At HEXSSL, we are introducing a new dedicated section — SSL Tools — designed to help customers and system administrators quickly and accurately manage processes related to SSL/TLS certificates.
We have just released the first two professional tools:
🔹 CSR Generator (Certificate Signing Request)
🔹 CSR Checker (CSR Verifier)
This is just the beginning of a comprehensive toolkit that will be gradually expanded over the coming weeks — including SSL Checker, SSL Expiry Monitor, SSL Decoder, and OCSP/CRL Validator.
The new HEXSSL CSR Generator is a fully automated tool that enables the creation of Certificate Signing Requests (CSR) without the need to use a server console.
It was designed for administrators, developers, and hosting companies who need a reliable and quick way to generate a valid CSR file with a private key.
🔍 Features:
Generate CSR for single and multi-level domains (e.g., example.com, www.example.com, mail.example.com)
Full support for SAN (Subject Alternative Names) fields
Option to choose RSA key length (2048 / 4096 bit) or ECDSA (P-256 / P-384)
Automatic validation of CN, O, OU, L, ST, and C fields
Private key encryption using OpenSSL algorithms
Automatic ZIP file generation containing both CSR and private key
Compatibility with major CAs: DigiCert, Sectigo, Certum, GoGetSSL, Thawte, GeoTrust, RapidSSL, and others
⚙️ Advantages:
No SSH or control panel access required
Instant CSR generation in the browser — no login needed
Fully compliant with the latest CA/B Forum requirements
Modern, intuitive interface matching the HEXSSL style
🔍 2. CSR Checker – instant CSR analysis
The second tool released is the CSR Checker, which allows you to verify the content of any CSR file in just a few seconds before submitting it to a Certificate Authority.
🧠 Tool functions:
Automatic reading and decoding of CSR content
Display of all key details: CN (Common Name), SAN, O, OU, L, ST, C, Email, signature algorithm, and key length
Detection of syntax errors and invalid fields
Support for PEM / Base64 encoded files
Validation of compatibility with DV / OV / EV certificate requirements
✅ Use cases:
Verify CSR before submission to a CA (eliminates common issuance errors)
Check organizational data accuracy (for OV/EV certificates)
Confirm key length and algorithm type
Analyze CSRs generated on external systems (e.g., IIS, cPanel, Plesk)
🔒 Security and privacy
All HEXSSL tools are developed in accordance with the highest security standards.
No data entered into the forms (CSR, keys, organization details) is transmitted or stored on HEXSSL servers — all operations are performed locally in the user’s browser or via secure HTTPS connection. This ensures full control over cryptographic keys, and the entire process of generating and verifying CSR files strictly follows the security by design principle.
🚀 What’s next?
In the coming weeks, the SSL Tools section will be expanded with additional functionalities, including:
🔸 SSL Checker – complete certificate and chain validation
The SSL Tools section represents another step in the development of the HEXSSL ecosystem, combining professional SSL certificate offerings, diagnostic tools, and expert knowledge in one platform. This ensures that customers not only receive the best pricing and technical support but also access to practical, secure, and reliable solutions for everyday SSL/TLS management.
