eli5 can someone explain to me what the RSA algorithm in cybersecurity is please
In: 7
The RSA algorithm is a public-key cryptography algorithm that is used in many different applications, including securing communications and digital signatures. It is named after its inventors, Ron Rivest, Adi Shamir, and Len Adleman.
RSA works by using a large prime number to generate a public and private key pair. The public key can be used to encrypt messages, and the private key can be used to decrypt them.
To encrypt a message, the sender first generates a random number, called a “session key.” This key is then used to encrypt the message using a symmetric-key algorithm, such as AES. The encrypted message and the session key are then both encrypted using the recipient’s public key.
To decrypt the message, the recipient first decrypts the session key using their private key. They can then use the session key to decrypt the message using the symmetric-key algorithm.
