Applications should instead use \fBEVP_PKEY_new\fR\|(3) and \fBEVP_PKEY_free\fR\|(3). .PP \&\fBDSA_new()\fR allocates and initializes a \fBDSA\fR structure. It is equivalent to calling DSA_new_method(NULL). .PP \&\fBDSA_free()\fR frees the \fBDSA\fR structure and its components. The values are erased before the memory is returned to the system. If \fBdsa\fR is NULL nothing is done. .SH "RETURN VALUES" .IX Header "RETURN VALUES" If the allocation fails, \fBDSA_new()\fR returns \fBNULL\fR and sets an error code that can be obtained by \&\fBERR_get_error\fR\|(3). Otherwise it returns a pointer to the newly allocated structure. .PP \&\fBDSA_free()\fR returns no value. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBEVP_PKEY_new\fR\|(3), \fBEVP_PKEY_free\fR\|(3), \&\fBDSA_new\fR\|(3), \fBERR_get_error\fR\|(3), \&\fBDSA_generate_parameters\fR\|(3), \&\fBDSA_generate_key\fR\|(3) .SH HISTORY .IX Header "HISTORY" All of these functions were deprecated in OpenSSL 3.0. .SH COPYRIGHT .IX Header "COPYRIGHT" Copyright 2000\-2021 The OpenSSL Project Authors.
