0x0C multi-thread slow Encryption
User Configuration is getting better and better, many of which are quad-core and eight-core processors. Can I use the advantages of multithreading to break down slow encrypted computing? If each computing step depends on the previous results, it cannot be disassembled. For example:
for i =0~10000
x = hash(x)
end
This is a serial computing. However, only parallel tasks can be divided into multiple small tasks. However, another me

Apparently, I used dijstra a long time ago,
Now I am a beginner in spfa. I will use it to train my hands and basic algorithms. I don't want to explain it anymore...
