README - Net::SSLeay Perl module for using OpenSSL $Id: README 461 2016-04-04 03:32:38Z mikem-guest $ By popular demand... -------------------- perl -MNet::SSLeay -e '($p)=Net::SSLeay::get_https("www.openssl.org", 443, "/"); print $p' Prerequisites ------------- perl-5.6.1 though anything starting from perl5.003 probably works. OpenSSL-0.9.6j through to at least OpenSSL-1.0.2 and probably later http://www.openssl.org/ - On Linux, you can either build and install OpenSSL from scratch (its very portable) or you can install the appropriate OpenSSL 'devel' package for your Linux distribution: (rpm openssl-devel, deb libssl-dev). Note: SSLeay is no longer supported. If you want to use Net::SSLeay with SSLeay or early versions of OpenSSL, use version 1.03. The support for SSLeay was dropped due to nobody maintaining it (all active work goes on with OpenSSL) and due to incompatible API changes in OpenSSL-0.9.2b. OpenSSL-0.9.1c support has also been dropped, version 1.03 was the last one to support that. You should use the same C compiler and options to compile OpenSSL, perl, and Net::SSLeay. This is the only supported configuration. If you insist on using different compilers (perhaps because you obtained either OpenSSL or perl as binaries from a vendor and they used a compiler that you do not have) then all requests for support will be ignored. If the only way for you to use the same compiler for all three components is to recompile your openssl or perl, then that is exactly what I expect you to do before asking for support. Installing ---------- Unix: # build or install OpenSSL as per instructions in that package gunzip bt # show stack trace gdb perl # run live with debugging # set break point in SSLeay.xs or in suspect function of OpenSSL > br XS_Net__SSLeay_connect > run yourscript.pl arg arg For gdb'ing make sure gdb finds all the relevant source code. This may mean that you must run perl and OpenSSL from the directories where the respective makefiles build them. You can also enable PR and PRN macros in SSLeay.xs and sprinkle even some more around the code to figure out what's happening. Some exotic configurations of perl may cause unstability: make sure OpenSSL uses the same malloc as perl. Recompile perl without threads. Try not using the PerlIO abstraction. If you need to tweak build for some platform, please let me know so I can fix it. Patches and gdb session dumps are also welcome.

From version 1.66 onwards, this Net-SSLeay package is issued under the "Perl Artistic License 2.0", the same license as Perl itself.

And remember, you, and nobody else but you, are responsible for auditing this module and OpenSSL library for security problems, backdoors, and general suitability for your application. Recommended reading ------------------- ===> HTTP protocol specification. It applies 100% to HTTPS too and doing password authentication is explained there. <=== If you are newbie interested in grabbing web pages from https servers, please read HTTP documentation from http://www.w3c.org/ before asking trivial questions. That document also covers the basic-auth FAQ (URLs like http://user:pass@host). Do not ask questions about authentication before consulting the HTTP specification. HTTPS is just HTTP in SSL transport. If you are doing advanced stuff, and don't find documentation you need, please try to extrapolate from OpenSSL documentation (which unfortunately is quite sparse) and the source code. If you run into build problems, especially regarding shared libraries, check your perl documentation, especially the perlxtut(1) man page, which gives excellent tutorial of the build process of XSUBs. perlxtut(1) perlxs(1) perlguts(1) perlcall(1) Say `perldoc Net::SSLeay' _NOW_!
