Asymmetric Encryption. RSA (Rivest-Shamir-Adleman) is an asymmetric encryption algorithm that uses two different keys: a public key and a private key. Data encrypted with the public key can only be ...

This repository contains implementations of various cryptographic algorithms in Java, including AES, DES, RSA, SHA, Triple DES, IDEA, ECC, SHA-256 ... only the recipient's private key will decode it — ...

RSA in action. Let’s follow the RSA algorithm step by step, with an example. Let’s say Bob wants to send a private message to Alice. The first step is for Alice to generate the keys, both ...

Cryptography is the art of keeping information secret and safe by transforming it into form that unintended recipients cannot understand. It makes secure data transmission over the internet possible.

Private-key cryptography has been used for ages, especially on the battlefield. It employs a shared-secret key for communication. By contrast, public-key cryptography, invented in the mid-1970s ...

Encryption has come a long way since the days of Sparta and Rome, but it’s still not 100% secure.
