md5_final(9)

💖 NAME 💖

Okay so this is md5_final(9) from the Kernel API Manual, and its whole thing is: md5_final — Finish computing an MD5 message digest. Bestie, it's the glow-up finale for your MD5 digest. ✨

🌸 SYNOPSIS 🌸

void md5_final (struct md5_ctx *ctx , u8 out[static MD5_DIGEST_SIZE] );

That's the exact signature, no cap. 🫶

🎀 ARGUMENTS 🎀

• ctx — the context to finalize; must have been initialized. Like, do not come to this function with an uninitialized context, bestie. 💅
• out — (output) the resulting MD5 message digest. This is where the final digest lands. 💖

✨ DESCRIPTION ✨

After finishing, this zeroizes ctx. So the caller does not need to do it. The way it cleans up after itself is honestly iconic — you get the digest, and the context gets zeroized for you. 🧚

🌈 CONTEXT 🌈

Any context. Literally any. No restrictions, periodt. 👑
