It gives granular control over security measures as it allows for the encryption of individual files using a different key for each file. This demonstrates how encryption safeguards sensitive information by converting it into a format that cannot be read and understood by anyone without the necessary decryption knowledge and key.įile encryption or file-based encryption (FBE), as the name suggests, is a method of encrypting files individually in a file system. In this case, decrypting the encrypted text “v5u8/F28kOazjwQXTxY84+qeweiMvQ=” would yield the original text “I like apples” once again.Įncryption ensures that even if someone intercepts or gains unauthorized access to the encrypted text, they cannot understand its contents without the appropriate decryption process and key. ![]() Just like opening your closed house or car door with a unique key. Decrypting takes the encrypted text and applies the decryption algorithm, using the appropriate key, to transform the ciphertext back into the original plain text. To get the original text from the encrypted version, you simply need to reverse the encryption process, which is referred to as decrypting. The resulting encrypted text may look something like this: “v5u8/F28kOazjwQXTxY84+qeweiMvQ=.” As you can see, this encrypted text appears completely unreadable and incomprehensible, making it useless in the hands of a malicious attacker. You can use a data encryption software like AxCrypt which uses AES 256-Bit encryption algorithm to convert the text into an encrypted form. Suppose you have a piece of text that says, “I like apples,” and you want to encrypt it. Let's consider a simple example to understand encryption better. The same mathematical calculations are also used for decryption, which reverses the encryption process to change back the data to the original form. Just like the unique keys for your house or car, which can only unlock the specified door of the house or car. ![]() The process of rearranging and scrambling the data is done using complex mathematical algorithms using ‘cryptographic keys’ consisting of random and unique patterns of letters specifically associated with each encrypted file. This is achieved by running the data through an encryption algorithm, like Advanced Encryption Standard (AES), which randomly rearranges and jumbles up the information, rendering it incomprehensible and unreadable after the process. Encryption is a cryptographic process that transforms comprehensible and intelligible data into a scrambled and unreadable form called ciphertext.
