PGP interoperability
Looking over the PGP product offerings after their acquisition by Symantec, it seems they have dropped support for 2048- and 3072-bit DSA. This decision makes no sense to me, and is sufficiently weird that I wonder if the marketing copy is horribly in error. However, the marketing copy is clear -- across the whole of the PGP product line, DSA2 is no longer supported. Check the following URLs, click on System Requirements, and take a look at the Public Key Algorithms. For each product they offer: * Diffie-Hellman * DSA (1024-bit keys only) * RSA (up to 4096-bit keys) http://www.symantec.com/products/sysreq.jsp?pcid=pcat_business_contpvid=desktop_email_1 http://www.symantec.com/products/sysreq.jsp?pcid=pcat_info_risk_comppvid=desktop_corporate_1 http://www.symantec.com/products/sysreq.jsp?pcid=pcat_info_risk_comppvid=desktop_pro_1 ___ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
