NAME

DSA_dup_DH − create a DH structure out of DSA structure

SYNOPSIS 

 #include <openssl/dsa.h>
 DH * DSA_dup_DH(const DSA *r);

DESCRIPTION

DSA_dup_DH() duplicates DSA parameters/keys as DH parameters/keys. q is lost during that conversion, but the resulting DH parameters contain its length.

RETURN VALUE

DSA_dup_DH() returns the new DH structure, and NULL on error. The error codes can be obtained by ERR_get_error(3).

NOTE

Be careful to avoid small subgroup attacks when using this.

SEE ALSO

dh(3), dsa(3), ERR_get_error(3)

DSA_dup_DH() was added in OpenSSL 0.9.4.
