DSA_do_sign(3) OpenSSL DSA_do_sign(3)NAME
DSA_do_sign, DSA_do_verify - raw DSA signature operations
SYNOPSIS
#include <openssl/dsa.h>
DSA_SIG *DSA_do_sign(const unsigned char *dgst, int dlen, DSA *dsa);
int DSA_do_verify(const unsigned char *dgst, int dgst_len,
DSA_SIG *sig, DSA *dsa);
DESCRIPTION
DSA_do_sign() computes a digital signature on the len byte message digest dgst using the private key dsa and returns it in a newly
allocated DSA_SIG structure.
DSA_sign_setup(3) may be used to precompute part of the signing operation in case signature generation is time-critical.
DSA_do_verify() verifies that the signature sig matches a given message digest dgst of size len. dsa is the signer's public key.
RETURN VALUES
DSA_do_sign() returns the signature, NULL on error. DSA_do_verify() returns 1 for a valid signature, 0 for an incorrect signature and -1
on error. The error codes can be obtained by ERR_get_error(3).
SEE ALSO dsa(3), ERR_get_error(3), rand(3), DSA_SIG_new(3), DSA_sign(3)HISTORY
DSA_do_sign() and DSA_do_verify() were added in OpenSSL 0.9.3.

Hello all,
My first post in this forum.
I am trying to download a file from a server to which I have been granted access. They setup a DSA public key and I have a local private key.
When i try to download the file it prompts me for my password.
How can I tell unix to use the DSA key... (1 Reply)
I have been asked to look into implementing digital signatures with emails sent from our Solaris servers to users. The emails would be sent from "application" accounts on the servers to users in the Windows world (exchange).
The only info I could find was a high level blurb (read by a CIO)... (1 Reply)
Hi all,
I have an problem with dual booting.
I installed windows7 and i want to install redhat linux on same system. When i insert the cd and boot with the cd it is not showing the hard drive. If i boot with hard disk its booting with windows7. But, if i boot with cdrom it is showing an... (7 Replies)
Yesterday customers of "OP5 monitor" (a commercial Nagios variant) were hit by a sudden GUI malfunction,
error "License signature is invalid: /etc/op5license/op5license.lic".
Two hours later the OP5 company provided a download of fix packages. (1 Reply)
I saw this and am wondering how I can add a signature so it shows on my posts.
Thanks.
