Encryption is the process through which data is secured through cryptographic measures. There are lots of ways through which encryption is reached. One of the important types of encryption is asymmetric encryption. This is also termed as public key cryptography.
In contrast to normal encryption, asymmetric encryption uses two keys, one public and one private, to encrypt and save data. This pair of keys is the main thing used to achieve encryption in asymmetric encryption.
Let’s take a look at the role of both of these keys in asymmetric encryption.
Working of Asymmetric Encryption
As we have already mentioned above, asymmetric encryption is achieved by using a pair of private and public keys. This system uses the public key to encrypt the data, and the private key is used to decrypt the same data. Private key is exclusive to the sender and the receiver, and no one else can access it.
For example, if you want a field agent to send you regular reports, you can use a pair of public and private keys to keep the data between you and the agents secure. For example, the agent can use the public key to encrypt the information they are sending you, and you have access to the private key, which is a must, if you want to decrypt the information received. This type of one-way communication can make hacking almost impossible for anyone.
Creating The Keys
Platforms like IZpAsymmetric encryption use the standard cryptographic methods to create the pair of keys. A protocol is used by the asymmetric systems to create the pair of keys automatically. Both the private and public keys are connected with each other through a mathematical algorithm. Every algorithm is different from the other one, and ensures the security of encrypted data.
