The fully renovated Anythink Perl Mack serves the North Denver community with a variety of spaces and programs for all ages. This sustainable facility includes a children’s pavilion, teen space, computer lab and program space. The landscaped site also includes a community garden, maintained by local community members in partnership with Denver Urban Gardens.
- Perl modules come with their own documentation. This includes modules installed from CPAN.On Unix-like (including Linux and Mac OS X) systems, you can access the documentation (for installed modules) with the perldoc command. For example, to get the documentation for IO::File, enter perldoc IO::File from your command prompt. Module documentation is also available on metacpan.org.
- MacPerl is an adaptation of Perl 5.0 for the Macintosh. Perl is an interpreted language optimized for scanning arbitrary text files, extracting information from those text files, and printing.
A good setup for Perl on macOS:
- Install 'Command Line Tools for Xcode', either directly or through Xcode, both available from Apple Developer downloads (free registration required). Xcode can also be installed through the App Store application.
- Open the Terminal.app (found in Applications -> Utilities) and copy & paste the command below into it (then press the 'return' key):
- Once this is finished (it takes several minutes), quit the Terminal app.
If you are interested in the details of the setup above...
- To build and install Perl and many of the thousands of useful Perl modules you need to have a compiler. For macOS the easiest way to get a compiler is to install 'Command Line Tools for Xcode' (about 100 Megs), either directly or through Xcode (several Gigs), both available from Apple Developer downloads. Xcode is also available through the App Store application. Some versions of the macOS install DVD or SSD come with the 'developer tools', which contains Xcode. Only the 'unix tools' section of Xcode is actually required, no specific version of Xcode is needed, the latest is available directly through the App Store.
- To interact with the command line and run Perl commands, a terminal application is needed. macOS comes with Terminal.app by default, there are alternatives available as well.
- macOS uses .bash_profile, but most other systems (and instructions) look for .bashrc, this code sets up .bash_profile to also run anything in .bashrc. There are other differences but these are not important to us.
- The Perlbrew website lists many of it's advantages. We recommend it here because it separates your installation from the system Perl, this makes upgrading your OS less likely to cause issues with your own Perl setup. It also means you can use a newer Perl than the default one which comes with your OS.
- App-cpanminus provides the
cpanm
tool, which makes installing modules very simple to do.

Net::SSH::Perl::Mac - MAC support for SSH2
Net::SSH::Perl::Mac (and its subclasses) provides MAC support for the SSH2 implementation in Net::SSH::Perl. In the SSH2 protocol, each packet sent between client and server (after the key exchange and algorithm negotiation phase) contains a MAC to protect its integrity. The sending party computes the MAC over the length, padding, and (encrypted) payload fields of the packet, then appends the MAC; and the receiving party recomputes the MAC against the data that it receives.
The MAC is computed using part of the key that is negotiated during the key exchange phase. During negotiation, packets do not contain MAC; after the SSH_MSG_NEWKEYS message is sent, each side turns on its respective encryption, MAC, and compression code, for each packet that is sent after that point.
Net::SSH::Perl supports two MAC algorithms: hmac-sha1 and hmac-md5. These algorithms are implemented, respectively, by Digest::HMAC_SHA1 and Digest::HMAC_MD5.
Each MAC object supports the following methods:
$mac = Net::SSH::Perl::Mac->new( $name )
Constructs a new MAC object and returns that object.
$mac->init( $key )
Initializes $mac and sets its key to $key (or rather, to a substring of key, key_len bytes long). As this implies, the key_len method should be called before init to set the intended length of the key.
Perl Mack Community Center
$mac->hmac( $data )
Computes the MAC over $data, using the key set in the initialization phase, and returns the MAC.
$mac->len
Returns the length of the MAC (eg.
20
for HMAC_SHA1).Php For Mac
$mac->key_len( $len )
Perl For Mac Osx
Given $len sets the key length of $mac to $len. This should be called before the init method, because init uses this value to take a substring of the provided key value.
Most of the time this should just be set to the MAC length (the len method); certain SSH implementations have a bug, however, wherein they always use only the first 16 bytes of the provided key.
$mac->enable
Enables the MAC object. This is used by Net::SSH::Perl::Kex to 'turn on' the MAC after key negotiation.
$mac->enabled
Tests the enabled flag (set with the enable method). This is used by Net::SSH::Perl::Packet to determine whether or not to compute a MAC on an outgoing packet.
