💖 openssl-configutl — the OpenSSL config file glow-up helper 💖

okay bestie, so this is openssl-configutl from the OpenSSL fam — literally a configuration file helper command. she's here to untangle your messy configs and show you the receipts. 🎀

✨ SYNOPSIS ✨

openssl configutl [-help] [-config filename] [-out filename] [-noheader]

that's the whole vibe check right there. short, sweet, iconic. 👑

🌸 DESCRIPTION 🌸

okay so picture this: real-world OpenSSL configuration files that use the .include directive? they get messy. like, actually complex. and when you're staring at a pile of includes, you lowkey need to see what the final system-wide configuration actually ends up being. no cap. 😭

so that's what this tool is for, bestie — managing OpenSSL configuration files. right now it processes a configuration file with a possibly complex structure, and then dumps the effective resulting configuration file — by default straight to stdout. it's giving "let me just show you the truth of your config." 💅

🦋 OPTIONS 🦋

  • -help — prints a usage message. the classic "help me, I'm lost" button, and honestly? relatable. 🙈
  • -config filename — the configuration file you want her to deal with. if you skip it (bold move), the compiled-in one gets used, or the one you set via the OPENSSL_CONF environment variable. iykyk. 🌈
  • -out filename — the output file to write to instead of stdout. for when you want to keep the receipts in a file instead of just yelling them at your terminal. 🍓
  • -noheader — don't print the info about the original config file that's being processed. skipping the little intro, going straight to the content. main character energy fr fr. ⭐

🎀 EXAMPLES 🎀

dump the config file my.conf, processing all the .include directives, over to the file result.conf:

openssl configutl -config my.conf -out result.conf

slay. that's it. that's the move. 🔥
