A public key encryption algorithm developed by Ronald Rivest,Adi Shamir, and Leonard Adleman in 1978 that became a de facto standard. RSA formed the basis for a number of encryption programs, including Pretty Good Privacy (PGP). Current versions of RSA employ a 128-bit encryption algorithm, which is computationally infeasible to decode without the key.The 40-bit export version is not considered highly secure. See also encryption, PGP, public key encryption, and standard.
An algorithm used in public key cryptography, commonly used on the Internet in various protocols for secure transmission of data.
Origin of rsa
- From the initial letters of the surnames of its inventors, Ronald Rivest (born 1947), American cryptographer Adi Shamir (born 1952), Israeli cryptographer and Leonard Adleman (born 1945), American computer scientist
