The first thing we need is the data to encrypt. We call this data plaintext and it can be anything. Credit card information and grandma’s secret cookie recipe are both valid data we might want to encrypt. The second thing we need is a cryptographic key. A cryptographic key is a string...
BitLocker is a widely preferred tool for protecting local data. It can encrypt and decrypt a specific disk partition or the entire hard disk depending on your preferences. It uses the AES algorithm to encrypt and decrypt the data on the drives. VeraCrypt: VeraCrypt also uses the AES algorit...
Encryption keys are of two types: Symmetric encryption and Public key encryption. Symmetric encryption carries the same two keys being used for communication while in public key encryption; the key is distributed publicly for anyone to encrypt the message. Only the receiver has the access to the ...
A single algorithm is used to encrypt and decrypt a pair of keys. Each of these keys gets used for encryption and decryption. Let’s take a look at some of the common types of decryption algorithms that are used. Triple DES When hackers gradually learned to get past the Data Encryption ...

Technology is the magician behind the scenes. Computers use complex mathematical algorithms to encrypt and decrypt data. These algorithms create a lock and key system, where the encryption algorithm acts as a lock, and the decryption algorithm acts as the key. ...
Depending on which type of data encryption you use, you and the receiver might have to complete different steps to encrypt and decrypt the data properly. There are two common types of data encryption: Symmetric encryption. There is only one encryption key, or password, used in symmetric encrypt...
Learn what encryption is, how it works, and explore real-world examples in this guide. Understand the basics to safeguard your data and privacy.
DES is a deprecated symmetric key method of data encryption. DES works by using the same key to encrypt and decrypt a message, so both the sender and the receiver must have access to the same private key. DES has been superseded by the more secure AES algorithm. It was adopted by the ...
When encrypted data is intercepted by an unauthorized entity, the intruder has to guess which cipher was used to encrypt the data and what key is required to decrypt the data. The time and difficulty of guessing this information is what makes encryption such a valuable security tool. The more...
