NAME IO::Stream::MatrixSSL - Crypt::MatrixSSL plugin for IO::Stream VERSION This document describes IO::Stream::MatrixSSL version v2.0.2 SYNOPSIS use IO::Stream; use IO::Stream::MatrixSSL; # SSL server IO::Stream->new({ ... plugin => [ ... ssl => IO::Stream::MatrixSSL::Server->new({ crt => 'mysrv.crt', key => 'mysrv.key', }), ... ], }); # SSL client IO::Stream->new({ ... plugin => [ ... ssl => IO::Stream::MatrixSSL::Client->new({ cb => \&validate, }), ... ], }); sub validate { my ($ssl, $certs) = @_; my $stream = $ssl->stream(); # check cert, for ex.: $certs->[0]{subject}{commonName} return 0; } DESCRIPTION This module is plugin for IO::Stream which allow you to use SSL (on both client and server streams). INTERFACE IO::Stream::MatrixSSL::Client new $plugin_ssl_client = IO::Stream::MatrixSSL::Client->new(); $plugin_ssl_client = IO::Stream::MatrixSSL::Client->new({ crt => '/path/to/client.crt', key => '/path/to/client.key', pass => 's3cret', trusted_CA => '/path/to/ca-bundle.crt', cb => \&validate, }); Create and returns new IO::Stream plugin object. crt key pass Authenticate client on server using client's certificate. (You'll need Crypt::MatrixSSL3 compiled with support for client authentication.) crt and key should contain file names of client's certificate and private key (in PEM format), pass should contain password (as string) for private key. You can provide multiple file names with client's certificates in crt separated by ;. All optional (crt and key should be either both provided or both omitted, pass should be provided only if key file protected by password). trusted_CA This should be name of file (or files) with allowed CA certificates, required to check RSA signature of server certificate. Crypt::MatrixSSL3 provides such a file, so chances are you doesn't need to change default {trusted_CA} value ($Crypt::MatrixSSL3::CA_CERTIFICATES) if you just wanna connect to public https servers. There may be many files listed in {trusted_CA}, separated by ;. Each file can contain many CA certificates. cb This should be CODE ref to your callback, which will check server certificate. Callback will be called with two parameters: IO::Stream::MatrixSSL::Client (or IO::Stream::MatrixSSL::Server - if you're validating client's certificate) object and HASH ref with certificate details (see "SYNOPSIS" for example). Callback should return a number >=0 if this certificate is acceptable, and we can continue with SSL handshake, or number <0 if this certificate isn't acceptable and we should interrupt this connection and return error to IO::Stream user callback. If this function will throw exception, it will be handled just as return(-1). Hash with certificate details will looks this way: verified => $verified, notBefore => $notBefore, notAfter => $notAfter, subjectAltName => { dns => $dns, uri => $uri, email => $email, }, subject => { country => $country, state => $state, locality => $locality, organization => $organization, orgUnit => $orgUnit, commonName => $commonName, }, issuer => { country => $country, state => $state, locality => $locality, organization => $organization, orgUnit => $orgUnit, commonName => $commonName, }, where all values are just strings except these: $verified Status of cetrificate RSA signature check: -1 signature is wrong 1 signature is correct $notBefore $notAfter Time period when certificate is active, in format YYYYMMDDHHMMSSZ (for ex.: 20061231235959Z) stream $stream = $plugin_ssl_client->stream(); Returns IO::Stream object related to this plugin object. IO::Stream::MatrixSSL::Server Same as above for IO::Stream::MatrixSSL::Client. MIGRATION MatrixSSL often makes incompatible API changes, and so does Crypt::MatrixSSL3. Sometimes because of this IO::Stream::MatrixSSL also change API in incompatible way, and below explained how to migrate your code. 1.1.2 to 2.0.0 Parameters for validation callback was changed: sub validate { ### WAS my ($certs, $ssl, $stream) = ($_[0], @{ $_[1] }); ### NOW my ($ssl, $certs) = @_; my $stream = $ssl->stream(); ... } Some error messages was changed too.
