What is the difference between RSA and DSA keys?

Difference between RSA algorithm and DSA. 1. Rivest-Shamir-Adleman (RSA) algorithm : RSA stands for Rivest-Shamir-Adleman. It is a cryptosystem used for secure data transmission. In RSA algorithm, encryption key is public but decryption key is private. This algorithm is based on mathematical fact that factoring the product of two large prime ...

What is RSA and how does it work?

The RSA algorithm was published in the 70’s by Ron Rivest, Adi Shamir, and Leonard Adleman, hence RSA. RSA is an asymmetric system, which means that a key pair will be generated, a public key and a private key. More frequently it is used to encrypt and pass around symmetric keys which can actually deal with encryption at a faster speed.

How to encrypt and decrypt with RSA?

Encryption using RSA: To encrypt a plaintext M using an RSA public key we simply represent the plaintext as a number between 0 and N-1 and then compute the ciphertext C as: C = M e mod N. Decryption using RSA: To decrypt a ciphertext C using an RSA public key we simply compute the plaintext M as: M = C d mod N.
