DES (Data Encryption Standard):
The Data Encryption Standard developed by IBM in 1977 is a 64-bit block
encryption block cipher using a 56-bit key.
Triple-DES (3DES):
The DES function performed three times with either two or three
cryptographic keys.
AES (Advanced Encryption Standard):
An encryption algorithm yet to be decided that will be used to replace the
aging DES encryption algorithm and that the NIST hopes will last for the
next 20 to 30 years.
NULL Algorithm:
It is a fast and convenient connecting mode to make sure its privacy and
authentication without encryption. NULL Algorithm doesn’t provide any other
safety services but a way to substitute ESP Encryption
SHA-1 (Secure Hash Algorithm-1):
A message-digest hash algorithm that takes a message less than 264 bits
and produces a 160-bit digest.
MD5:
MD5 is a common message digests algorithm that produces a 128-bit
message digest from an arbitrary length input, developed by Ron Rivest.
GRE/IPSec:
The device Select
GRE/IPSec (
Generic Routing Encapsulation)
packet seal
technology.
