Abstract: Manual filing activities are carried out every day and sometimes it is difficult to find back documents that have been archived so that it requires a Letter archive application. The application makes it easy to collect data, archive, and search for archived letter documents. This research focuses on developing a letter archive application by implementing the AES-256 algorithm in securing letter archive files. Advanced Encryption Standard (AES) is a cryptographic algorithm that can be used to secure data. The AES algorithm is a symmetric blockchipertext that can encrypt and decrypt information. The AES algorithm uses cryptographic keys of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits. So that the AES-256 algorithm can be implemented on the current system, the help of native libraries from the go programming language is used, namely crypto/cipher and crypto/aes so that the encryption and decryption process can be applied to the letter archive file that will be archived into the application. By doing system development on the letter archive application that is currently running, it can provide a sense of trust and security to users and produce a safer archiving system than before.
