Encryption is a method by which information is taken and changed into something which cannot be understood by someone until they know how to change it back into something logical. The process of changing the information into gibberish is known encryption and the process of translating it back is known as decryption. In similar manner the encrypted message are handled and taken care of.
There are different types of encrypted messages types which are differentiated on the bases of the level of difficulty in encryptions. Some of the know terms are military grade encryption, bank level encryptions. Military encrypted message are hard to break codes and that is why they increase the safety of your documents.
In lay man term military encrypted message means that the encryption is one of the hardest ones and toughest to break so that gives your data more safety and security. Due to higher level of encryptions the data is less prone to be hacked and gives more security to the documents.
The interesting part is that military grade encryption is just a term for users to make them feel that it is more secure and safe form of encrypted message where as in technical term it is Advanced Encryption Standard (AES) 256 encryption. AES-256 uses more processing power to encrypt and decrypt information making it more difficult for hackers to crack it.
There have been many cases where different hackers have tried to break the 256 encryption and compromise the safety of documents but till now they have not been able to do so. This can give you an idea that how complicated and difficult it is, since there is no dearth of people who want to beak the encryption and compromise the data even if they do not want to steal anything but just for the fun. Till now this technology is holding up and going strong. But till how long it will be strong and not go obsolete is not known. Hackers world over are trying daily to break it and bring it down and we can hope only for the best so that all encrypted messages and data remains safe.
It is not that other methods of encryption are bad but due to data breaches and lot of hacking happening around the world it has become very important to have the best of the best applied for encrypted message and data safety. The main reason being that it gives more security to the users and more confidence the organisation handling all the data.
