IMPLEMENTASI KRIPTOGRAFI UNTUK KEAMANAN DATA MENGGUNAKAN AES (Studi Kasus Baitul Maal wat-Tamwil Al Ittihad Kota Pekanbaru)

The issue of security and confidentiality of data and information is an important matter. One way to maintain the security andconfidentiality of data and information is by encryption and decryption techniques, also known as cryptography.Cryptography is the science and art of maintaining message security by turning it into a form that cannot be recognizedanymore. One cryptographic algorithm that is often used today is Rijndael or also known as AES (Advanced EncryptionStandard). Cryptography can be applied to various types of files, one of which is a customer data document. The software tobe built is encryption and decryption software with the Rijndael algorithm for customer data documents. The results of thisstudy are: applications that are designed to meet information security needs, both protection of the confidentiality ofinformation and protection against falsification and alteration of unwanted informatio
