Demystifying symmetric and asymmetric encryption

Here is an overview of the two types of encryption which is the backbone of the Cyber Security Industry to protect your data.

It is important to understand the basics of the technology behind encryption which will help you choose the right Data Security Partner. The two main types of encryption used today are symmetric and asymmetric encryption.

What is encryption?

Encryption is the process which converts the original representation of information into an alternative form known as cipher text.

What is end-to-end encryption?

End-to-end encryption (E2EE) is a system of communication where only the communicating users can read the messages. This kind of encryption prevents any third party from eavesdropping on your data keeping it safe and private at all times.

What is Symmetric Encryption?

In symmetric encryption the same key is used to encrypt and decrypt information. It uses the Advanced Encryption Standard (AES 256) which makes it hard to decode. The sender and receiver have to agree on a key before sending the data back and forth. It also requires a safe method to transfer the key from one party to another. While this makes it easier to use, it makes it less secure.

What is Asymmetric Encryption?

Asymmetric encryption uses both public and private keys to encrypt and decrypt data. While public key is available to both parties, private key is unique to each user. This is more secure than symmetric encryption but is slower.

While asymmetric encryption has been out there for a long time, it is not until recently that it has been simplified to be used widely.

What encryption does DropSecure use?

Here at DropSecure we use a combination of both symmetric and asymmetric encryption. This gives us the ability to optimize your data sharing experience with utmost security.
