Encryption is a process involved in encoding information in a manner that only the individual or maybe the compute having the key will be able to decode it. Therefore, to encrypt a file simply means the ability to apply a mathematical function that changes every character in a given file into different other character forms. The encryption makes a file unreadable. By this, it means that no individual can real the file unless it becomes decrypted. Decryption of the file can only be done by the creator and the people authorized to do so. In this sense, there is something called encryption key pair that comprises of the decryption private key and the encryption public key. The part of the public key of the encryption key pair is usually used to encrypt data that can be decrypted through the corresponding decryption private key.
With all this, it is important to have key and certificate management. This typically involves the generation of keys for encryption as well as signing, the storage of the keys in specific certificates along with the administration of keys transparently and securely in a way that is given to the users to use in a particular place and time as may be required. There is also a key update in the management of the key and the certificate. Most importantly, keys must have a given lifetime and should be update often in a manner that is transparent, yet secure. Encryption is indeed the basis of the best forms of internet security and anyone serious with their online operations should embrace it.
