✨ OPENSSL-VERSION 💅

okay so bestie, welcome to openssl-version — it lives in the 1ossl manual section, and honestly? it's the icon of "just tell me what's going on with my OpenSSL." 🎀

🦋 NAME

openssl-version — print OpenSSL version information. literally that's the whole job and she does it slayfully ✨

🌸 SYNOPSIS

openssl version [-help] [-a] [-v] [-b] [-o] [-f] [-p] [-d] [-e] [-m]
[-r] [-c] [-w]

💖 DESCRIPTION

This command is used to print out version information about OpenSSL. no cap, that's it — she prints the tea about your OpenSSL build and dips 💅

👑 OPTIONS

  • -help — prints out a usage message, because sometimes we all need a little reminder of who we are 🫶
  • -a — all information, bestie. this is the same as setting all the other flags — one button, everything, main character energy ⭐
  • -v — the current OpenSSL version. the classic. the icon 🎀
  • -b — the date the current version of OpenSSL was built 🗓️
  • -o — option information: various options set when the library was built 🔧
  • -f — compilation flags 🚩
  • -p — platform setting 💻
  • -d — OPENSSLDIR setting 📁
  • -e — ENGINESDIR settings ⚙️
  • -m — MODULESDIR settings 📦
  • -r — the random number generator source settings 🎲 (so random, so iconique)
  • -c — the OpenSSL CPU settings info 🧠
  • -w — the OpenSSL OSSL_WINCTX build time variable, if set. Used for computing Windows registry key names. This option is unavailable on non-Windows platforms 🪟
ngl, that last one is Windows-only, so if you're on anything else she's just not coming to the party 💀

🌈 HISTORY

okay so storytime, bestie 📖 — in OpenSSL versions prior to 3.4, OpenSSL had a limitation regarding the OPENSSLDIR, MODULESDIR and ENGINESDIR build time macros. These macros were defined at build time, and represented filesystem paths. This is common practice on unix like systems, as there was an expectation that a given build would be installed to a pre-determined location. On Windows however, there is no such expectation, as libraries can be installed to arbitrary locations. OSSL_WINCTX was introduced as a new build time variable to define a set of registry keys identified by the name openssl-<version>-<ctx>, in which the <version> value is derived from the version string in the openssl source, and the <ctx> extension is derived from the OSSL_WINCTX variable. The values of OPENSSLDIR, ENGINESDIR and MODULESDIR can be set to various paths underneath this key to break the requirement to predict the installation path at build time. periodt. 💅

🧚 NOTES

The output of "openssl version -a" would typically be used when sending in a bug report. so like… if something's broken, run that, copy it, paste it, and let the maintainers cook 🔥

fr fr bestie, always include that output in a bug report — it's giving helpful 💖
