3 | =head1 NAME | ||
4 | |||
5 | DSA_do_sign, DSA_do_verify - raw DSA signature operations | ||
6 | |||
7 | =head1 SYNOPSIS | ||
8 | |||
9 | #include <openssl/dsa.h> | ||
10 | |||
11 | DSA_SIG *DSA_do_sign(const unsigned char *dgst, int dlen, DSA *dsa); | ||
12 | |||
13 | int DSA_do_verify(const unsigned char *dgst, int dgst_len, | ||
14 | DSA_SIG *sig, DSA *dsa); | ||
15 | |||
16 | =head1 DESCRIPTION | ||
17 | |||
18 | DSA_do_sign() computes a digital signature on the B<len> byte message | ||
19 | digest B<dgst> using the private key B<dsa> and returns it in a | ||
20 | newly allocated B<DSA_SIG> structure. | ||
21 | |||
22 | L<DSA_sign_setup(3)|DSA_sign_setup(3)> may be used to precompute part | ||
23 | of the signing operation in case signature generation is | ||
24 | time-critical. | ||
25 | |||
26 | DSA_do_verify() verifies that the signature B<sig> matches a given | ||
27 | message digest B<dgst> of size B<len>. B<dsa> is the signer's public | ||
28 | key. | ||
29 | |||
30 | =head1 RETURN VALUES | ||
31 | |||
32 | DSA_do_sign() returns the signature, NULL on error. DSA_do_verify() | ||
33 | returns 1 for a valid signature, 0 for an incorrect signature and -1 | ||
34 | on error. The error codes can be obtained by | ||
35 | L<ERR_get_error(3)|ERR_get_error(3)>. | ||

44 | |||
45 | DSA_do_sign() and DSA_do_verify() were added in OpenSSL 0.9.3. | ||
