=head1 NAME
|
|
|
|
DSA_new, DSA_free - allocate and free DSA objects
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/dsa.h>
|
|
|
|
The following functions have been deprecated since OpenSSL 3.0, and can be
|
|
hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
|
|
see L<openssl_user_macros(7)>:
|
|
|
|
DSA* DSA_new(void);
|
|
|
|
void DSA_free(DSA *dsa);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
All of the functions described on this page are deprecated.
|
|
Applications should instead use L<EVP_PKEY_new(3)> and L<EVP_PKEY_free(3)>.
|
|
|
|
DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to
|
|
calling DSA_new_method(NULL).
|
|
|
|
DSA_free() frees the B<DSA> structure and its components. The values are
|
|
erased before the memory is returned to the system.
|
|
If B<dsa> is NULL nothing is done.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
If the allocation fails, DSA_new() returns B<NULL> and sets an error
|
|
code that can be obtained by
|
|
L<ERR_get_error(3)>. Otherwise it returns a pointer
|
|
to the newly allocated structure.
|
|
|
|
DSA_free() returns no value.
