Cryptography is the basic technique of encrypting your data in order to keep it secure while being transferred to someone else. Today, we can witness some form of encryption being used in almost every Internet-based application.

However, there are lots of different types of cryptography. There are lots of complex algorithms, which can keep your data perfectly safe from the hands of cyber criminals. Mathematical formulas are used to encrypt your data and generate public and private keys.

Two of the most common types of cryptography used these days are symmetric and asymmetric encryption. Letâ€™s take a look at how both of these types of cryptography work, and which use cases are best for each one of them.

**Working**

IZpSymmetric encryption works by generating a secret key and encrypting your data with the help of that key. Any person with access to that secret key can decrypt the data.

On the other hand, asymmetric cryptography works by generating a public private key pair. The public key is used to encrypt the data, and the private key, which is shared between the sender and the receiver, can be used to decrypt the data.

**Use Cases**

Here are the use cases for symmetric encryption.

- One of the most common use cases of symmetric cryptography is the banking sector. Banks use this type of cryptography to encrypt your personally identifiable information.
- The best use case of symmetric encryption is storing data by encrypting it on your own computer.

Here are the use cases for asymmetric encryption.

- This type of cryptography is used in creating digital signatures, which can be used to verify the identity of the sender.
- Asymmetric encryption is also used in the Blockchain technology to verify and execute transactions.

These were some basic information about symmetric and asymmetric encryption, and their best use cases.
