X509_LOAD_CERT_FILE(3) FreeBSD Library Functions Manual NAME X509_load_cert_file, X509_load_crl_file, X509_load_cert_crl_file - read, decode, and cache certificates and CRLs SYNOPSIS #include <openssl/x509_vfy.h> int X509_load_cert_file(X509_LOOKUP *ctx, const char *file, int type); int X509_load_crl_file(X509_LOOKUP *ctx, const char *file, int type); int X509_load_cert_crl_file(X509_LOOKUP *ctx, const char *file, int type); DESCRIPTION X509_load_cert_file() with a type of X509_FILETYPE_PEM reads one or more certificates in PEM format from the given file using PEM_read_bio_X509_AUX(3); with a type of X509_FILETYPE_ASN1, if reads one certificate in DER format using d2i_X509_bio(3). The certificates read are added to the X509_STORE memory cache object associated with the given ctx using X509_STORE_add_cert(3). X509_load_crl_file() with a type of X509_FILETYPE_PEM reads one or more certificate revocation lists in PEM format from the given file using PEM_read_bio_X509_CRL(3); with a type of X509_FILETYPE_ASN1, if reads one certificate revocation lists in DER format using d2i_X509_CRL_bio(3). The certificate revocation lists read are added to the X509_STORE memory cache object associated with the given ctx using X509_STORE_add_crl(3). X509_load_cert_crl_file() with a type of X509_FILETYPE_PEM read one or more certificates and/or certificate revocation lists in PEM format from the given file using PEM_X509_INFO_read_bio(3) and adds them to the X509_STORE memory cache object associated with the given ctx using X509_STORE_add_cert(3) and X509_STORE_add_crl(3), respectively. X509_load_cert_crl_file() with a type of X509_FILETYPE_ASN1 is equivalent to X509_load_cert_file() and cannot be used to read a certificate revocation list. RETURN VALUES These functions return the number of objects loaded or 0 on error.
