Secure Digital Assets using RSA Encryption

Security of all kinds is very important in the present world when it comes to digital assets security and your data security is very important in the current world. everything is online and anyone can access your personal or important information unless it is secured.

There are many ways to secure your digital assets, encryption is one of them. depending on the kind of data we have, we apply different kinds of algorithms to protect our data.

We use different ways like Encoding, Encryption, Hashing, etc. All these are very helpful. In this article, I will talk about encryption. We have multiple types of encryption algorithms RSA Algorithm is very famous and I will talk about it.

RSA Algorithm: In this algorithm, There are 2 keys private key and a public key. To communicate with others in a secure manner. we have to keep our private keys safe and we can give our public keys to others for encrypting our data. One thing to keep in mind we can generate the public key with our private key but we can not generate a private key with our public key. With this in mind and also for one private key there will always be one public key.

Anyone with our public key can encrypt the data and send it to us and we can decrypt that with our private key. and if we have to send the data to others then we will encrypt the data and send it to others and they can decrypt it with or public key.

After encryption data format becomes cipher text and it is very long bits. so we need to send it to others after encoding it to base 64 formats. While decrypting person has to decode first base 64 to cipher text and then decode it from cipher text to plain text which humans can understand.

This can easily be achieved in any programing language. We work mostly in Java and Golang so I am attaching the link to my GitHub repository for developers to understand the working model.

We have made this example in java spring boot and as a rest service, so you can use it like a service and encrypt any data, and also you can decrypt any data.

please remove our private key and public key and use your own keys for encryption and decryption. if you need any technical assistance mail us at [email protected]
