As with Apple’s two-step verification for Apple ID accounts, this Recovery Key is critical to retain. Warning 1! During the setup, OS X creates a Recovery Key for your drive.

(You can encrypt secondary and external drives by Control-clicking a drive’s icon and select Encrypt “Drive Name,” but it doesn’t tie in with login: you set a password for the drive, and have to enter it to mount it.) This comes with a few big flashing red warnings and pieces of advice before you proceed. On a system without FileVault 2 already in place, you need to turn it on, which converts your startup drive from its unencrypted state to fully encrypted. With FileVault 2 enabled, your computer boots into the Recovery volume, prompting you to login with any account that’s been allowed to start up the computer.

You’ll have an encrypted byte array now.OS X Recovery, a special disk partition that lets you run Disk Utility from the same drive you may be having trouble with, restore or install OS X via the Internet, restore a Time Machine backup, or browse Safari. We now only have to call one method on the cipherInstance to encrypt our message: cipherInstance.doFinal(bytesToBeEncrypted) We now have everything we need to encrypt our super secret message. GeneratePublic(new X509EncodedKeySpec(Base64.getDecoder().decode(publicKey))) Ĭipher cipherInstance = Cipher.getInstance(CIPHER_INSTANCE_TYPE) Key generatePublic = KeyFactory.getInstance(KEY_FACTORY_INSTANCE_TYPE). Then, initialise a Cipher with that instance of the Key class. For this, we first need to create an instance of the RSA key using the KeyFactory class. Next, we need to do some magic with the Java security package and generate an instance of the Cipher class. If you check the value of the publicKey variable now, you should see something like this: MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAut9/U5lR6UN/02YX79qviuKd2AQwEBiJMt15djesw6wgR/1jWJr/ZUM+XPIVkshHoPkhh2JhnqvEZt3VEYeYxy88xRksZqqEmgCwEX4gVsAWrGCTJ7U+LyuSYpavbHGcUkA4rIh9XCkgphvXYod2cnyU0XQJ1jRLvTD4EozTtyA1wKRxtATj/2o+swH3mnEW1y4weEoLmfcJ844tQU/l3DIxQh+XWhzdsqo8kX+Za8RAFbH2xbK+yG6U3it5TrSwmsSSUh2ZGlcGiN76C/426rTWS0lj5kYEUYKqON782ui8K2hGj9ylpL6lohosH8lsTKZvRK0PCs698QKrlc/MbwIDAQAB replaceAll(PUBLIC_KEY_END_KEY_STRING, EMPTY_STRING) replaceAll(PUBLIC_KEY_START_KEY_STRING, EMPTY_STRING) KeyString = keyString.replaceAll(NEW_LINE_CHARACTER, EMPTY_STRING) String keyString = new String(publicKey) Public static final String EMPTY_STRING = "" īyte publicKey = Files.readAllBytes(keyFile.toPath()) Public static final String PUBLIC_KEY_END_KEY_STRING = "-END PUBLIC KEY-" Public static final String PUBLIC_KEY_START_KEY_STRING = "-BEGIN PUBLIC KEY-"

For that, we’ll use the following code snippet: public static final String NEW_LINE_CHARACTER = "\n" For that, once we have the file’s content into a variable, we’ll replace all the unwanted text with some empty strings. You need to remove all that and have only the key.

We have to clean up the public key data though.
Next, we need to read the public key file into our Java code.
For that though, we need to first convert this string into a byte array: byte bytesToBeEncrypted = dataToBeEncrypted.getBytes() I have selected a very specific message to encrypt, and it makes a lot of sense: String dataToBeEncrypted = "Some random words in no particular order." Īs you can see, I can’t really send out this very sensitive message over public internet.
Now that we have a key pair, let’s start encrypting our message.
