DSA_dup_DH — create a DH structure out of DSA structure


 #include <openssl/dsa.h>

 DH *DSA_dup_DH(const DSA *r);


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 Values

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


Be careful to avoid small subgroup attacks when using this.
