For this reason, legal issues relating to encryption, deciphering and codebreaking become increasingly topical. Due to the increased vulnerability of a wide range of people to exploitation, digitalisation implies an urgent need to develop measures for preserving privacy in digital life. Increasing vulnerabilities experienced in the social environment due to the Internet and network interactions can be attributed to the erasure of boundaries between people, which is facilitated by access to their data. In terms of providing general protection to online users, digital contracts, routine bank transfers and communications serve as an example. Cryptography, which allows the encoding of a message in an unintelligible format for those who do not have the appropriate key, represents one of the safest techniques for securely transmitting information online. In order to examine the relations between law and cryptology, the present work analyses Brazilian legal acts governing cryptography. Here, as well as defining cryptography, the main objective is to determine its main aspects and key features in order to examine the main legal issues and pecularities of legal regulation. It concludes that cryptography, as a mean to protect privacy on the Internet, does not exclude the necessity of law, but, on the contrary, legal regulation is essential to provide legal certainty to the cryptographic techniques.</p></abstract><trans-abstract xml:lang="ru"><p>В условиях постепенного сокращения ограничений в цифровой среде и исчезновения границ между физическим и виртуальным мирами значение киберпространства для повседневной деятельности людей все более увеличивается. По этой причине необходимость изучения правовых аспектов обеспечения безопасности в сети, в частности шифрования, расшифровки и взлом источников информации, становится чрезвычайно актуальным. В связи с повышенной уязвимостью большинства людей в процессе осваивания новых технологий цифровизация влечет за собой потребность в разработке средств для сохранения конфиденциальности их частной жизни. Интернет и сетевое общение сделали социальную среду более уязвимой, стерев многие границы во взаимодействии между людьми и облегчив доступ к их данным. Ярким примером необходимости охраны прав участников гражданского оборота служат ежедневное заключение договоров в Интернете, осуществление рутинных банковских переводов и ведение коммуникации в цифровом поле. Одним из средств, гарантирующих безопасность передачи информации в сети, является криптография, позволяющая зашифровать сообщение для тех, у кого нет специального ключа. В статье анализируются правовые акты Бразилии, регламентирующие криптографию, для выяснения соотношения права и криптологии. Основная цель статьи – определить, что представляет собой криптография как явление, выявить ее основные черты и особенности, чтобы отметить основные проблемы и особенности правового регулирования. В результате автор приходит к выводу, что криптография как средство защиты информации в сети не исключает необходимость правового регулирования: напротив, правовая регламентация криптографических технологий необходима для обеспечения определенности в защите прав участников оборота.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цифровое право</kwd><kwd>криптография</kwd><kwd>криптология</kwd><kwd>информационная безопасность</kwd><kwd>цифровая подпись</kwd><kwd>криптовалюта</kwd></kwd-group><kwd-group xml:lang="en"><kwd>digital law</kwd><kwd>cryptography</kwd><kwd>cryptology</kwd><kwd>information security</kwd><kwd>digital signature</kwd><kwd>cryptocurrency</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">Althabhawi, N.
