=head1 NAME

VM::EC2::KeyPair - Object describing an Amazon EC2 ssh key pair

=head1 SYNOPSIS

  use VM::EC2;

  $ec2     = VM::EC2->new(...);
  @pairs   = $ec2->describe_key_pairs();

  foreach (@pairs) {
      $fingerprint = $_->keyFingerprint;
      $name        = $_->keyName;
  }

  $newkey = $ec2->create_key_pair("fred's key");
  print $newkey->privateKey;

=head1 DESCRIPTION

This object represents an Amazon EC2 ssh key pair, and is returned
by VM::EC2->describe_key_pairs().

=head1 METHODS

These object methods are supported:

 keyName         -- Name of the key, e.g. "fred-default"
 name            -- Shorter version of keyName()

 keyFingerprint  -- Key's fingerprint
 fingerprint     -- Shorter version of keyFingerprint()

 keyMaterial     -- PEM encoded RSA private key (only available when
                    creating a new key)
 privateKey      -- More intuitive version of keyMaterial()

=head1 STRING OVERLOADING

When used in a string context, this object will interpolate the
keyName.
