🦋 DESCRIPTION 🦋

Okay so every OSSL_CRMF_MSG_get0_regCtrl_X() function hands back the matching control X from msg, but only if it’s actually present. 👀

• OSSL_CRMF_MSG_set1_regCtrl_regToken() — sets the regToken control in msg, copying the given tok as the value. See RFC 4211, section 6.1. 🎀
• OSSL_CRMF_MSG_set1_regCtrl_authenticator() — sets the authenticator control in msg, copying the given auth as the value. See RFC 4211, section 6.2. 🔐
• OSSL_CRMF_MSG_PKIPublicationInfo_push0_SinglePubInfo() — pushes the given spi to si. Consumes the spi pointer. 💅
• OSSL_CRMF_MSG_set0_SinglePubInfo() — sets in the given SinglePubInfo spi the method and publication location, in the form of a GeneralName, nm. The publication location is optional, and therefore nm may be NULL. The function consumes the nm pointer if present. Available methods are:

        # define OSSL_CRMF_PUB_METHOD_DONTCARE 0
        # define OSSL_CRMF_PUB_METHOD_X500     1
        # define OSSL_CRMF_PUB_METHOD_WEB      2
        # define OSSL_CRMF_PUB_METHOD_LDAP     3

• OSSL_CRMF_MSG_set_PKIPublicationInfo_action() — sets the action in the given pi using the given action as the value. See RFC 4211, section 6.3. Available actions are:

        # define OSSL_CRMF_PUB_ACTION_DONTPUBLISH   0
        # define OSSL_CRMF_PUB_ACTION_PLEASEPUBLISH 1

• OSSL_CRMF_MSG_set1_regCtrl_pkiPublicationInfo() — sets the pkiPublicationInfo control in the given msg, copying the given tok as the value. See RFC 4211, section 6.3. 🫶
• OSSL_CRMF_MSG_set1_regCtrl_protocolEncrKey() — sets the protocolEncrKey control in the given msg, copying the given pubkey as the value. See RFC 4211 section 6.6. 🔑
• OSSL_CRMF_MSG_set1_regCtrl_oldCertID() — sets the oldCertID regToken control in the given msg, copying the given cid as the value. See RFC 4211, section 6.5. 🧚
• OSSL_CRMF_CERTID_gen() — produces an OSSL_CRMF_CERTID_gen structure copying the given issuer name and serial number. 🌟

---

💖 RETURN VALUES 💖

• All OSSL_CRMF_MSG_get0_*() functions return the respective pointer value or NULL if not present and on error.
• All OSSL_CRMF_MSG_set1_*() functions return 1 on success, 0 on error.
• OSSL_CRMF_CERTID_gen() returns a pointer to the resulting structure or NULL on error.

---

🌈 NOTES 🌈

A function OSSL_CRMF_MSG_set1_regCtrl_pkiArchiveOptions() for setting an Archive Options Control is not yet implemented due to missing features to create the needed OSSL_CRMF_PKIARCHIVEOPTINS content. 😭 Not me waiting for that one to drop.
