DSA_dup_DH(3openssl) OpenSSL DSA_dup_DH(3openssl) 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.
