DSA_do_sign(3)							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
       The DSA_do_sign() function 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.

       The  DSA_sign_setup()  function	can  be used to precompute part of the
       signing operation in case signature generation is time-critical.

       The DSA_do_verify() function verifies that the signature sig matches  a
       given  message digest dgst of size len.	The dsa is the signer's public
       key.

RETURN VALUES
       The DSA_do_sign() function returns the signature, NULL on  error.   The
       DSA_do_verify()	function  returns  1  for  a valid signature, 0 for an
       incorrect signature and -1 on error. The error codes  can  be  obtained
       from ERR_get_error().

HISTORY
       The  DSA_do_sign()  and DSA_do_verify() functions were added in OpenSSL
       0.9.3.
