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...
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 ...
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...
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...
Symmetric encryption: Encrypts and decrypts data by using a secret symmetric key that is shared by all the parties that are involved in a transaction. Asymmetric encryption (also known as public key encryption and public key cryptography): Encrypts and decrypts data by using two different keys...
Hypertext transfer protocol secure (HTTPS) employs encryption to protect data transmitted between a user's browser and a website. It uses secure sockets layer/transport layer security (SSL/TLS) protocols to encrypt the connection, ensuring that sensitive information, such as login credentials, remains...
