| - cache info on various X.509v3 extensions and further derived certificate data |
| #include <openssl/x509v3.h> |
| int x509v3_cache_extensions(X509 *x, OSSL_LIB_CTX *libctx, const char *propq); |
| This function processes any X509v3 extensions present in an X509 object I<x> |
| and caches the result of that processing as well as further derived info, |
| for instance whether the certificate is self-issued or has version X.509v1. |
| It computes the SHA1 digest of the certificate using the default library context |
| and property query string and stores the result in x->sha1_hash, |
| or on failure sets B<EXFLAG_NO_FINGERPRINT> in x->flags. |
| It sets B<X509_SIG_INFO_VALID> in x->flags if x->siginf was filled successfully, |
| which may not be possible if a referenced algorithm is unknown or not available. |
| Many OpenSSL functions that use an X509 object call this function implicitly. |
| This function returns 0 if the extensions or other portions of the certificate |
| are invalid or an error occurred. |
