Still, it is much slower than symmetric encryption. Note that since asymmetric encryption doesn’t share the encryption key, it’s more secure than symmetric encryption. Here is an article where I have discussed about AES encryption in Java This type of encryption uses a single key known as private key or secret key to encrypt and decrypt sensitive information. We have another encryption technique called as Symmetric encryption.

The example shown here can be used to generate base64 encoded public keys and the same keys can be shared with javascript or Android client to encrypt all the request that has to travel through the wires to reach to the server and the server can decrypt that using the private key. Asymmetric encryption is mostly used when there are 2 different endpoints are involved such as VPN client and server, SSH etc. Here, you can encrypt sensitive information with a public key and a matching private key is used to decrypt the same. Asymmetric encryption uses two different keys as public and private keys. You can use this online tool for generating RSA keys and perform RSA encryption and decryption online.Īs we know, there are 2 basic types of encryption - Asymmetric and Symmetric encryption. We will be generating public and private keys using KeyPairGenerator and use these keys for asymmetric encryption and decryption. In this article, we will discuss about RSA(Rivest–Shamir–Adleman) cryptography encryption and decryption in java.
