RSA Encryption and Decryption : DigInfo

DigInfo – http://movie.diginfo.tv

Cryptology has grown from the simple to the increasingly complex but it’s main function still remains the same- to send a message safely and securely. With computers comes increasingly powerful encryption technology required to maintain this security.
RSA is currently the most popular algorithm (or mathematical formula) for public-key cryptography.
Here students at an event sponsored by NiCT (National Institute of Information and Communications Technology) are computing the RSA algorithm mathematically to send and receive messages.
RSA first came to light in 1977 and is comprised of a public key and a private key. The public key is available to everyone and hence it’s used to encrypt messages and mark them so they are sent to a specific destination. The message can only be decrypted using the matching private key and this key is held securely at the messages destination.
Even though the RSA algorithm is a publicly available document- RSA encryption is used on a daily basis and is the foundation of modern electronic encryption.
