💖 OSSL_CMP_HDR...TRANSACTIONID 💖

okay bestie, welcome to the 3SSL girlies' corner of the OpenSSL manual, aka the page literally titled OSSL_CMP_HDR...TRANSACTIONID. No cap, 3SSL is just our little section badge 🎀 and OpenSSL is, well, OpenSSL. Today's vibe: poking at CMP message headers. It's giving niche but iconic.

✨ NAME ✨

OSSL_CMP_HDR_get0_transactionID, OSSL_CMP_HDR_get0_recipNonce, OSSL_CMP_HDR_get0_geninfo_ITAVs — the lil functions that do stuff with CMP message headers 🫶

🌸 SYNOPSIS 🌸

#include <openssl/cmp.h>

ASN1_OCTET_STRING *OSSL_CMP_HDR_get0_transactionID(const
                                                   OSSL_CMP_PKIHEADER *hdr);
ASN1_OCTET_STRING *OSSL_CMP_HDR_get0_recipNonce(const
                                                OSSL_CMP_PKIHEADER *hdr);
STACK_OF(OSSL_CMP_ITAV)
    *OSSL_CMP_HDR_get0_geninfo_ITAVs(const OSSL_CMP_PKIHEADER *hdr);

🦋 DESCRIPTION 🦋

so basically, three lil getters. all of them take a PKIHeader and hand you back a pointer into it. that's the whole plot 💅

  • OSSL_CMP_HDR_get0_transactionID — gives you the transaction ID of the PKIHeader you passed in.
  • OSSL_CMP_HDR_get0_recipNonce — gives you the recipient nonce of the PKIHeader you passed in.
  • OSSL_CMP_HDR_get0_geninfo_ITAVs() — gives you the list of ITAVs sitting in the generalInfo field of the PKIHeader you passed in.

🧚 NOTES 🧚

CMP is defined in RFC 9810. that's the lore ✨

👑 RETURN VALUES 👑

every function here returns the intended pointer value, exactly like described up there ↑, or NULL if the respective entry does not exist and on error. that's it, that's the whole deal. NULL = no vibe, no entry, or something went wrong 😭

⭐ HISTORY ⭐

  • The OpenSSL CMP support was added in OpenSSL 3.0.
  • OSSL_CMP_HDR_get0_geninfo_ITAVs() was added in OpenSSL 3.3. (she's the new girl and she ate 💅)

and that's the page bestie, no notes 🤌 this was OpenSSL 4.0.3, dated 2026-09-29, and yes the manual name really is OSSL_CMP_HDR...TRANSACTIONID(3SSL) — the ellipsis is doing main character energy fr fr. mwah 💋✨
