Существует несколько основных характеристик, которые отличают алгоритмы шифрования: затраченное время, эффективность шифрования данных и способность защищать данные от различных атак. В этом документе представлено сравнение между наиболее распространенными алгоритмами симметричного шифрования: DES, 3DES, Blowfish и AES. Сравнение было сделано путем обработки блоков данных разных размеров для оценки скорости шифрования и дешифрования. Поскольку нашей главной задачей является выполнение этих алгоритмов с различными настройками, представленное сравнение учитывает поведение и производительность алгоритма при использовании различных нагрузок данных. В этой статье также анализируются такие параметры как гибкость, возможность расширения ключа, возможные атаки и уязвимость алгоритмов, которая определяет эффективность криптосистемы.</p></abstract><trans-abstract xml:lang="en"><p>This article represents an equitable comparison between the most popular and frequently used algorithms in the data encryption area. There are some main characteristics that distinguish encryption algorithms: elapsed time and efficiency of data encryption and ability to protect data from various attacks. This document presents the comparison between the most common symmetric encryption algorithms: DES, 3DES, Blowfish, and AES. The comparison was done by processing data blocks of different sizes to estimate the encryption and decryption speed. Since our main task is to perform these algorithms with different settings, the presented comparison takes into account the behavior and performance of the algorithm when using different data loads. This paper also analyzes parameters such as flexibility, key extension option, possible attacks and security vulnerability of the algorithms, which determines the efficiency of the cryptosystem.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алгоритмы шифрования</kwd><kwd>криптография</kwd><kwd>AES</kwd><kwd>DES</kwd><kwd>Blowfish</kwd><kwd>TripleDES</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Encryption Algorithms</kwd><kwd>Cryptography</kwd><kwd>AES</kwd><kwd>DES</kwd><kwd>Blowfish</kwd><kwd>TripleDES</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">G.
