Anti-database theft-Web Front-end slow Encryption

database leakage scenarios. 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
