WebOct 16, 2015 · As for whether collisions are possible- modern key sizes (depending on your desired security) range from 1024 to 4096, which means the prime numbers range from 512 to 2048 bits. That means that your prime numbers are on the order of 2^512: over 150 digits long. We can very roughly estimate the density of primes using 1 / ln (n) (see here ).
