I have a freshly provisioned Linux VPS and I want IceHrm up and running on it—secured, optimised and ready for daily use. Once the core installation is live, the key requirement is to enable advanced digital signing through a PKI workflow so every contract, payslip or approval generated in IceHrm can be signed and later verified. Here’s what I need from you: • Install and configure the complete IceHrm stack on the VPS (web server, PHP, database) and secure it over HTTPS. • Integrate PKI-based signing: the system must call the CA, embed the signature in each generated document and let administrators verify it from the interface. • Keep the integration upgrade-safe so future IceHrm updates won’t wipe the custom code. • Deliver concise documentation covering setup steps, how to add new user certificates and how to audit signatures. • Prove success with a short test plan: I should be able to generate a sample PDF in IceHrm, sign it using the supplied certificate and verify the signature with any standard PKI tool. Root SSH access to the VPS and existing server certificates will be supplied after award. Let me know which tools or libraries you plan to rely on—OpenSSL, phpseclib, external CA APIs, etc.—and your expected turnaround time.

Hi there, I can deploy and fully configure your IceHrm system on your Linux VPS with a secure, production-ready setup, including HTTPS, optimized server stack, and a clean, stable installation ready for daily use. I’ll also implement a robust PKI-based digital signing workflow using tools like OpenSSL/phpseclib and CA integration, ensuring documents (contracts, payslips, approvals) can be signed and verified directly within the system. The integration will be upgrade-safe, well-structured, and fully documented, including certificate management and signature verification steps. I’ll provide a clear test flow so you can generate, sign, and verify PDFs using standard PKI tools without issues. Kindly send me a message to discuss more. Thanks

Hey, I will deploy IceHrm on your VPS — web server, PHP, MariaDB, and HTTPS via Let's Encrypt — then build the PKI signing layer. For the signing workflow, I will use a custom IceHrm module that calls OpenSSL (or phpseclib) to embed X.509 signatures into generated PDFs, keeping all custom code in a separate plugin directory so core updates do not overwrite it. Questions: 1) Are you using an internal CA or a public CA for issuing user certificates? 2) Should each user hold their own signing certificate, or will one org-level certificate handle all documents? Send me a message and we can go over the details. Best regards, Kamran

Hello, I’ve read your IceHrm deployment needs end-to-end: a secure, production-ready setup on your VPS with PKI-enabled signing for every generated document. I bring 15+ years of full-stack Linux, web, and API integration experience, including PHP/MySQL stacks, OpenSSL-based security, and secure CI-friendly deployment. I’ll install IceHrm with Apache, PHP, and MySQL, harden the stack, enable HTTPS with a valid cert, and design a PKI workflow that signs PDFs and stores verifiable signatures in IceHrm. I’ll use OpenSSL for the core signing as a baseline, with phpseclib to integrate signing operations from PHP, and I can extend via external CA APIs if you prefer. The integration will be upgrade-safe by isolating the signing logic in a dedicated module and using versioned configs so future IceHrm updates don’t overwrite custom code. Deliverables include a concise deployment guide, a process to onboard new user certificates, and an audit-friendly signature verification workflow in the UI. I’ll provide a test plan: generate a sample PDF in IceHrm, sign with the supplied certificate, and verify with standard PKI tools. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. What is your preferred PKI path: use your internal CA via an API or rely on public CA integration, and do you want offline signing support in addition to online verification? Best regards, Asad

Hi there, sounds like you want IceHrm running cleanly on your VPS with a full PKI signing flow. I’ve set up similar stacks before, including custom signing layers on PHP apps, so I can handle both the install and the integration without touching core files. I’d keep it simple: • Set up Apache, PHP and MySQL, secure with HTTPS. • Install IceHrm and move all custom signing logic into an external module. • Use OpenSSL or phpseclib to generate and embed signatures. • Connect to your CA API for issuing and verifying. • Add an admin UI path for checking signatures. • Provide the docs and a short test plan. I can start right away and finish within a few days. Do you prefer the PKI calls to run synchronously in the request cycle or through a small queue for safer performance? Greetings, Slavko

Hey, IceHrm itself is a straightforward LAMP stack install, but the PKI signing integration is where the real work is, specifically building it as an upgrade-safe hook rather than a core code patch that gets wiped on the next update. I will install and configure IceHrm with Nginx, PHP, and MySQL over HTTPS, build the PKI signing integration using OpenSSL and phpseclib as a standalone plugin layer, wire it to your CA for certificate-embedded PDF signing, and deliver documentation covering setup, adding user certificates, and auditing signatures. I have built custom PHP integrations on top of open-source HR and document systems before, and always isolate custom code in override-safe plugin directories so upstream updates never touch it. Are the server certificates you plan to supply issued by an internal CA or a public one like a commercial provider, since that affects how we configure the chain of trust and whether end users can verify signatures without installing a custom root certificate?

Hi, I can deploy IceHrm on your VPS and implement a secure, upgrade safe PKI signing workflow so documents can be signed and verified reliably. I’ve worked on Linux based deployments and cryptographic integrations where stability, security, and maintainability are critical. My approach is to first set up a hardened stack using Nginx or Apache, PHP, and MySQL, with HTTPS, firewall rules, and basic server hardening. Once IceHrm is running cleanly, I’ll integrate PKI signing using OpenSSL and phpseclib, or connect to an external CA API if required. For signing, I’ll implement a modular layer that hooks into document generation, signs PDFs using certificates, and embeds signatures in a standard compliant way. Verification will be accessible from the admin side and compatible with external PKI tools. To keep everything upgrade safe, I’ll isolate custom logic into a service layer or plugin style extension without modifying core files. You’ll receive full documentation and a test flow showing generation, signing, and verification end to end. Best, Justin

Hello, I hope you are well. I read your IceHrm deployment needs and I’m confident to deliver a secure, reliable setup on your Linux VPS. I’m an independent developer with solid Linux, PHP, MySQL, and security experience, focused on clean, upgrade-safe integrations. I will install IceHrm with Apache/PHP/MySQL, harden it with HTTPS, and implement PKI-based signing so every contract, payslip, or approval is signed and verifiable from the UI. I’ll create upgrade-safe hooks so future IceHrm updates won’t wipe custom code, and deliver concise documentation covering setup steps, how to add new certificates, and how to audit signatures. A test plan will show generating a signed PDF and verifying it with standard PKI tools. I plan to use OpenSSL (with phpseclib as fallback) and can integrate an external CA API if you prefer. Turnaround: about 2-3 days after root access. Best regards, Billy Bryan

Hello, I will install IceHrm over HTTPS, build PKI signing as a custom module (upgrade-safe so updates do not wipe it), wire verification into the admin UI, plus docs and a sample-sign-and-verify test pass. For PHP PDF signing, the cleanest path is TCPDF's setSignature() with PKCS#7 byte-range insertion. Rolling with raw OpenSSL usually produces unverifiable PDFs because the placeholder math is fragile. Questions: 1) CA setup: an existing CA you call via API, or a local OpenSSL CA on the same VPS? 2) One cert per user, or a single org cert for all documents? Looking forward to talking through the details. Faizan
