5 DSA_dup_DH - create a DH structure out of DSA structure
9 #include <openssl/dsa.h>
11 DH *DSA_dup_DH(const DSA *r);
15 DSA_dup_DH() duplicates DSA parameters/keys as DH parameters/keys. q
16 is lost during that conversion, but the resulting DH parameters
21 DSA_dup_DH() returns the new B<DH> structure, and NULL on error. The
22 error codes can be obtained by L<ERR_get_error(3)>.
26 Be careful to avoid small subgroup attacks when using this.
