See \fIprovider\fR\|(7) for further information. .PP The \s-1DIGEST\s0 operation enables providers to implement digest algorithms and make them available to applications via the \s-1API\s0 functions \fIEVP_DigestInit_ex\fR\|(3), \&\fIEVP_DigestUpdate\fR\|(3) and \fIEVP_DigestFinal\fR\|(3) (and other related functions). .PP All \*(L"functions\*(R" mentioned here are passed as function pointers between \&\fIlibcrypto\fR and the provider in \fB\s-1OSSL_DISPATCH\s0\fR arrays via \&\fB\s-1OSSL_ALGORITHM\s0\fR arrays that are returned by the provider's \&\fIprovider_query_operation()\fR function (see \*(L"Provider Functions\*(R" in \fIprovider\-base\fR\|(7)). .PP All these \*(L"functions\*(R" have a corresponding function type definition named \fBOSSL_FUNC_{name}_fn\fR, and a helper function to retrieve the function pointer from an \fB\s-1OSSL_DISPATCH\s0\fR element named \&\fBOSSL_FUNC_{name}\fR. For example, the \*(L"function\*(R" \fIOSSL_FUNC_digest_newctx()\fR has these: .PP .Vb 3 \& typedef void *(OSSL_FUNC_digest_newctx_fn)(void *provctx); \& static ossl_inline OSSL_FUNC_digest_newctx_fn \& OSSL_FUNC_digest_newctx(const OSSL_DISPATCH *opf); .Ve .PP \&\fB\s-1OSSL_DISPATCH\s0\fR arrays are indexed by numbers that are provided as macros in \fIopenssl\-core_dispatch.h\fR\|(7), as follows: .PP .Vb 3 \& OSSL_FUNC_digest_newctx OSSL_FUNC_DIGEST_NEWCTX \& OSSL_FUNC_digest_freectx OSSL_FUNC_DIGEST_FREECTX \& OSSL_FUNC_digest_dupctx OSSL_FUNC_DIGEST_DUPCTX \& \& OSSL_FUNC_digest_init OSSL_FUNC_DIGEST_INIT \& OSSL_FUNC_digest_update OSSL_FUNC_DIGEST_UPDATE \& OSSL_FUNC_digest_final OSSL_FUNC_DIGEST_FINAL \& OSSL_FUNC_digest_digest OSSL_FUNC_DIGEST_DIGEST \& \& OSSL_FUNC_digest_get_params OSSL_FUNC_DIGEST_GET_PARAMS \& OSSL_FUNC_digest_get_ctx_params OSSL_FUNC_DIGEST_GET_CTX_PARAMS \& OSSL_FUNC_digest_set_ctx_params OSSL_FUNC_DIGEST_SET_CTX_PARAMS \& \& OSSL_FUNC_digest_gettable_params OSSL_FUNC_DIGEST_GETTABLE_PARAMS \& OSSL_FUNC_digest_gettable_ctx_params OSSL_FUNC_DIGEST_GETTABLE_CTX_PARAMS \& OSSL_FUNC_digest_settable_ctx_params OSSL_FUNC_DIGEST_SETTABLE_CTX_PARAMS .Ve .PP A digest algorithm implementation may not implement all of these functions. In order to be usable all or none of OSSL_FUNC_digest_newctx, OSSL_FUNC_digest_freectx, OSSL_FUNC_digest_init, OSSL_FUNC_digest_update and OSSL_FUNC_digest_final should be implemented. All other functions are optional. .SS "Context Management Functions" .IX Subsection "Context Management Functions" \&\fIOSSL_FUNC_digest_newctx()\fR should create and return a pointer to a provider side structure for holding context information during a digest operation. A pointer to this context will be passed back in a number of the other digest operation function calls. The parameter \fIprovctx\fR is the provider context generated during provider initialisation (see \fIprovider\fR\|(7)). .PP \&\fIOSSL_FUNC_digest_freectx()\fR is passed a pointer to the provider side digest context in the \fIdctx\fR parameter. This function should free any resources associated with that context. .PP \&\fIOSSL_FUNC_digest_dupctx()\fR should duplicate the provider side digest context in the \&\fIdctx\fR parameter and return the duplicate copy. .SS "Digest Generation Functions" .IX Subsection "Digest Generation Functions" \&\fIOSSL_FUNC_digest_init()\fR initialises a digest operation given