pkcs7_parse_message(9)

💅 pkcs7_parse_message — bestie, we're parsing a PKCS#7 message ✨

Okay so real talk, this one lives in the Kernel API Manual and it's giving "crypto but make it cozy." It's pkcs7_parse_message(9) and I'm lowkey obsessed. 🎀

🌸 NAME 🌸

pkcs7_parse_message — parse a PKCS#7 message. That's it, that's the whole vibe. You hand it a blob, it makes sense of the blob. Iconic behaviour honestly. 💖

---

✨ SYNOPSIS ✨

struct pkcs7_message * pkcs7_parse_message (const void *data , size_t
datalen );

Like, you call it, it hands you back a struct pkcs7_message *. Main character return type fr fr. 🫶

---

🦋 ARGUMENTS 🦋

• data — the raw binary ASN.1 encoded message that's getting parsed. Raw. Binary. ASN.1. Say it with me, bestie — this is the actual bytes, no cap. 🙈
• datalen — the size of the encoded message. You gotta tell it how big the thing is, otherwise it's just guessing and we don't do guessing. 😭

ngl, both of these matter — data is what, datalen is how much of it, and yes you need both. 💀

🔥 SEE ALSO 🔥

• Kernel file ./crypto/asymmetric_keys/pkcs7_parser.c — the actual source, go read it, it's right there, iykyk 👑
• pkcs7_free_message(9) — the one you call after, because we clean up after ourselves in this house 🧚
• pkcs7_get_content_data(9) — the one that gets the good stuff out 🌈

and that's the whole page, periodt 💅

This lil transmission came from ./crypto/asymmetric_keys, dated October 2026, and the page itself is literally called pkcs7_parse_message(9) — so yeah, now you know the whole lore. mwah 🍓💜
