In Live server we have perl version 5.6.1,recently we have enabled TLS 1.2 which resulted in a error "500 SSL Negotiation failed". Earlier we have TLS 1.0 we don't have any issues. Enabling TLS 1.2 is unavoidable which is mandatory. How to resolve this issue?
I have searched & found that SOAP-LITE module has to be installed in order to resolve the above issue but the version 5.6.1 does not support SOAP-LITE module. It is available in active perl 5.8 and above version. Is it adviseable to upgrade to 5.8 version inorder to install soap::Lite?
I have used the modules MSSQL::DBLIB and MSSQL::SQLLIB in this project, Will upgrade supports this module?
回答1:
Given how old your version of Perl is it is very likely that your version of OpenSSL (which is used at the end for SSL connectivity in Perl) is as old too. Support for TLS 1.2 was added with OpenSSL 1.0.1 which was released 2012. Perl 5.6.1 was released in 2000 while in 2012 we already had Perl 5.14.
And it is not unlikely that the rest of your software is similar outdated and unsupported and likely insecure too.
How to resolve this issue?
Finally upgrade your long unsupported software stack. You can try to only update openssl and rebuild Crypt::SSLeay (likely no Net::SSLeay is used yet) to keep changes minimal but I'm not sure that this will work or even compile.
