DESCRIPTION
OSSL_CMP_SRV_process_request() implements the generic aspects of a CMP server. Its
arguments are the OSSL_CMP_SRV_CTX srv_ctx and the CMP request message req. It does the
typical generic checks on req, calls the respective callback function (if present) for
more specific processing, and then assembles a result message, which may be a CMP error
message. If after return of the function the expression
OSSL_CMP_CTX_get_status(OSSL_CMP_SRV_CTX_get0_cmp_ctx(srv_ctx)) yields -1 then the
function has closed the current transaction, which may be due to normal successful end of
the transaction or due to an error.
OSSL_CMP_CTX_server_perform() is an interface to OSSL_CMP_SRV_process_request() that can
be used by a CMP client in the same way as OSSL_CMP_MSG_http_perform(3). The
OSSL_CMP_SRV_CTX must be set as transfer_cb_arg of client_ctx.
OSSL_CMP_SRV_CTX_new() creates and initializes an OSSL_CMP_SRV_CTX structure associated
with the library context libctx and property query string propq, both of which may be NULL
to select the defaults.
OSSL_CMP_SRV_CTX_free() deletes the given srv_ctx.
OSSL_CMP_SRV_CTX_init() sets in the given srv_ctx a custom server context pointer as well
as callback functions performing the specific processing of CMP certificate requests,
revocation requests, certificate confirmation requests, general messages, error messages,
and poll requests. All arguments except srv_ctx may be NULL. If a callback for some
message type is not given this means that the respective type of CMP message is not
supported by the server.
OSSL_CMP_SRV_CTX_get0_cmp_ctx() returns the OSSL_CMP_CTX from the srv_ctx.
OSSL_CMP_SRV_CTX_get0_custom_ctx() returns the custom server context from srv_ctx that has
been set using OSSL_CMP_SRV_CTX_init().
OSSL_CMP_SRV_CTX_set_send_unprotected_errors() enables sending error messages and other
forms of negative responses unprotected.
OSSL_CMP_SRV_CTX_set_accept_unprotected() enables acceptance of requests without
protection of with invalid protection.
OSSL_CMP_SRV_CTX_set_accept_raverified() enables acceptance of ir/cr/kur messages with
POPO 'RAVerified'.
OSSL_CMP_SRV_CTX_set_grant_implicit_confirm() enables granting implicit confirmation of
newly enrolled certificates if requested.
NOTES
CMP is defined in RFC 4210 (and CRMF in RFC 4211).
So far the CMP server implementation is limited to one request per CMP message (and
consequently to at most one response component per CMP message).
RETURN VALUES
OSSL_CMP_SRV_CTX_new() returns a OSSL_CMP_SRV_CTX structure on success, NULL on error.
OSSL_CMP_SRV_CTX_free() does not return a value.
OSSL_CMP_SRV_CTX_get0_cmp_ctx() returns a OSSL_CMP_CTX structure on success, NULL on
error.
OSSL_CMP_SRV_CTX_get0_custom_ctx() returns the custom server context that has been set
using OSSL_CMP_SRV_CTX_init().
All other functions return 1 on success, 0 on error.
HISTORY
The OpenSSL CMP support was added in OpenSSL 3.0.
