rsa_parse_pub_key(9)

✨ rsa_parse_pub_key(9) ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — this one's a lil' RSA helper and it's genuinely iconic. it decodes a BER encoded buffer and stashes it in the struct rsa_key you hand it — and here's the cute part: it gives you back pointers to the raw key as is, so you (the caller) can copy it, or MPI parse it, or whatever else you wanna do with it. slay 💅

🌸 SYNOPSIS 🌸

int rsa_parse_pub_key (struct rsa_key *rsa_key , const void *key ,
unsigned int key_len );

💖 ARGUMENTS 💖

• rsa_key — your struct rsa_key key representation, the spot where the good stuff gets stored 🫶
• key — the key itself, all wrapped up in BER format ✨
• key_len — literally just the length of key, no cap 📏

⭐ RETURN ⭐

0 on success, or an error code if something went sideways 😭 — vibe check that return value fr fr.

🦋 SEE ALSO 🦋

• Kernel file ./crypto/rsa_helper.c
• rsa_parse_priv_key(9) 👑

ngl bestie, remember the pointers are to the raw key as is — nothing got copied for you, so handle it accordingly 💀

mwah, that's a wrap from the ./crypto corner of the kernel 💜 October 2026 🧚 🍓 🌈
