WebApr 10, 2024 · I need to generate cryptographically strong random alphanumeric strings with a specified length, only using the following characters. A-Z a-z 0-9 Is there a way to accomplish this in C#? WebThis technique is called Cryptographically Generated Addresses (CGAs). CGA provides the ownership proof necessary for an IPv6 address without relying on any trust authority. However, the CGA’s computation is very high, especially for a high security level defined by the security parameter (Sec).
