The problem with this algorithm is that it’s not cryptographically strong. In other words, the generated values are much more predictable, therefore attackers could use it to compromise our system. WebAug 25, 2016 · All PRNGs are not created equal Luckily, for these security-centered scenarios you have the option of cryptographically secure pseudorandom number generators (CSPRNGs). These are designed to resist a would-be attacker’s ability to identify the seed value and predict subsequent outputs in a sequence. edwardjones.com careers login
