I will integrate encryption hashing and digital signatures in your app
Murat A
About this gig
Need encryption, hashing or digital signatures integrated into your software?
I will implement a defined cryptographic feature in your Node.js application using maintained standard libraries. My background includes low-level software, C, C++, C#, IoT and software engineering.
You receive:
- Agreed inputs, outputs and error behavior
- Integration into the specified application points
- Functional and relevant error-case tests
- Documented source code and configuration guidance
- Notes on assumptions and operational responsibilities
Basic: one hashing or signature helper.
Standard: one encryption or signing workflow and one integration point.
Premium: up to 2 related workflows and 2 integration points.
This service covers implementation. Independent security audits, compliance certification, custom cryptographic algorithms and cryptocurrency investment services are excluded. No guarantee of invulnerability is offered.
Before ordering, send your use case, runtime and interoperability requirements. Use sanitized examples and test keys; never share production secrets.

FAQ
Will you design a new encryption algorithm?
No. I integrate established cryptographic primitives through maintained libraries. Algorithm and parameter choices depend on the agreed use case and environment.
Is this a security audit or compliance certification?
No. The service covers a defined implementation and its functional tests. Independent security review, penetration testing and regulatory certification are separate services.
Do you need my private keys or production secrets?
No. Use test data and test keys. Production key creation, storage and access should stay within your controlled environment.
Do you develop cryptocurrency trading systems?
This gig focuses on cryptography within software: encryption, hashing and signatures. It does not provide trading advice or investment services.
