.PP
The following functions have been deprecated since OpenSSL 3.0, and can be
hidden entirely by defining \fB\s-1OPENSSL_API_COMPAT\s0\fR with a suitable version value,
see \fBopenssl_user_macros\fR\|(7):
.PP
.Vb 1
\& int DSA_generate_key(DSA *a);
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
All of the functions described on this page are deprecated.
Applications should instead use \fBEVP_PKEY_keygen_init\fR\|(3) and
\&\fBEVP_PKEY_keygen\fR\|(3) as described in \s-1\fBEVP_PKEY\-DSA\s0\fR\|(7).
.PP
\&\fBDSA_generate_key()\fR expects \fBa\fR to contain \s-1DSA\s0 parameters. It generates
a new key pair and stores it in \fBa\->pub_key\fR and \fBa\->priv_key\fR.
.PP
The random generator must be seeded prior to calling \fBDSA_generate_key()\fR.
If the automatic seeding or reseeding of the OpenSSL \s-1CSPRNG\s0 fails due to
external circumstances (see \s-1\fBRAND\s0\fR\|(7)), the operation will fail.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBDSA_generate_key()\fR returns 1 on success, 0 otherwise.
The error codes can be obtained by \fBERR_get_error\fR\|(3).
