The public key can also be used to encrypt a message to send to the private key owner that no one else can decrypt. It also means you can verify that the message came from the owner of the private key. The great thing about this is the public key can be known by everyone an can be used to decrypt messages from the owner of the private key. RSA is a public-key encryption system where an encryption/decryption key is published for everyone to know and a second decryption/encryption key is kept secret or private. ![]() The RSA algorithm was published in in 1977, but again, there was an equivalent system that was developed by the British signals intelligence agency (GCHQ) in 1973 1, but they kep this a secret. He is also the co-discoverer fo the Adleman–Pomerance–Rumely primality test. Leonard Adleman is widely referred to as the Father of DNA Computing, where DNA is used to compute an algorithm. 2Īdi Shamir was a co-discoverer of Differential Cryptanalysis, which was later revealed to have been already known by IBM and the NSA. Ronald Rivest also invented RC2, 4, 5 and 6 symmetric key encryption algorithms as well as the well the MD2, 4, 5 and 6 family of hash functions. RSA is an acronym made up from the surnames of its inventors 1: ![]() View Learn Encryption with Python on GitHub RSA Encryption and Decryption
