DSA_new 3 2003-07-24 0.9.9-dev OpenSSL

### NAME

DSA_new, DSA_free - allocate and free DSA objects

### LIBRARY

libcrypto, -lcrypto

### SYNOPSIS

     #include

     DSA* DSA_new(void);

     void DSA_free(DSA *dsa);

### DESCRIPTION

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.

### 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.

DSA_free() returns no value.

### SEE ALSO

openssl_dsa(3), ERR_get_error(3), DSA_generate_parameters(3), DSA_generate_key(3)

### HISTORY

DSA_new() and DSA_free() are available in all versions of SSLeay and OpenSSL.
