okay so bestie, welcome to the 3ossl girlies club πŸ’– this is the manual page for X509_CRL_GET0_BY_SERIAL(3ossl) β€” aka your whole CRL revoked-entry toolkit. it's giving "I need to know who got kicked out and when" energy. let's go πŸ¦‹

int X509_CRL_get0_by_serial(X509_CRL *crl,
                            X509_REVOKED **ret, const ASN1_INTEGER *serial);
int X509_CRL_get0_by_cert(X509_CRL *crl, X509_REVOKED **ret, X509 *x);

STACK_OF(X509_REVOKED) *X509_CRL_get_REVOKED(X509_CRL *crl);

const ASN1_INTEGER *X509_REVOKED_get0_serialNumber(const X509_REVOKED *r);
const ASN1_TIME *X509_REVOKED_get0_revocationDate(const X509_REVOKED *r);

int X509_REVOKED_set_serialNumber(X509_REVOKED *r, ASN1_INTEGER *serial);
int X509_REVOKED_set_revocationDate(X509_REVOKED *r, ASN1_TIME *tm);

int X509_CRL_sort(X509_CRL *crl);

πŸŽ€ DESCRIPTION πŸŽ€

  • X509_CRL_get0_by_serial() β€” attempts to find a revoked entry in crl for the serial number serial. if it slays (successful), it sets *ret to the internal pointer of the matching entry. and because it's internal, *ret MUST NOT be freed after the call πŸ™ˆ like do not touch, do not free, hands off, periodt.
  • X509_CRL_get0_by_cert() β€” similar to X509_get0_by_serial() except it looks for a revoked entry using the serial number of certificate x. same vibe, different lookup key πŸ’«
  • X509_CRL_get_REVOKED() β€” returns an internal pointer to a STACK of all revoked entries for crl. it's giving the whole naughty list πŸ‘‘
  • X509_REVOKED_get0_serialNumber() β€” returns an internal pointer to the serial number of r.
  • X509_REVOKED_get0_revocationDate() β€” returns an internal pointer to the revocation date of r. when did they get the boot πŸ₯Ύ
  • X509_REVOKED_set_serialNumber() β€” sets the serial number of r to serial. heads up: the supplied serial pointer is not used internally, so you should free it after use. cleanup era 🧹
  • X509_REVOKED_set_revocationDate() β€” sets the revocation date of r to tm. same deal: the supplied tm pointer is not used internally, so free it after use.
  • X509_CRL_add0_revoked() β€” appends revoked entry rev to CRL crl. the pointer rev is used internally, so it MUST NOT be freed after the call β€” it gets freed when the parent CRL is freed. the CRL is its mom now, it lives there 🫢
  • X509_CRL_sort() β€” sorts the revoked entries of crl into ascending serial number order. tidy queen behavior ✨

πŸ¦‹ NOTES πŸ¦‹

applications can determine the number of revoked entries returned by X509_CRL_get_REVOKED() using sk_X509_REVOKED_num() and examine each one in turn using sk_X509_REVOKED_value(). lowkey a whole little iteration era, iykyk 🌈


⭐ RETURN VALUES ⭐

  • X509_CRL_get0_by_serial() and X509_CRL_get0_by_cert() return 0 for failure, 1 on success β€” except if the revoked entry has the reason "removeFromCRL" (8), in which case 2 is returned. yes bestie, 2 is a real return value here, not a typo, trust πŸ’€
  • X509_CRL_get_REVOKED() returns a STACK of revoked entries.
  • X509_REVOKED_get0_serialNumber() returns an ASN1_INTEGER structure.
  • X509_REVOKED_get0_revocationDate() returns an ASN1_TIME structure.
  • X509_REVOKED_set_serialNumber(), X509_REVOKED_set_revocationDate(), X509_CRL_add0_revoked() and X509_CRL_sort() return 1 for success and 0 for failure.
