoritma kombinasi. Dalam penelitian ini, penggunaan algoritma kombinasi adalah kombinasi algoritma MD5, RSA dan RC4. Tahapan dokumen keamanan mencakup tiga tahap: proses keamanan data, kunci keamanan, dan menguji integritas dari file.

- Copyright to the manuscripts of scientific papers in this Journal is held by the author.
- The author surrenders the rights when first publishing the manuscript of his scientific work and simultaneously the author grants permission / license by referring to the Creative Commons Attribution-ShareAlike 4.0 International License to other parties to distribute his scientific work while still giving credit to the author and the Journal of Information Systems and Computer Science as the first publication medium for the work.
- Matters relating to the non-exclusivity of the distribution of the Journal that publishes the author's scientific work can be agreed separately (for example: requests to place the work in the library of an institution or publish it as a book) with the author as one of the parties to the agreement and with credit to sJournal of Information Systems and Computer Science as the first publication medium for the work in question.
- Authors can and are expected to publish their work online (e.g. in a Repository or on their Organization's/Institution's website) before and during the manuscript submission process, as such efforts can increase citation exchange earlier and with a wider scope.
