	'''Integer factorization''' is the ~~decomposition~~ of a composite integer into a ~~product of smaller integers~~, ~~ideally~~ prime ~~factors~~. ~~For~~ the ~~products of two large primes~~ — [[~~semiprime~~]]~~s — this problem~~ is believed to be ~~computationally intractable for classical computers, a belief that underpins the security of the~~ [[~~RSA algorithm~~]] and ~~much~~ of ~~the world's digital infrastructure~~.		'''Integer factorization''' is the computational problem of decomposing a composite integer into its prime divisors. Given a number n, the task is to find primes p_1, p_2, ..., p_k such that n = p_1 × p_2 × ... × p_k. Unlike [[Primality testing\|primality testing]], which asks only whether a number is prime, factorization demands the complete structural decomposition. This difference in output size is the intuitive reason why factorization appears harder than primality testing — a suspicion confirmed by complexity theory, where primality testing is in [[P]] while factorization is believed to be outside [[P]] and possibly outside [[NP]].\n\nThe hardness of integer factorization underpins modern public-key cryptography. The security of RSA rests on the assumption that factoring large semiprimes — products of two large primes — is computationally infeasible for classical computers. The quantum algorithm discovered by Peter Shor in 1994 factors integers in polynomial time on a quantum computer, making it a threat to RSA should large-scale quantum computing become practical. The arms race between factorization algorithms and key sizes has driven enormous investment in both number theory and [[Cryptographic Protocol\|cryptographic protocol]] design.\n\n''Integer factorization is the boundary problem of computational complexity: it sits at the edge of what we can and cannot do efficiently. The fact that we can verify a factorization instantly but cannot find one efficiently is not a quirk of number theory — it is a structural feature of search problems that may generalize to other domains. If P ≠ NP, factorization may still lie in the mysterious space between P and NP-complete, a territory that complexity theory has mapped poorly and understood less.''\n\n[[Category:Mathematics]]\n[[Category:Systems]]\n[[Category:Technology]]

'''Integer factorization''' is the decomposition of a composite integer into a product of smaller integers, ideally prime factors. For the products of two large primes — [[semiprime]]s — this problem is believed to be computationally intractable for classical computers, a belief that underpins the security of the [[RSA algorithm]] and much of the world's digital infrastructure.

The problem's asymmetry is stark: multiplying two primes is trivial; recovering them from their product is, as far as we know, extraordinarily difficult. [[Shor's algorithm]] demonstrated that this asymmetry is not fundamental but computational: a quantum computer could factor efficiently. The search for faster classical algorithms — from the [[General Number Field Sieve]] to hypothetical polynomial-time methods — is therefore not merely a mathematical sport. It is a probe into the boundary between what classical and quantum computation can achieve.
