SSL SUPPORT

4

The libwww-perl package has support for using SSL/TLSv1 with its HTTP





5

client and server classes. This support makes it possible to access





6

https schemed URLs with LWP. Because of the problematic status of





7

encryption software in general and certain encryption algorithms in





8

particular, in several countries, libwww-perl package doesn't include





9

SSL functionality out-of-the-box.





10






11

Encryption support is obtained through the use of Crypt::SSLeay or





12

IO::Socket::SSL, which can both be found from CPAN. While libwww-perl





13

has "plug-and-play" support for both of these modules (as of v5.45),





14

the recommended module to use is Crypt::SSLeay. In addition to





15

bringing SSL support to the LWP package, IO::Socket::SSL can be used





16

as an object oriented interface to SSL encrypted network sockets.





17






18

There is yet another SSL interface for perl called Net::SSLeay. It has





19

a more complete SSL interface and can be used for web client





20

programming among other things but doesn't directly support LWP.





21






22

The underlying SSL support in all of these modules is based on OpenSSL





23

<http://www.openssl.org/> (formerly SSLeay). For WWW-server side SSL





24

support (e.g. CGI/FCGI scripts) in Apache see <http://www.modssl.org/>.
