Cryptography
When using rot13 encoding algorithm you precisely only have to rotate each letter to the ordinal letter to code it, So the phrase It is very big for ne twainrk administrators to understand physical cryptography. will become Vg vf irel vzcbegnag south by east argjbex nqzvavfgengbef gb haqrefgnaq culfvpny pelcgbtencul. As each letter in the encoded essence is thirteen letters after the original , this is how the new content will show up.
When using Key concern at that place are two components that are required to encrypt data, these two things are an algorithm and a key. This key tends to be a large number that would be near impossible to guess. The surface alone of the number is so great that it would fair(a) be too difficult to scan for and would be a furious of time. In a symmetric cryptosystem there are two keys used for encryption and decryption, these two keys are trivially related, lots identical, cryptographic keys for both encryption of plaintext and decryption of ciphertext. In an asymmetrical system there is a key pair know as the encryption and decryption which are related scarce serve different means. The encryption key is known as the public key and the decryption key is known as the private key.
In the process of key management there is the option to encipher keys under higher level keys, however there is a time when these higher level keys pass on out and they must be established manually. These keys are break out into many different components and they are entrusted to many key management personnel. This method is so the key parts only harbour enough data to reveal the key only and just the key, DES keys tend to have an odd number of components, in which each individual has an odd parity. this odd parity is maintained when the components are combined and should be accompanied by a key check value to protect from keying errors.

Thanks for providing this useful guidance about cryptography. I am learning about it for the first time and found this article very helpful. Being a newbie I didn't find any difficulty in understanding all the points as you have explained in a very simple way.
