解决方案

是否有可用的现有可信工具或库？请尝试随机.ORG 。他们有各种免费（和付费）服务，根据大气噪声生成真正的随机数（或者至少这是他们声称做的）。

I need to create a one-time pad to encrypt some data (a few KBs in size). How should I go about generating this one-time pad to avoid all of the pseudo-random problems associated with basic random number generation such as rand()?

Is there an existing, trusted tool or library I can use for this?

解决方案

Try Random.ORG. They have various free (and paid) services that generate truly random numbers based on atmospheric noise (or at least that is what they claim to do).
