34=head1 DESCRIPTION
35
36OCSP_response_status() returns the OCSP response status of I<resp>. It returns
37one of the values: I<OCSP_RESPONSE_STATUS_SUCCESSFUL>,
38I<OCSP_RESPONSE_STATUS_MALFORMEDREQUEST>,
39I<OCSP_RESPONSE_STATUS_INTERNALERROR>, I<OCSP_RESPONSE_STATUS_TRYLATER>
40I<OCSP_RESPONSE_STATUS_SIGREQUIRED>, or I<OCSP_RESPONSE_STATUS_UNAUTHORIZED>.
41
42OCSP_response_get1_basic() decodes and returns the I<OCSP_BASICRESP> structure
43contained in I<resp>.
44
45OCSP_response_create() creates and returns an I<OCSP_RESPONSE> structure for
46I<status> and optionally including basic response I<bs>.
47
48OCSP_RESPONSE_free() frees up OCSP response I<resp>.
49If the argument is NULL, nothing is done.
50
51OCSP_RESPID_set_by_name() sets the name of the OCSP_RESPID to be the same as the
52subject name in the supplied X509 certificate I<cert> for the OCSP responder.
53
54OCSP_RESPID_set_by_key_ex() sets the key of the OCSP_RESPID to be the same as the
55key in the supplied X509 certificate I<cert> for the OCSP responder. The key is
56stored as a SHA1 hash. To calculate the hash the SHA1 algorithm is fetched using
57the library ctx I<libctx> and the property query string I<propq> (see
58L<crypto(7)/ALGORITHM FETCHING> for further information).
59
60OCSP_RESPID_set_by_key() does the same as OCSP_RESPID_set_by_key_ex() except
61that the default library context is used with an empty property query string.
62
63Note that an OCSP_RESPID can only have one of the name, or the key set. Calling
64OCSP_RESPID_set_by_name() or OCSP_RESPID_set_by_key() will clear any existing
65setting.
66
67OCSP_RESPID_match_ex() tests whether the OCSP_RESPID given in I<respid> matches
68with the X509 certificate I<cert> based on the SHA1 hash. To calculate the hash
69the SHA1 algorithm is fetched using the library ctx I<libctx> and the property
70query string I<propq> (see L<crypto(7)/ALGORITHM FETCHING> for further
71information).
72
73OCSP_RESPID_match() does the same as OCSP_RESPID_match_ex() except that the
74default library context is used with an empty property query string.
75
76OCSP_basic_sign() signs OCSP response I<brsp> using certificate I<signer>, private key
77I<key>, digest I<dgst> and additional certificates I<certs>. If the I<flags> option
78I<OCSP_NOCERTS> is set then no certificates will be included in the response. If the
79I<flags> option I<OCSP_RESPID_KEY> is set then the responder is identified by key ID
80rather than by name. OCSP_basic_sign_ctx() also signs OCSP response I<brsp> but
81uses the parameters contained in digest context I<ctx>.
82
83=head1 RETURN VALUES
84
85OCSP_RESPONSE_status() returns a status value.
86
87OCSP_response_get1_basic() returns an I<OCSP_BASICRESP> structure pointer or
88I<NULL> if an error occurred.
89
90OCSP_response_create() returns an I<OCSP_RESPONSE> structure pointer or I<NULL>
91if an error occurred.
92
93OCSP_RESPONSE_free() does not return a value.
94
95OCSP_RESPID_set_by_name(), OCSP_RESPID_set_by_key(), OCSP_basic_sign(), and
96OCSP_basic_sign_ctx() return 1 on success or 0
97on failure.
98
99OCSP_RESPID_match() returns 1 if the OCSP_RESPID and the X509 certificate match
100or 0 otherwise.
101
102=head1 NOTES
103
104OCSP_response_get1_basic() is only called if the status of a response is
105I<OCSP_RESPONSE_STATUS_SUCCESSFUL>.
