CRYPTDIR(1)

🎀 cryptdir: your directory’s crypt bestie 🎀

okay so real talk: this is the CRYPTDIR(1) page, and it’s about one little program doing a big job — encrypting or decrypting all files in a directory. It’s giving “tiny utility, main character energy” 💅✨

🏷️ NAME 🏷️

cryptdir — encrypt/decrypt all files in a directory 💖

---

✨ SYNOPSIS ✨

cryptdir [ dir ]
decryptdir [ dir ]

---

🌸 INTRODUCTION 🌸

So here’s the vibe: cryptdir encrypts all files in the current directory. If you hand it a directory as an argument — that’s the optional dir — it does the same thing there instead. 💫

And when you call it as decryptdir? Same program, different name, bestie. Literally the same binary wearing a little name tag, and this time it decrypts all the files. 🫶

💅 NOTES 💅

• When you’re encrypting, it prompts you for the password twice as a precautionary measure. That’s not it being extra for no reason — it would be a whole disaster to encrypt files with a password that wasn’t what you intended 😭🔐
• When you’re decrypting, it only prompts you once. If it’s the wrong password, no harm done. Chill behaviour, honestly. 🧊
• Encrypted files get the suffix .crypt appended. This prevents files from being encrypted twice. The suffix is removed upon decryption. 👑
• So like… you can easily add files to an encrypted directory and run cryptdir on it without worrying about the already encrypted files. Slay. No cap. ✨

💀 BUGS 💀

The man page is longer than the program. That’s it. That’s the bug. 💀😭
