It provides a set of functions used by OpenSSL for the +implementation of the various \s-1DSA\s0 capabilities. See the dsa page for more +information. +.PP +\&\fBDSA_meth_new()\fR creates a new \fB\s-1DSA_METHOD\s0\fR structure. It should be given a +unique \fBname\fR and a set of \fBflags\fR. The \fBname\fR should be a \s-1NULL\s0 terminated +string, which will be duplicated and stored in the \fB\s-1DSA_METHOD\s0\fR object. It is +the callers responsibility to free the original string. The flags will be used +during the construction of a new \fB\s-1DSA\s0\fR object based on this \fB\s-1DSA_METHOD\s0\fR. Any +new \fB\s-1DSA\s0\fR object will have those flags set by default. +.PP +\&\fBDSA_meth_dup()\fR creates a duplicate copy of the \fB\s-1DSA_METHOD\s0\fR object passed as a +parameter. This might be useful for creating a new \fB\s-1DSA_METHOD\s0\fR based on an +existing one, but with some differences. +.PP +\&\fBDSA_meth_free()\fR destroys a \fB\s-1DSA_METHOD\s0\fR structure and frees up any memory +associated with it. +.PP +\&\fBDSA_meth_get0_name()\fR will return a pointer to the name of this \s-1DSA_METHOD.\s0 This +is a pointer to the internal name string and so should not be freed by the +caller. \fBDSA_meth_set1_name()\fR sets the name of the \s-1DSA_METHOD\s0 to \fBname\fR. The +string is duplicated and the copy is stored in the \s-1DSA_METHOD\s0 structure, so the +caller remains responsible for freeing the memory associated with the name. +.PP +\&\fBDSA_meth_get_flags()\fR returns the current value of the flags associated with this +\&\s-1DSA_METHOD.\s0 \fBDSA_meth_set_flags()\fR provides the ability to set these flags. +.PP +The functions \fBDSA_meth_get0_app_data()\fR and \fBDSA_meth_set0_app_data()\fR provide the +ability to associate implementation specific data with the \s-1DSA_METHOD.\s0 It is +the application's responsibility to free this data before the \s-1DSA_METHOD\s0 is +freed via a call to \fBDSA_meth_free()\fR. +.PP +\&\fBDSA_meth_get_sign()\fR and \fBDSA_meth_set_sign()\fR get and set the function used for +creating a \s-1DSA\s0 signature respectively.

This function will be +called in response to the application calling \fBDSA_new()\fR (if the current default +\&\s-1DSA_METHOD\s0 is this one) or \fBDSA_new_method()\fR. The \fBDSA_new()\fR and \fBDSA_new_method()\fR +functions will allocate the memory for the new \s-1DSA\s0 object, and a pointer to this +newly allocated structure will be passed as a parameter to the function. This +function may be \s-1NULL.\s0 +.PP +\&\fBDSA_meth_get_finish()\fR and \fBDSA_meth_set_finish()\fR get and set the function used +for destroying an instance of a \s-1DSA\s0 object respectively.
