DSA_generate_key — generate DSA key pair


 #include <openssl/dsa.h>

 int DSA_generate_key(DSA *a);


DSA_generate_key() expects a to contain DSA parameters. It generates a new key pair and stores it in a->pub_key and a->priv_key.

The random generator must be seeded prior to calling DSA_generate_key(). If the automatic seeding or reseeding of the OpenSSL CSPRNG fails due to external circumstances (see RAND(7)), the operation will fail.

Return Values

DSA_generate_key() returns 1 on success, 0 otherwise. The error codes can be obtained by ERR_get_error(3).
