.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBDSA_size()\fR returns the maximum size of an \s-1ASN.1\s0 encoded \s-1DSA\s0 signature
for key \fBdsa\fR in bytes. It can be used to determine how much memory must
be allocated for a \s-1DSA\s0 signature.
.PP
\&\fBdsa\->q\fR must not be \fB\s-1NULL\s0\fR.
.PP
\&\fBDSA_bits()\fR returns the number of bits in key \fBdsa\fR: this is the number
of bits in the \fBp\fR parameter.
.PP
\&\fBDSA_security_bits()\fR returns the number of security bits of the given \fBdsa\fR
key. See \fBBN_security_bits\fR\|(3).
