The etymology from encrypt refers us to the English expression to encrypt, in turn derived from the Greek word enkrýptein (which can be translated as "hide" ). Specifically, that Greek term can establish that it is the result of the sum of two distinct components: the prefix "en-", which can be translated as "inside", and the verb "krypto", which is synonymous with " hide".
The encryption action consists of copy a message using a password .
It should be remembered that a key is a sign code which are interpreted according to certain correspondences and rules. When encrypting a text, a code is appealed so that its content is only accessible to those who know the rules governing the key in question.
To encrypt, in short, is to encrypt: that is, to transcribe a text in signs (letters, numbers, etc.) according to a certain code. In this way it is possible to protect your content.
It is called cryptography to the technique and the specialty consisting of encryption. Thanks to cryptography, you can transform a text with an encryption key, making it incomprehensible to those who do not have the key to decoded .
One of the simplest methods to encrypt a text is through the character substitution . Suppose we want to encrypt the following expression: “We will meet at the park at midnight today”. Appealing to encryption by substitution, we could transcribe the message by replacing each letter with the one that follows in the alphabetical order. The result would be the following: “Opt fodpousbsfnpt fo fm qbsrvf b mb nfejbopdif ef ipz”. As you can see, the message The result cannot be understood unless the decryption key is available, which implies replacing each letter with the preceding one in the alphabet.
Today, for example, you can resort to encrypting the different technological devices that are part of our lives. Thus, for example, there are those who choose to do that with their mobile phone as a way to ensure that there are no third parties who can access their data (bank details, contact phone numbers, email addresses, conversations, images and videos… ). That is, it protects them from any spy system and is also useful so that if someone steals the smartphone they cannot have free access to that information.
The way to encrypt a smartphone happens not only by setting a pattern or a PIN on the lock screen but also by using a password or betting on, from the "Security" option of the "Settings" section, to start the encryption process.
The only negative aspects of making the decision to encrypt the mobile phone is that its performance will be slower if it is a mid-low-end model and that it is a process that takes a long time. Moreover, it is also considered a disadvantage that if you wanted to restore encryption, what you would have to do is to restore the factory settings again.
