Pre-Shared Key

Type your pre-shared key in this field. A pre-shared key identifies a 

communicating party during a phase 1 IKE negotiation. It is called "pre-shared" 

because you have to share it with another party before you can communicate 

with them over a secure connection. 
Type from 8 to 31 case-sensitive ASCII characters or from 16 to 62 hexadecimal 

("0-9", "A-F") characters. You must precede a hexadecimal key with a "0x (zero 

x), which is not counted as part of the 16 to 62 character range for the key. For 

example, in "0x0123456789ABCDEF", 0x denotes that the key is hexadecimal 

and 0123456789ABCDEF is the key itself.
Both ends of the VPN tunnel must use the same pre-shared key. You will 

receive a PYLD_MALFORMED (payload malformed) packet if the same pre-

shared key is not used on both ends.
