Michał Trojnara

Michał Trojnara maintains a focused open-source security toolkit whose headline utility, Stunnel, wraps legacy TCP protocols inside modern TLS tunnels so that unencrypted mail, database, or IoT traffic can traverse hostile networks without touching application code. The same repository also supplies osslsigncode, a command-line Authenticode signer that lets developers timestamp and certify Windows PE, MSI, and Java CAB binaries using OpenSSL instead of Microsoft’s proprietary stack, and torget, a lightweight downloader that fetches multi-gigabyte files over the Tor network while minimising circuit churn and exit-node load. Together the three projects serve administrators who retrofit encryption, developers who release signed Windows installers, and researchers who need verifiable anonymity for large data transfers. The code is portable across POSIX and Windows, compiles cleanly under MinGW or MSVC, and is routinely integrated into CI pipelines for containerised mail relays, nightly build farms, and privacy-centric mirror networks. All packages are governed by permissive licences and evolve through public GitHub commits, with binary releases cryptographically signed by the author. The publisher’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the latest upstream version, and can be queued for unattended batch installation.
