Countless messages and e-mails are written every day all over the world using various programs and then sent directly. However, many people do not even know that their messages can be read because they are not encrypted. If so, these messages are traveling over the unencrypted internet.
So if you want to post private information/content, you should make sure you use encryption to prevent others from reading it. It is important to be informed about this, because as everyone knows, “the internet never forgets” and you should be careful when sending sensitive data.
How does encryption work?
Basically, the encryption method consists of two components, which are the cryptographic algorithm and one secret key. The algorithm describes the encryption method and the key provides parameters. Encryption makes it possible to turn plaintext into so-called “ciphertext”, which seems like nonsense.
Even at that time in ancient Egypt, important messages were written down so that they could not be read.
Even then, the point was that there was a fear that the matter might fall into the wrong hands.
Today, message encryption is used mainly for sending messages over the Internet. For example, when writing e-mails, it is possible for private messages to be sent directly from the sender to the recipient without anyone else being able to access and read them except the two people. You need a “key” for this.
The encryption methods used today are secure. Attempting to break such a “key” is impossible, because it is impossible with available computer systems.
With modern methods of writing (encryption – encryption) they are used for digital keys in sequential ways. For security, an important level of encryption is the length of bits.
What types of encryption are available?
Basically, there are two types that are distinguished from each other. There is symmetric encryption, which uses the same private key for encryption and decryption.
Then there is asymmetric encryption, which uses a different key to encrypt the plaintext than to decipher the password. With this method, the secret key is public and therefore known to other users. The key used for encryption, on the other hand, is private.
How does end-to-end encryption work?
When encryption works, every email, electronic mail or chat message is encrypted so that only the sender and recipient can read the message in plain text. For this reason you need a key, only with this it is possible to read and hear text messages in plain language.
Therefore, this encryption provides maximum security and privacy.
In addition, sender authentication is verified, which verifies that the sender is the person they claim to be. Integrity cannot be changed with this method, because it is impossible for the messages to be changed anonymously by other people.
What should you consider when hiding?
It is imperative that encryption be used at all times. If you have little or no experience, email programs and other helpers can often help make the setup easier. What also provides good security is the digital signature, which can be reused.
This can also help ensure that you are communicating with the right person.
Not only people, but also companies are careless with their messages and emails. Some people do not hide their messages. It is important to draw attention to the value and importance of encryption. After all, important data and information should get into the right hands and not be misused for other purposes.
Other privacy options
There is also a way to transfer data through so-called file storage or cloud storage services. This is a storage facility in the cloud. Dropbox, for example, is known as a public cloud.
Such services provide the opportunity to store content on a cloud server, which only the creator has access to. You can then create folders, copies and documents for other people to access. For this reason it is necessary to release the folder to authorized users.
It is also possible to reduce the time, for example you can reduce the time by one or two days. So there is no chance for a hacker to access the content.
