Résumé :	In today’s digital era, ensuring the security and integrity of sensitive corporate documents is of paramount importance. Unauthorized access or modifcation of such documents can have severe consequences for organizations. In our project we try to implement a robust digital signing system that employs asymmetric cryptography, quick response codes, and hash functions to safeguard sensitive corporate documents and prevent unauthorized modifcations reliably. The proposed system leverages the power of asymmetric cryptography to provide secure communication channels between document signers and recipients. The system generates a unique digital signature for each document using the private key, ensuring its authenticity and integrity. To enhance the usability and accessibility of the system, quick response codes are employed as a convenient method for document verifcation. Each signed document contains a quick response code representation of its digital signature, allowing recipients to easily verify its authenticity and integrity using a mobile device or dedicated software.
