In case you take cell safety significantly (and you must), then you definitely would possibly wish to take into account file encryption. I am not speaking about saving a file in an encrypted folder to tuck it away from prying eyes.
No. That is all about encrypting information you can both go away in your system and think about when wanted or share with others, understanding they are often considered solely by the recipient.
That is made doable by the OpenKeyChain app. This app is all about encryption, and though it makes the method simple, there are some belongings you’ll must know earlier than diving in.
Let’s do exactly that.
It is all about keys
In case you’ve ever used public key encryption in your desktop to securely ship a file to somebody, you already perceive it. If not, let me clarify.
Public key encryption makes use of a key pair: one personal and one public. The personal key stays on the recipient’s system, whereas the general public secret is despatched to those that must ship an encrypted file to them. Information encrypted with somebody’s personal key can solely be opened by somebody who has the corresponding public key. With out that public key, there is no option to open the file.
It really works, and it really works very nicely. You may have this on Android, and it is not practically as arduous as you would possibly assume. Let’s have a look at the way it works.
What you may want
To do that, you may want an Android system, and you will want the OpenKeyChain app put in. Be sure you set up that app, and also you’re able to go.
Handle the keys
There are two belongings you’ll want/wish to do. The primary is to create your individual key.
Open the Keys tab of the app. On that web page, faucet the three-dot menu within the upper-right nook after which faucet “Handle my keys.”
Present extra
On the ensuing web page, faucet CREATE MY KEY and stroll by the user-friendly wizard.

Import a public key
The subsequent factor it’s important to do is import the general public key from somebody you need/must ship an encrypted file to. That is the place OpenKeyChain actually shines. If the individual you could ship the encrypted file to additionally has OpenKeyChain put in, they’ll open their key, and you’ll merely scan the QR code related to their key pair so as to add their public key.
If the individual does not have OpenKeyChain put in, they must ship you their public key, and also you then must import it from inside My Keys > + > Import from File. Find the file the individual despatched you, after which it is prepared to make use of.
Encrypting a file
Together with your key created, now you can encrypt a file. You may both encrypt the file such that it will be despatched to a different consumer (utilizing the recipient’s public key), or you may encrypt a file that may be saved in your Google Drive account (or your system), utilizing your public key, such that the general public key password (that you just create inside the important thing creation wizard) is required to open the file.
One factor to remember with saving information to your system. These information will finish in .gpg. If somebody will get entry to your system, is aware of you will have OpenKeyChain put in, and is aware of the place these information are, they’ll view them with out coming into your decryption password (as a result of it will routinely match the important thing pair).
The excellent news is you can cover these information “in plain sight,” to make it more durable for somebody to seek out/view them. Also, these information can’t be considered by way of Google Drive, as a result of your public secret is saved in your system. Which means if somebody beneficial properties entry to your Google Drive account, they won’t be able to view these encrypted information.
To encrypt a file, observe these steps.
1. Open the Encrypt/Decrypt web page
Faucet the three-line menu on the primary web page after which faucet Encrypt/Decrypt.
2. Encrypt the file
On the ensuing web page, faucet Encrypt information. You’ll then have to pick who the file is to be encrypted for. In case you’re encrypting the file so it may be saved to Google Drive, you may use your key pair. In case you’re encrypting it for another person, you may have to pick their public key.
Both approach, faucet “Encrypt to” after which kind out the identify of the recipient. Choose the related key after which faucet “Add file(s).” Find the file you wish to encrypt, after which faucet the tiny save icon close to the highest proper (to the left of the share icon).
Choose the folder you wish to home the file, give the file a reputation, after which faucet Save. Your file will likely be saved within the supposed location. You may then ship the encrypted file to the recipient by no matter means you’d usually use (e-mail, messages, and many others).
Decrypting a file
That is easy. All it’s important to do is go to Encrypt/Decrypt, faucet “Choose enter file” underneath Decrypt/Confirm, after which find and faucet the file. You may open the file from inside OpenKeyChain, and also you’re good to go.
