RSA Encryption Implementation Without Using Library in Python How does RSA algorith work? Since this is asymmetric, nobody else except the browser can decrypt the data even if a third-party user has a public key in the browser. This is also known as public-key cryptography because one of the keys can be given to anyone. Companies such as Acer, Asus, HP, Lenovo, etc., use encryption techniques in their products. It is an asymmetric cryptographic algorithm which means that there are two different keys i.e., the public key and the private key. This algorithm is used by many companies to encrypt and decrypt messages. RSA abbreviation is Rivest–Shamir–Adleman. Encryption What is RSA Encryption in python?
