5 DSA_new, DSA_free - allocate and free DSA objects
9 #include <openssl/dsa.h>
13 void DSA_free(DSA *dsa);
17 DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to
18 calling DSA_new_method(NULL).
20 DSA_free() frees the B<DSA> structure and its components. The values are
21 erased before the memory is returned to the system.
22 If B<dsa> is NULL nothing is done.
26 If the allocation fails, DSA_new() returns B<NULL> and sets an error
27 code that can be obtained by
28 L<ERR_get_error(3)>. Otherwise it returns a pointer
29 to the newly allocated structure.
31 DSA_free() returns no value.
35 L<dsa(3)>, L<ERR_get_error(3)>,
36 L<DSA_generate_parameters(3)>,
37 L<DSA_generate_key(3)>
41 DSA_new() and DSA_free() are available in all versions of SSLeay and OpenSSL.
