Peter, I can quickly explain the authorization scheme via EDS/token: how the signature is formed, how the server verifies the certificate, and how the client interacts with the library or software. I have been working with web services and integrations for 7 years, so I will help not only to understand the principle but also to identify bottlenecks in the implementation. If needed, I can explain using your stack as an example and suggest a secure architecture.

Hello, I worked on an electronic document management system with the integration of digital signatures for a government institution, where I implemented authorization through hardware tokens and processed over 1000 signatures daily.
Are you planning to use a specific cryptographic library (for example, CryptoAPI, PKCS#11) or do you need to explore optimal options for your project?
I suggest we get in touch; I will provide you with free technical consultation and we can create a development plan + I will tell you about my team! ✨

Hello, Petro!
The task is clear — authorization via hardware digital signature/token: the client signs the data with a key, and the server verifies the signature through the appropriate library.
I have experience with JWT authorization and building client-server auth flow. I haven't specifically worked with digital signatures, but the principle is similar — signing, verification, interaction through a library. I am ready to delve into the details for your stack.

Good day.
I have experience working with cryptographic services, authorization via electronic signature, and integrating third-party APIs, so I will quickly understand the task.
I will be able to thoroughly investigate the authorization process via electronic signature/token, analyze the interaction chain between the client and server, the signing and signature verification mechanisms, as well as analyze the libraries and software used.
I enjoy working on tasks like these, where it is necessary not just to implement functionality, but to understand how it works "under the hood."
Please clarify:
— Is only analysis and documentation needed, or is further implementation required as well?
— Is there a specific electronic signature service/provider (Diia.Signature, Vchysno, ACSC, etc.) that needs to be researched?
