Top 15 Apps Similar to Cryptography Interview Q&A

This app performs 5 fundamental calculationsinnumber theory. These form a basis for many algorithmsincryptography and computer security. They are:1. Determine if number is prime, or find the smallestprimefactor if it is not prime. This can be used repeatedly to findallthe prime factors of a number.2. Find the gcd(m,n) (greatest common divisor) and lcm(leastcommon multiple) of two integers, i.e. the largest integerthatdivides both numbers.3. Compute a number mod n, (modular arithmetic), or anumberraised to a power mod n, i.e. modular exponentiation a^b modn. Forexample 2^50 mod 15.4. Compute the modular inverse of a number, i.e. solve a*x =1mod n, for integer x, given a and n.5. Find integer solutions x, y to Diophantine equations,i.e.equations of the form ax + by = c, where a, b, c areallintegers.This app does not display any ads.Please submit your comments/suggestions to improve this appforfuture versions.
