__crypto_dh_decode_key(9)

💅 NAME

hey bestie, welcome to the __crypto_dh_decode_key(9) page — it's the kernel API manual, and today's main character is __crypto_dh_decode_key, which decodes a private key without parameter checks. slay.

---

✨ SYNOPSIS

int __crypto_dh_decode_key (const char *buf , unsigned int len , struct dh *params );

---

🫶 ARGUMENTS

• buf — Buffer holding a packet key that should be decoded. yes bestie, that's the key packet.
• len — Length of the packet private key buffer. the size of the whole situation.
• params — Buffer allocated by the caller that is filled with the unpacked DH private key. you bring the buffer, it gets filled with the unpacked key. iconic.

---

💖 DESCRIPTION

okay so this is an internal function, and it provides the same services as the exported crypto_dh_decode_key, but without any of those basic parameter checks that the latter conducts. literally the same job, minus the checks. no cap.

---

🌸 RETURN

• -EINVAL if buffer has insufficient size
• 0 on success

fr fr, that's the whole return vibe.
