How are prime numbers used in cryptology
WebIn general, the larger the key size used in PGP-based RSA public-key cryptology systems, the longer it will take computers to factor the composite numbers used in the keys. Accordingly, RSA cryptology systems derive their reliability from the fact that there are an infinite number of prime numbers—and from the difficulties encountered in factoring … Web19 de jan. de 2024 · Let's say I want to send you an encrypted message.
