Backward compatibility for HASP dongles broken starting FNP-11.16.0

Yes

Symptoms:

Starting FNP-11.16.0, (shared HASP dongle driver and dll's are for version 7.61) the dongle dll's will not be backward compatible for FNP-11.13.1 and older version of clients.

Diagnosis:

FNP Toolkit Version	HASP dongle driver (Signed by Thales)	HASP Dll's (Signed by Flexera)	Comments: ====================================================================
v 11.13.1	Version: 6.56 Digest Algorithm: SHA1 VeriSign Class 3 Code Signing 2010 CA	Version: 7.1 Digest Algorithm: SHA1 VeriSign Class 3 Code Signing 2010 CA
v 11.14.0	Version: 7.41 Digest Algorithm: SHA1 VeriSign Class 3 Code Signing 2010 CA	Version : 7.4 Digest Algorithm: SHA 256 VeriSign Class 3 Code Signing 2010 CA	FNP-14155 FNP-14401 FNP-11607 Microsoft will soon require SHA-2 (SHA256) signing: http://social.technet.microsoft.com/wiki/contents/articles/32288.windows-enforcement-of-authenticode-code-signing-and-timestamping.aspx FNP kept signing 'dll's' with VeriSign to maintain the backward compatibility. In addition to that code wise a check was added (to source code) which allows 'VeriSign' as well as 'Symantec' Issuers during authentication - so that when in future we move from VeriSign to Symantec - backward compatibility is maintained.
v 11.15.1	Version : 7.60 Digest Algorithm: SHA1 DigiCert EV Code Signing CA (SHA2)	Version : 7.6 Digest Algorithm: SHA 256 VeriSign Class 3 Code Signing 2010 CA
v11.16.0	Version : 7.80 Digest Algorithm: SHA1 DigiCert EV Code Signing CA (SHA2)	Version : 7.61 Digest Algorithm: SHA 256 Symantec Class 3 SHA256 Code Signing CA	Switched from "VeriSign" to "Symantec" As enhancement done in FNP-11.14.0 was not in FNP-11.13.1 and earlier, hence once we moved to "Symantec" for signing dll's, those client will fail to detect the dongle - if using v11.16.0 version shared dll's.

Workaround:

For Flex-enabled clients build with FNP toolkit v11.13.1 and older, to have them working seamlessly in a mixed client version environment (v11.14, v1.15 and later), use the latest version (or as provided with latest GA FNP toolkit) dongle driver, but at most the HASP dll's from FNP-11.15.1 toolkit.
