@ -23,13 +23,12 @@ digest B<dgst> using the private key B<dsa> and places its ASN.1 DER
encoding at B<sigret>. The length of the signature is places in
*B<siglen>. B<sigret> must point to DSA_size(B<dsa>) bytes of memory.
DSA_sign_setup() may be used to precompute part of the signing
operation in case signature generation is time-critical. It expects
B<dsa> to contain DSA parameters. It places the precomputed values
in newly allocated B<BIGNUM>s at *B<kinvp> and *B<rp>, after freeing
the old ones unless *B<kinvp> and *B<rp> are NULL. These values may
be passed to DSA_sign() in B<dsa-E<gt>kinv> and B<dsa-E<gt>r>.
B<ctx> is a pre-allocated B<BN_CTX> or NULL.
DSA_sign_setup() is defined only for backward binary compatibility and
should not be used.
Since OpenSSL 1.1.0 the DSA type is opaque and the output of
DSA_sign_setup() cannot be used anyway: calling this function will only
cause overhead, and does not affect the actual signature
(pre-)computation.
DSA_verify() verifies that the signature B<sigbuf> of size B<siglen>
matches a given message digest B<dgst> of size B<len>.
