Good day!
We are ready to provide coding services for applying an electronic signature to data (of type bytes) using a qualified electronic signature (QES). We offer an implementation that will meet your requirements, using modern cryptographic libraries to ensure security and reliability.
What will be implemented
Data signing
Use of RSA or ECDSA algorithms (depending on your requirements).
Working with any type of data in bytes format.
… Signature verification
Ability to validate the signature using the corresponding public key.
Flexibility
Support for various libraries for cryptography (e.g., cryptography, pycryptodome).
Possibility of integration into the existing system.
Interface
Simple and understandable code with usage examples.
Technical details
Programming language: Python.
Library: cryptography (or another of your choice).
Signing algorithms: RSA (PKCS#1 v1.5 or PSS), ECDSA, DSA.
Key formats: PEM, DER.
Our experience
Development of solutions using cryptography for data protection.
Integration of digital signatures into existing business processes.
Ensuring compliance with security standards (PKCS, ISO 9796).
Benefits of collaboration
Reliable and proven code.
Flexibility in implementation depending on your requirements.
Support and maintenance after implementation.
We are ready to discuss your needs in detail and start the implementation. We look forward to your response!
