sha1_final(9)

🎀 NAME 🎀

okay bestie, meet sha1_final(9) from the Kernel API Manual — the function that does one thing and does it iconically: Finish computing a SHA-1 message digest. that’s the whole name-and-purpose vibe, no cap ✨

✨ SYNOPSIS ✨

void sha1_final (struct sha1_ctx *ctx , u8 out[static SHA1_DIGEST_SIZE]
);

🌸 ARGUMENTS 🌸

• ctx — the context to finalize; it must have been initialized 💅
• out — (output) the resulting SHA-1 message digest 🫶

💖 DESCRIPTION 💖

so after it finishes, this zeroizes ctx. literally wipes it for you. so the caller does not need to do it — periodt, that’s the whole tea 🍓

🦋 CONTEXT 🦋

Any context. that’s the vibe check, bestie — no special context restrictions listed here 🌈
