NAME
DSA_new, DSA_free
— allocate and free DSA
objects
SYNOPSIS
#include
<openssl/dsa.h>
DSA*
DSA_new(void);
void
DSA_free(DSA *dsa);
DESCRIPTION
The DSA functions implement the Digital Signature Algorithm.
DSA_new()
allocates and initializes a DSA structure. It is
equivalent to calling
DSA_new_method(NULL).
DSA_free()
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.
RETURN VALUES
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.
