• Unpacking a String:

  "\x00\x05hello\x00".unpack(:uint16_be, :string)
  # => [5, "hello"]

• Packing a Float:

  0.02.pack(:double)
  # => "{\x14\xAEG\xE1z\x94?"

• Packing an Array:

  [0x05, "hello"].pack(:uint16_be, :string)
  # => "\x00\x05hello\x00"

• Zlib inflate a String:

  "x\x9c+NM.J-\x01\0\b\xd1\x02\x87AAAAAAA".zlib_inflate
  # => "secret"

• Zlib deflate a String:

  "secret".zlib_deflate
  # => "x\x9c+NM.J-\x01\0\b\xd1\x02\x87"

• Return the SHA512 checksum of a String:

  "thunder growl".sha512
  # => "b2a1e560a497514dafda024f9e6fc2dfbfb178483251a708f07a88d4e157e5561604460da313ebc88dde2814ae58a15ae4085d00efb6a825a62f5be3215f5cbf"

  # => "1b11ba66f5e9d40a7eef699cd812e362"

• Packing an Integer:

  0x1337.pack(:uint32_le)
  # => "7\x13\0\0"

• Escaping a directory:

  Path.up(7)
  # => #<Ronin::Path:../../../../../../..>

• Base64 encode a String:

  "hello\0world".base64_encode
