	RFC 2410 (rfc2410) - The NULL Encryption Algorithm and Its Use With IPsec
		Algorithm Definition NULL is defined mathematically by the use of the Identity function I applied to a block of data b such that: NULL(b) = I(b) = b 2.1 Keying Material Like other modern ciphers, e.g., RC5 [RFC-2040], the NULL encryption algorithm can make use of keys of varying lengths.
		Performance The NULL encryption algorithm is significantly faster than other commonly used symmetric encryption algorithms and implementations of the base algorithm are available for all commonly used hardware and OS platforms.
		As stated in [ESP], while the use of encryption algorithms and authentication algorithms are optional in ESP, it is imperative that an ESP SA specifies the use of at least one cryptographically strong encryption algorithm or one cryptographically strong authentication algorithm or one of each.

		Block encryption algorithms take, as implicit arguments, the data to be encrypted or decrypted, the keying material, and their direction of operation.
		Simple stream encryption algorithms generate, based on the key, a stream of bytes which are XORed with the plain text data bytes to produce the cipher text on encryption and with the cipher text bytes to produce plain text on decryption.
		An undesirable characteristic of many encryption algorithms and/or their modes is that the same plaintext when encrypted with the same key has the same resulting ciphertext.

	Obfuscation of The Standard XOR Encryption Algorithm
		XOR Encryption is a popular encryption algorithm that is used in many browsers and it is blatantly simpleand fairly secure.

		When the algorithm is implemented in software or firmware, the processor on which the algorithm runs must be specified as part of the validation process.
		The algorithm is designed to encipher and decipher blocks of data consisting of 64 bits under control of a 64-bit key.** Deciphering must be accomplished by using the same key as for enciphering, but with the schedule of addressing the key bits altered so that the deciphering process is the reverse of the enciphering process.
		That is, the output of the algorithm has bit 40 of the preoutput block as its first bit, bit 8 as its second bit, and so on, until bit 25 of the preoutput block is the last bit of the output.

	Choosing encryption algorithm (Site not responding. Last check: )
		In case you are wondering why some encryption applications use 2048-bit or even larger keys, those applications use asymmetric (also called public key) encryption algorithms while Sentry is using symmetric encryption algorithms.
		Usually asymmetric algorithms are much slower but have additional properties useful in secure communication and digital signature applications.
		Due to the difference in mathematics, for a symmetric algorithm size of the key considered unbreakable is 128-bit, while for an asymmetric algorithm it is usually much higher.
