DSA_NEW(3) Library Functions Manual DSA_NEW(3)

DSA_new, DSA_freeallocate and free DSA objects

#include <openssl/dsa.h>


DSA_free(DSA *dsa);

The DSA functions implement the Digital Signature Algorithm.

() allocates and initializes a DSA structure. It is equivalent to calling (NULL).

() frees the DSA structure and its components. The values are erased before the memory is returned to the system. If dsa is a NULL pointer, no action occurs.

If the allocation fails, DSA_new() returns NULL and sets an error code that can be obtained by ERR_get_error(3). Otherwise it returns a pointer to the newly allocated structure.
