+
+ <para>
+ The size of the compiled-in DH parameters has been increased from
+ 1024 to 2048 bits, making DH key exchange more resistant to
+ brute-force attacks. However, some old SSL implementations, notably
+ some revisions of Java Runtime Environment version 6, will not accept
+ DH parameters longer than 1024 bits, and hence will not be able to
+ connect over SSL. If it's necessary to support such old clients, you
+ can use custom 1024-bit DH parameters instead of the compiled-in
+ defaults. See <xref linkend="guc-ssl-dh-params-file">.