a newly created provider side digest context in the \fIdctx\fR parameter. The \fIparams\fR, if not \s-1NULL,\s0 should be set on the context in a manner similar to using \fIOSSL_FUNC_digest_set_ctx_params()\fR. .PP \&\fIOSSL_FUNC_digest_update()\fR is called to supply data to be digested as part of a previously initialised digest operation. The \fIdctx\fR parameter contains a pointer to a previously initialised provider side context. \&\fIOSSL_FUNC_digest_update()\fR should digest \fIinl\fR bytes of data at the location pointed to by \fIin\fR. \&\fIOSSL_FUNC_digest_update()\fR may be called multiple times for a single digest operation. .PP \&\fIOSSL_FUNC_digest_final()\fR generates a digest started through previous \fIOSSL_FUNC_digest_init()\fR and \fIOSSL_FUNC_digest_update()\fR calls. The \fIdctx\fR parameter contains a pointer to the provider side context. The digest should be written to \fI*out\fR and the length of the digest to \&\fI*outl\fR. The digest should not exceed \fIoutsz\fR bytes. .PP \&\fIOSSL_FUNC_digest_digest()\fR is a \*(L"oneshot\*(R" digest function. No provider side digest context is used. Instead the provider context that was created during provider initialisation is passed in the \fIprovctx\fR parameter (see \fIprovider\fR\|(7)). \&\fIinl\fR bytes at \fIin\fR should be digested and the result should be stored at \&\fIout\fR. The length of the digest should be stored in \fI*outl\fR which should not exceed \fIoutsz\fR bytes. .SS "Digest Parameters" .IX Subsection "Digest Parameters" See \s-1\fIOSSL_PARAM\s0\fR\|(3) for further details on the parameters structure used by these functions. .PP \&\fIOSSL_FUNC_digest_get_params()\fR gets details of the algorithm implementation and stores them in \fIparams\fR. .PP \&\fIOSSL_FUNC_digest_set_ctx_params()\fR sets digest operation parameters for the provider side digest context \fIdctx\fR to \fIparams\fR. Any parameter settings are additional to any that were previously set. Passing \s-1NULL\s0 for \fIparams\fR should return true. .PP \&\fIOSSL_FUNC_digest_get_ctx_params()\fR gets digest operation details details from the given provider side digest context \fIdctx\fR and stores them in \fIparams\fR. Passing \s-1NULL\s0 for \fIparams\fR should return true. .PP \&\fIOSSL_FUNC_digest_gettable_params()\fR returns a constant \fB\s-1OSSL_PARAM\s0\fR array containing descriptors of the parameters that \fIOSSL_FUNC_digest_get_params()\fR can handle. .PP \&\fIOSSL_FUNC_digest_gettable_ctx_params()\fR and \&\fIOSSL_FUNC_digest_settable_ctx_params()\fR both return constant \&\fB\s-1OSSL_PARAM\s0\fR arrays as descriptors of the parameters that \&\fIOSSL_FUNC_digest_get_ctx_params()\fR and \fIOSSL_FUNC_digest_set_ctx_params()\fR can handle, respectively. The array is based on the current state of the provider side context if \fIdctx\fR is not \s-1NULL\s0 and on the provider side algorithm \fIprovctx\fR otherwise. .PP Parameters currently recognised by built-in digests with this function are as follows.

Any parameter settings are additional to any that were previously set. See \s-1\fIOSSL_PARAM\s0\fR\|(3) for further details on the parameters structure. .PP \&\fIOSSL_FUNC_digest_get_ctx_params()\fR gets details of currently set parameters values associated with the give provider side digest context \fIdctx\fR and stores them in \fIparams\fR.
