Abstract

Seiring dengan perkembangan informasi yang terus meningkat salah satunya penggunaan komputerisasi dalam berbagai bidang. Hal ini erat kaitannya dengan penggunaan password dalam area komputerisasi. Rawannya manupulasi password dinilai sebagai hal yang perlu dicegah menggunakan data hiding. Salah satu teknik dalam data hiding yaitu Kriptografi. Dalam kriptografi terdapat banyak algoritma, salah satnya yang memiliki kehandalan yaitu algoritma blowfish. Sampai saat ini algoritma Blowfish belum ditemukan kelemahan yang berarti hanya adanya weak key dimana dua entri dari S-box mempunyai nilai yang sama. Belum ada cara untuk mengecek weak key sebelum melakukan key expansion, tetapi hal ini tidak berpengaruh terhadap hasil enkripsi. Hasil enkripsi dengan algoritma Blowfish sangat tidak mungkin dan tidak praktis untuk di terjemahkan tanpa bantuan kunci. Sampai kini belum ada Cryptanalysis yang dapat membongkar pesan tanpa kunci yang enkripsi oleh Blowfish. Hasil pengujian menunjukkan bahwa aplikasi bisa menjalankan fungsi-fungsi untuk melakukan proses enkripsi dan dekripsi data dengan baik. Waktu proses untuk enkripsi dan dekripsi untuk masing-masing file mempunyai sedikit perbedaan dikarenakan ukuran antara plainteks dan cipherteks juga berbeda, sedangkan waktu yang diperlukan juga lebih lama. Penelitian ini telah menghasilkan aplikasi enkripsi password yang telah diuji coba dan algoritma blowfish terbukti handal dalam mengamankan password.

Abstract

Batik is one of the cultural arts recognized worldwide as a human heritage for oral and non-material culture by UNESCO since October 2009. It is known that in antiquity, the batik was a garment thatworn by relatives of the royal palace and not to be worn by commoners, even some patterns or motifs of batik can only be worn by certain groups because it has philosophical values and is used in traditional ceremonies. In Indonesia, batik has existed since the Majapahit era and was very popular in the following century. Until the 20th century all batik produced was written batik, which was only known as stamped batik. Therefore, batik is one of the cultural arts heritage that should be preserved and developed. The feature implemented in this application is a chatbot where the chatbot will provide messages containing information about batik motifs from each province in Indonesia. This application is also equipped with several features on the website, namely the home feature, the Indonesian batik feature, the historical feature that discusses the history of batik, and the chatbot feature.

Abstract

The rapid evolution of information and communication technology has revolutionized how we communicate and share information. Despite the numerous benefits, these advancements have introduced challenges, particularly concerning data security and privacy. Issues like data interception and escalating file sizes necessitate effective solutions. Cryptography emerges as a pivotal tool in addressing these concerns, offering a means to bolster data security while mitigating file size. This field encompasses the science and techniques of information security, converting data into unreadable ciphertext through encryption algorithms and keys. Encryption, particularly end-to-end encryption, plays a crucial role in maintaining confidentiality during file storage and exchange. The RSA cryptographic algorithm exemplifies an asymmetric approach, utilizing distinct keys for encryption and decryption. Public and private keys ensure secure communication, with the public key encrypting messages and the private key decrypting them. This widely adopted algorithm fortifies data security across various applications. Complementing this, the Caesar Cipher, a simple substitution cryptographic technique, adds an additional layer to the encryption process. By replacing each character with another at a specified shift in alphabetical order, the Caesar Cipher offers a basic yet effective safeguard. Combining the robust RSA algorithm with the simplicity of Caesar Cipher enhances file storage security. Employing Caesar Cipher as the initial step in encryption, followed by RSA to encrypt its output, ensures double-layered encryption. This dual process guarantees that only the corresponding private key can decrypt the file, reinforcing the overall security of data storage and exchange.
