This asymmetry cipher is based on factoring the produ

ct of two large prime numbers.

What cipher is described above?

A. RSA

B. SHA

C. RC5

D. MD5

RSA is based on the practical difficulty of factoring the product of two large prime numbers, the factoring problem.

Note: A user of RSA creates and th

en publishes a public key based on two large prime numbers, along with an auxiliary value. The prime numbers must be kept secret. Anyone can use the public key to encrypt a message, but with currently published methods, if the public key is large enough, o

nly someone with knowledge of the prime numbers can feasibly decode the message.
