VPN stands for virtual private network. The virtual means that this privacy is accomplished allthough it is by nature not private at all when you communicate over a public network - the internet. The data flows through all kinds of networks. All of them being owned and operated by someone else than you or your company, so from a privacy point of view: Those networks can not be trusted. So the virtual privacy is being achieved by strong encryption. This creates the methaphor that is a private network because only allowed people are connected or configured to enter the encrypted space.

There are lots of software packages and some different protocols that are used to operate VPNs.

The count of software packages are plenty. The protocols are relatively few, like:
  • IPSec
  • OpenVPN
  • wiregard
  • Closed source vendor specific implementations, created completely on their own or based on one of the above

The different properties of a vpn solution are:
  • Manageability(Tools to manage Access and Accounts and Distribution)
  • Compatibility with protocols(as shown above)
  • Closed Source/Open Source
  • Commercial products usally introduce their own hardware product series to be used with the VPN software

NAME
String::Parity, setEvenParity, setOddParity, setSpaceParity, setMarkParity, isEvenParity, isOddParity isSpaceParity, isMarkParity, Even- Bytes, OddBytes, SpaceBytes, MarkBytes, showParity, showMarkSpace - Parity (odd/even/mark/space) handling functions SYNOPSIS
use String::Parity; use String::Parity qw(:DEFAULT /show/); DESCRIPTION
setEvenParity LIST Copies the elements of LIST to a new list and converts the new elements to strings of bytes with even parity. In array context returns the new list. In scalar context joins the elements of the new list into a single string and returns the string. setOddParity LIST Like setEvenParity function, but converts to strings with odd parity. setSpaceParity LIST Like setEvenParity function, but converts to strings with space (High bit cleared) parity. setMarkParity LIST Like setEvenParity function, but converts to strings with mark (High bit set) parity. EvenBytes LIST Returns the number of even parity bytes in the elements of LIST. OddBytes LIST Returns the number of odd parity bytes in the elements of LIST. SpaceBytes LIST Returns the number of space parity bytes in the elements of LIST. MarkBytes LIST Returns the number of mark parity bytes in the elements of LIST. isEvenParity LIST Returns TRUE if the LIST contains no byte with odd parity, FALSE otherwise. isOddParity LIST Returns TRUE if the LIST contains no byte with even parity, FALSE otherwise. isSpaceParity LIST Returns TRUE if the LIST contains no byte with mark parity, FALSE otherwise. isMarkParity LIST Returns TRUE if the LIST contains no byte with space parity, FALSE otherwise. showParity LIST Like setEvenParity function, but converts bytes with even parity to 'e' and other bytes to 'o'. The function showParity must be imported by a specialised import list. showMarkSpace LIST Like setEvenParity function, but converts bytes with space parity to 's' and other bytes to 'm'. The function showMarkSpace must be imported by a specialised import list. NOTES
Don't use this module unless you have to communicate with some old device or protocol. Please make your application 8 bit clean and use the internationally standardised ISO-8859-1 character set. AUTHOR
