SYNOPSIS

 #include <openssl/ocsp.h>

 int OCSP_response_status(OCSP_RESPONSE *resp);
 OCSP_BASICRESP *OCSP_response_get1_basic(OCSP_RESPONSE *resp);

 int OCSP_RESPID_match(OCSP_RESPID *respid, X509 *cert);

 int OCSP_basic_sign(OCSP_BASICRESP *brsp, X509 *signer, EVP_PKEY *key,
                     const EVP_MD *dgst, STACK_OF(X509) *certs,
                     unsigned long flags);
 int OCSP_basic_sign_ctx(OCSP_BASICRESP *brsp, X509 *signer, EVP_MD_CTX *ctx,
                         STACK_OF(X509) *certs, unsigned long flags);

DESCRIPTION

OCSP_response_status() returns the OCSP response status of resp. It returns one of the values: OCSP_RESPONSE_STATUS_SUCCESSFUL, OCSP_RESPONSE_STATUS_MALFORMEDREQUEST, OCSP_RESPONSE_STATUS_INTERNALERROR, OCSP_RESPONSE_STATUS_TRYLATER OCSP_RESPONSE_STATUS_SIGREQUIRED, or OCSP_RESPONSE_STATUS_UNAUTHORIZED.

OCSP_response_get1_basic() decodes and returns the OCSP_BASICRESP structure contained in resp.

OCSP_response_create() creates and returns an OCSP_RESPONSE structure for status and optionally including basic response bs.

OCSP_RESPONSE_free() frees up OCSP response resp.

OCSP_RESPID_set_by_name() sets the name of the OCSP_RESPID to be the same as the subject name in the supplied X509 certificate cert for the OCSP responder.

OCSP_RESPID_set_by_key() sets the key of the OCSP_RESPID to be the same as the key in the supplied X509 certificate cert for the OCSP responder. The key is stored as a SHA1 hash.

Note that an OCSP_RESPID can only have one of the name, or the key set. Calling OCSP_RESPID_set_by_name() or OCSP_RESPID_set_by_key() will clear any existing setting.

OCSP_RESPID_match() tests whether the OCSP_RESPID given in respid matches with the X509 certificate cert.

OCSP_basic_sign() signs OCSP response brsp using certificate signer, private key key, digest dgst and additional certificates certs. If the flags option OCSP_NOCERTS is set then no certificates will be included in the request. If the flags option OCSP_RESPID_KEY is set then the responder is identified by key ID rather than by name. OCSP_basic_sign_ctx() also signs OCSP response brsp but uses the parameters contained in digest context ctx.

RETURN VALUES

OCSP_RESPONSE_status() returns a status value.

OCSP_response_get1_basic() returns an OCSP_BASICRESP structure pointer or NULL if an error occurred.

OCSP_response_create() returns an OCSP_RESPONSE structure pointer or NULL if an error occurred.

OCSP_RESPONSE_free() does not return a value.

OCSP_RESPID_set_by_name(), OCSP_RESPID_set_by_key(), OCSP_basic_sign(), and OCSP_basic_sign_ctx() return 1 on success or 0 on failure.

OCSP_RESPID_match() returns 1 if the OCSP_RESPID and the X509 certificate match or 0 otherwise.

NOTES

OCSP_response_get1_basic() is only called if the status of a response is OCSP_RESPONSE_STATUS_SUCCESSFUL.

HISTORY

The OCSP_RESPID_set_by_name(), OCSP_RESPID_set_by_key() and OCSP_RESPID_match() functions were added in OpenSSL 1.1.0a.

The OCSP_basic_sign_ctx() function was added in OpenSSL 1.1.1.
