Cryptography a vital pole in modern information security, it ensures the confidentiality, integrity, and authenticity of digital communications. In this thesis we explore these concepts in depth, focusing on their application in creating electronically signed diplomas through a system called EDIPLOMA. The first chapter provides a comprehensive overview of cryptographic techniques and their role in secure communication. The second chapter examines the authentication mechanisms essential for verifying identities in digital transactions. Finally, the third chapter details the implementation of the EDIPLOMA system, demonstrating how cryptography and authentication combine to enhance the reliability of electronic diplomas. This work highlights the importance of secure digital signatures in educational credentials and contributes to the ongoing discourse on improving the security of digital documents.
