NAME

Crypt::SSLeay - OpenSSL & SSLeay glue that provides LWP https support

SYNOPSIS

lwp-request https://www.nodeworks.com

DESCRIPTION

This perl module provides support for the https protocol under LWP, so that a LWP::UserAgent can make https GET & HEAD requests.

The Crypt::SSLeay package contains Net::SSL, which is automatically loaded by LWP::Protocol::https on https requests, and provides the necessary SSL glue for that module to work via these deprecated modules:

Crypt::SSLeay::CTX
Crypt::SSLeay::Conn
Crypt::SSLeay::X509

Work on Crypt::SSLeay has been continued only to provide https support for the LWP - libwww perl libraries. If you want access to the OpenSSL API via perl, check out Sampo's Net::SSLeay.

INSTALL

OpenSSL

You must have OpenSSL or SSLeay installed before compiling this module. You can get the latest OpenSSL package from:

http://www.openssl.org

When installing openssl make sure your config looks like:

 > ./config --openssldir=/usr/local/openssl
or
 > ./config --openssldir=/usr/local/ssl

then
 > make
 > make test
 > make install

This way Crypt::SSLeay will pick up the includes and libraries automatically. If your includes end up going into a separate directory like /usr/local/include, then you will need to symlink /usr/local/openssl/include to /usr/local/include

Crypt::SSLeay

The latest Crypt::SSLeay can be found at your nearest CPAN, and also:

http://www.perl.com/CPAN-local/modules/by-module/Crypt/

Once you have downloaded it, Crypt::SSLeay installs easily using the make or nmake commands as shown below.

> perl Makefile.PL
> make
> make test
> make install

* use nmake for win32

BUILD NOTES

Solaris - Symbol Error: __umoddi3 : referenced symbol not found

Problem:

On Solaris x86, the default PERL configuration, and preferred, is to use the ld linker that comes with the OS, not gcc. Unfortunately during the OpenSSL build process, gcc generates in libcrypto.a, from bn_word.c, the undefined symbol __umoddi3, which is supposed to be later resolved by gcc from libgcc.a

The system ld linker does not know about libgcc.a by default, so when building Crypt::SSLeay, there is a linker error for __umoddi3

Solution:

The fix for this symlink your libgcc.a to some standard directory like /usr/local/lib, so that the system linker, ld, can find it when building Crypt::SSLeay.

FreeBSD 2.x.x / Solaris - ... des.h:96 #error _ is defined ...

If you encounter this error: "...des.h:96: #error _ is defined, but some strange definition the DES library cannot handle that...," then you need to edit the des.h file and comment out the "#error" line.

Its looks like this error might be common to other operating systems, and that occurs with OpenSSL 0.9.3. Upgrades to 0.9.4 seem to fix this problem.

NOTES

Many thanks to Gisle Aas for the original writing of this module and many others including libwww for perl. The web will never be the same :)
