OPENSSL-PRIME(1ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💅 OPENSSL-PRIME(1ossl) 💅

okay bestie, gather round because we're about to talk about prime numbers and honestly? it's giving main character energy ✨ this little icon of a command lives in OpenSSL and she's here to either check if your numbers are prime or generate some brand new ones for you. no cap. 🎀

✨ SYNOPSIS ✨

openssl prime [-help] [-hex] [-generate] [-bits num] [-safe] [-provider
name] [-provider-path path] [-provparam [name:]key=value] [-propquery
propq] [-checks num] [number ...]

🌸 DESCRIPTION 🌸

okay so the tea is: this command checks if the specified numbers are prime. that's literally her job. 🫶

and if you don't give her any numbers on the command line? then bestie you better be using the -generate flag, because that's the whole mood — she'll generate primes for you according to whatever requirements you specified with the rest of the flags. periodt. 👑

🦋 OPTIONS 🦋

  • -help — displays an option summary. the classic "help me help you" moment, iykyk 💁‍♀️
  • -hex — generates hex output. fancy formatting, we love to see it ✨
  • -generate — generates a prime number. this is the "make me something new" button and she ate 💅
  • -bits num — generates a prime with num bits. you're literally specifying the size, iconic behavior 🔥
  • -safe — when used with -generate, generates a "safe" prime. so if the number generated is n, then it checks that (n-1)/2 is also prime. double the prime, double the slay 💖
  • -provider name
  • -provider-path path
  • -provparam [name:]key=value
  • -propquery propq — see "Provider Options" in openssl(1), provider(7), and property(7). these are the deep-lore options, bestie, go read the other manuals for the full story 📚
  • -checks num — this parameter is ignored. literally she does not care about it. it's giving "i'm here but i'm not really here" 💀 not me including it anyway because completeness is the vibe 🙈
