NAME ^

Net::SSLGlue::FTP - extend Net::FTP for FTPS (SSL) and IPv6

SYNOPSIS ^

    use Net::SSLGlue::FTP;
    # SSL right from start
    my $ftps = Net::FTP->new( $host,
        SSL => 1,
        SSL_ca_path => ...
    );

    # SSL through upgrade of plain connection
    my $ftp = Net::FTP->new( $host );
    $ftp->starttls( SSL_ca_path => ... );

    # change protection mode to unencrypted|encrypted
    $ftp->prot('C'); # clear
    $ftp->prot('P'); # protected

DESCRIPTION ^

Net::SSLGlue::FTP extends Net::FTP so one can either start directly with SSL or switch later to SSL using starttls method (AUTH TLS command). If IO::Socket::IP or IO::Socket::INET6 are installed it will also transparently use IPv6.

By default it will take care to verify the certificate according to the rules for FTP implemented in IO::Socket::SSL.

METHODS ^

new

The method new of Net::FTP is now able to start directly with SSL when the argument <SSL = 1>> is given. One can give the usual SSL_* parameter of IO::Socket::SSL to Net::FTP::new.

starttls

If the connection is not yet SSLified it will issue the "AUTH TLS" command and change the object, so that SSL will now be used.

peer_certificate ...

Once the SSL connection is established you can use this method to get information about the certificate. See the IO::Socket::SSL documentation.

All of these methods can take the SSL_* parameter from IO::Socket::SSL to change the behavior of the SSL connection. The following parameters are especially useful:

SSL_ca_path, SSL_ca_file

Specifies the path or a file where the CAs used for checking the certificates are located. This is typically "etc/ssl/certs" on UNIX systems.

SSL_verify_mode

If set to 0, verification of the certificate will be disabled. By default it is set to 1 which means that the peer certificate is checked.

SSL_verifycn_name

Usually the name given as the hostname in the constructor is used to verify the identity of the certificate. If you want to check the certificate against another name you can specify it with this parameter.
