DSA_dup_DH ? create a DH structure out of DSA structure |
#include <openssl/dsa.h> DH * DSA_dup_DH(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. |
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. |
dh(3), dsa(3), err(3) |
DSA_dup_DH() was added in OpenSSL 0.9.4. |
