Web), users may solve puzzles using cryptographic hash functions in hopes of being rewarded with a fixed amount of the cryptocurrency. However, blockchain technology may be more broadly applicable than cryptocurrencies. In this work, we focus on the cryptocurrency use case, since that is the primary use of the technology today; however, there is WebAnother approach would be to choose a random e, compute the gcd of e and O(n) using the Euclidean algorithm, and then divide e by this gcd. Then one would compute a corresponding d using, perhaps, the Euclidean algorithm. Of course, computing O(n) is no problem - of one knows p and q. Using the RSA Algorithm to Send Messages
