In DevOps environments, server administration, application integration or service migration, the need for fast and reliable SSL/TLS certificate conversion between different formats appears very frequently. Various servers and applications require different file structures – Apache prefers PEM, Windows IIS uses PFX, Java/Kafka require P7B, and many network appliances only support DER.
In HEXSSL, we continuously expand our suite of tools supporting administrators, IT specialists, security auditors, and website owners in quickly diagnosing and verifying elements of the SSL/TLS infrastructure.
For the past decade, the development of network cryptography has progressed in an evolutionary manner. We updated OpenSSL libraries, replaced SHA-1 with SHA-256, increased RSA key lengths, but all of this remained within a familiar security model. In 2025, for the first time in more than 20 years, we are facing a change that is […]
SSL/TLS certificate is a key security element for every website. It ensures the encryption of data transmitted between the browser and the server and gives users confidence in your domain. However, even the best-configured certificate loses its value the moment it expires – and a single day of delay can lead to:
NIS2 is a directive that in many organizations has been perceived primarily as a procedural requirement: policies, registers, classifications, audits. Meanwhile, its real impact is much deeper – true compliance begins only at the level of cryptography. This is where the directive expects proof that the organization understands modern threats and can maintain technical security […]
The new HEXSSL SSL Checker tool enables a full analysis of an SSL/TLS certificate for any domain in real time. Simply enter the website address and the system will automatically retrieve data from the active HTTPS connection and present the results in a clear report.
In recent years, the way we generate CSR (Certificate Signing Request) has undergone a revolution. A few years ago, a CSR was one of the least problematic elements of the certificate issuance process – a simple text file in which you entered a domain, optionally the company details, generated a key, and that was it. […]
Organizational project OWASP (Open Web Application Security Project) has for many years published the Top 10 list of the most critical web application security risks. It serves as a key reference point for developers, auditors, DevSecOps operations, and IT departments. The version OWASP Top 10 2021 has been widely adopted and is becoming a foundation […]
From us: With this article, we begin a new series of publications on our website: HEXSSL Insight. These will be extensive articles containing our expertise supported by numerous examples from our own experience. We hope that the information contained in these articles will help you better understand all aspects related to broadly defined online security. […]
With the end of October, celebrated worldwide as Cybersecurity Awareness Month, we summarize HEXSSL’s initiatives promoting cybersecurity and digital resilience. The year 2025 clearly demonstrates that online security is no longer the domain of IT departments alone – it has become a key element of every organization’s business strategy, regardless of size.
