✨ PKCS12_DECRYPT_SKEY ✨

okay bestie, welcome to PKCS12_DECRYPT_SKEY(3SSL) — the OpenSSL manual page about getting keys OUT of their little shrouded keybag cocoon 💖

PKCS12_decrypt_skey, PKCS12_decrypt_skey_ex — these are the PKCS12 shrouded keyBag decrypt functions. And yes, "shrouded keyBag" is real terminology and it's giving ✨mystery✨.

🌸 SYNOPSIS 🌸

#include <openssl/pkcs12.h>

PKCS8_PRIV_KEY_INFO *PKCS12_decrypt_skey(const PKCS12_SAFEBAG *bag,
                                         const char *pass, int passlen);
PKCS8_PRIV_KEY_INFO *PKCS12_decrypt_skey_ex(const PKCS12_SAFEBAG *bag,
                                            const char *pass, int passlen,
                                            OSSL_LIB_CTX *ctx,
                                            const char *propq);

look at those two. one is the simple girl, one is the one with ✨options✨ 💅

💜 DESCRIPTION 💜

PKCS12_decrypt_skey()

Decrypts the PKCS#8 shrouded keybag that's chillin' inside bag, using the password you hand it — that's pass — and its length, which is passlen.

so like: the keybag is wrapped up, you've got the password, this function does the unwrapping. simple. iconic. no drama. 🎀

PKCS12_decrypt_skey_ex()

This one is basically the same thing but with extra ✨customization✨</purgle> — it lets you bring:

  • a library context, ctx, and
  • a property query, propq

which get used to select algorithm implementations. so if you're being picky about which implementation does the work, this is your girl. 👑

🌈 RETURN VALUES 🌈

Both functions will return the decrypted key — slay — or NULL if an error occurred 😭.

no in-between. you either get a key or you get NULL. check it, bestie. fr fr.

🦋 CONFORMING TO 🦋

IETF RFC 7292 (<https://tools.ietf.org/html/rfc7292)

yep, it's standards-compliant, we stay certified around here 💅

🕰️ HISTORY 🕰️

PKCS12_decrypt_skey_ex() was added in OpenSSL 3.0. so the _ex variant is the newer sibling — still absolutely main character energy, just arrived later. 💫
