# NAME

DSA_generate_key - generate DSA key pair

# SYNOPSIS

     #include <openssl/dsa.h>

     int DSA_generate_key(DSA *a);

# DESCRIPTION

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).

# SEE ALSO

DSA_new(3), ERR_get_error(3), RAND_bytes(3), DSA_generate_parameters_ex(3)
