OCSP_CRLID_NEW(3)          Library Functions Manual          OCSP_CRLID_NEW(3)

NAME
     OCSP_CRLID_new, OCSP_CRLID_free, OCSP_crlID_new - OCSP CRL extension

SYNOPSIS
     #include <openssl/ocsp.h>

     OCSP_CRLID *
     OCSP_CRLID_new(void);

     void
     OCSP_CRLID_free(OCSP_CRLID *crlid);

     X509_EXTENSION *
     OCSP_crlID_new(const char *url, long *number, char *time);

DESCRIPTION
     If a client asks about the validity of a certificate and it turns out to
     be invalid, the responder may optionally communicate which certificate
     revocation list the certificate was found on.  The required data is
     stored as an ASN.1 CrlID structure in the singleExtensions field of the
     SingleResponse structure.  The CrlID is represented by an OCSP_CRLID
     object, which will be stored inside the OCSP_SINGLERESP object documented
     in OCSP_SINGLERESP_new(3).

     OCSP_CRLID_new() allocates and initializes an empty OCSP_CRLID object.
     OCSP_CRLID_free() frees crlid.

     OCSP_crlID_new() accepts the url at which the CRL is available, the CRL
     number, and/or the time at which the CRL was created.  Each argument can
     be NULL, in which case the respective field is omitted.  The resulting
     CrlID structure is encoded in ASN.1 using X509V3_EXT_i2d(3) with
     criticality 0.

RETURN VALUES
     OCSP_CRLID_new() returns a new OCSP_CRLID object or NULL if an error
     occurred.

     OCSP_crlID_new() returns a new X509_EXTENSION object or NULL if an error
     occurred.
