RSA Full Form: History of RSA
RSA, which stands for Rivest-Shamir-Adleman, is a clever way to keep digital information safe. Imagine it’s like a super-secret lock and key for your online messages and transactions. It all started back in the 1970s when three smart folks named Ron Rivest, Adi Shamir, and Leonard Adleman came up with this idea.
