In plain words
MemSafeCrypto is a Java library that provides cryptography primitives built with DirectByteBuffer for memory-safe operations. It's designed for developers who need to implement cryptographic functions in Java while minimizing exposure of sensitive data in memory. The library's use of DirectByteBuffer allows it to manage cryptographic keys and data outside the garbage-collected heap, reducing the risk of sensitive information lingering in memory.

I built this machine so I could generate Bitcoin keys that I could trust. Air-gapped and simple to use and understand (mechanical). The Satoshi 9000 demo: https://youtu.be/bJiOia5PoGE The key value proposition of the machine is that it generates analog randomness in the physical world and converts it into digital (1’s and 0’s) randomness. Seamlessly. But it occurs to me that it may have other uses beyond crypto keys for your own use, such as: * Randomized clinical trials. Clinical trials need a high degree of transparency for ethical reasons; also, for legal reasons should it…
