Encryption Jobs

I am completing Binance’s KYB process and their detailed security questionnaire is the last hurdle. The form dives deep into Network, Application, and Data security, yet my current posture is only at a “basic measures in place” level. I need an experienced security professional to step in, translate the questionnaire into clear action items, and guide me through every answer so it passes Binance’s review the first time. Beyond simply filling the form, I also want a concise remediation plan that closes any gaps you uncover. Expect to look at firewall rules, segmentation, secure coding practices, encryption at rest / in transit, access controls, logging, and incident-response playbooks—anything necessary to elevate those basic controls to a standard Binance wil...

I maintain a corporate-level website and need practical, hands-on coaching to tighten its security, with a clear focus on data encryption. Rather than simply handing the job over, I want to understand the rationale behind each protection layer so I can maintain and extend it confidently in the future. Here is what I’m after: • A short audit of my current server, database, and front-end setup so we know what we’re starting with. • Step-by-step guidance to implement strong encryption for data in transit (TLS configuration, HSTS, secure ciphers) and at rest (database field-level or full-disk, depending on findings). • Clear explanations of best practices—key rotation, certificate management, secrets storage, OWASP-aligned coding patterns—so I learn ...

I am building a multi-service super app and the first piece I want to nail down is a rock-solid messaging component. For this initial milestone I only need plain text chat, but it must ship with true end-to-end encryption from day one—think Signal-level security, forward secrecy, perfect message authenticity, and tamper-proof delivery receipts. I am open to whichever stack or protocol you prefer (Signal protocol, Matrix Olm, double-ratchet, etc.) as long as it is open-standard, fully audited, and can be licensed for commercial use without hidden fees. The code base should be clean, well-documented, and easy to integrate later with other services in the app, such as payments or ride-hailing. Deliverables expected: • A working Android and iOS messaging module (React Native, Flut...
