Aplikasi Penandatanganan Dokumen Secara Digital Menggunakan Metode Advanced Encryption Standard (Aes) (Studi Kasus: Fmipa Universitas Riau)
The legitimacy of signing soft files digitally may not be guaranteed. The goal of
this research was to create a Digital Signature Information System (esign) that
can produce a document with a valid signature and QRCode to authenticate the
document. A Digital Signature file in PKCS#12 format is required to sign a digital
document. The system was developed using PHP programming language and
CodeIgniter 4 framework. The designed system must be secure to protect user
data. Encrypting data is a technique to keep the data safe. This research used
Advanced Encryption Standard (AES-128) Counter Mode to encrypt user data.
The encryption operation was performed on digital signature file. The ciphertext
from digital signature file was saved in a file.
