WebMay 12, 2024 · RSA (Rivest–Shamir–Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and it is different from the decryption key which is kept secret (private). You can read more about RSA here. Why Dummy code ? WebIn RSA typically e has only a small number of 1-bits in its binary representation, because there is no calculation to do for 0-bits. Thus, e = 3 = 11b or e = 65537 = 10000000000000001b are common. – user448810 Apr 25, 2014 at 1:23 @user3423572: I still had it wrong; the dyslexia must be strong dotay. It's fixed now, I hope.
