<![CDATA[The exchange of information in the digital era has become a general need for society. However, the information sent often has a public or confidential nature. Therefore, security is needed so that confidential information remains safe. Cryptography is a field of knowledge used to secure information using encryption and decryption processes. One of the cryptographic methods used is the permutation method, which changes the layout, sequence, or structure of data into a form that is difficult to understand without knowledge of the exact key. Implementing cryptography using the permutation method in Android-based applications can increase the security and privacy of user data, as well as protect sensitive information from unauthorized access. This research aims to implement permutation method cryptography in Android-based applications to protect the confidentiality or privacy of user data. By using the permutation method, the sequence of bits or characters in the data is scrambled so that it is difficult for unauthorized parties to understand. The research results show that the implementation of permutation method cryptography in Android applications can provide a higher level of security in maintaining data confidentiality. However, it is worth considering that simple permutation methods may not be secure enough to deal with more sophisticated attacks. Therefore, choosing a stronger cryptographic method needs to be considered to achieve a higher level of security. In conclusion, implementing cryptography using the permutation method in Android-based applications can increase the security and privacy of user data. The permutation method is able to randomize the sequence of bits or characters in the data so that it is difficult for unauthorized parties to understand. However, for a higher level of security, it is necessary to consider stronger cryptographic methods.]]>

<![CDATA[The management of borrowing and returning goods in government institutions is still largely carried out manually, which often gives rise to various problems, such as difficulties in tracking borrowing histories, the high risk of recording errors, and the lack of transparency regarding the availability of goods. This condition indicates the need for support from an information system that is capable of assisting the recording process and inventory management in a more structured, systematic, and easily monitored manner. This research aims to design a prototype of a goods borrowing and returning application as an initial solution to these problems as well as a preliminary representation of a system that can be further developed by the institution. The research method used is a Research and Development (R&D) approach with a prototype Software Development Life Cycle (SDLC) model, which allows system development to be carried out gradually and flexibly in accordance with user needs. Data collection was conducted through observation and interviews to obtain an overview of the ongoing work processes and to identify the required system needs. The collected data were then analyzed as the basis for designing the system workflow, data structure, and user interface design. The results of this research are in the form of an application prototype that represents the main system features, including goods borrowing, goods returning, availability checking, goods data management, and report generation.]]>

<![CDATA[The rapid expansion of internet usage has led to a significant increase in cybersecurity threats, particularly phishing attacks delivered through malicious links. Phishing links are designed to imitate legitimate websites in order to deceive users and steal sensitive information. This study presents the implementation of a phishing link detection website based on SSL validation and URL scoring mechanisms. The proposed system integrates heuristic-based URL analysis with real-time SSL certificate validation obtained through the SSL handshake process. Digital certificates are verified using RSA-based digital signature verification issued by trusted Certificate Authorities (CAs). In addition, the SHA-256 hash algorithm is employed to generate certificate fingerprints and URL hashes to ensure data integrity and uniqueness. The system also evaluates HTTPS usage, domain and certificate consistency, certificate validity period, and RSA public key strength. All validation results are processed using a URL scoring system to generate a security score ranging from 0 to 100, which classifies links into safe, suspicious, or dangerous categories. Experimental results demonstrate that the proposed website is capable of effectively identifying phishing indicators and providing transparent cryptographic evidence in real time. This approach can assist users in making informed decisions and improving protection against phishing threats in web environments.]]>
