原始场景：我把 1TB PT 站下的种子（明文）+4TB 的硬盘内容（包含前面的那 1TB ，不要问为什么）用 rclone AES 加密后（密文）一起备份到百度网盘

 | 2 hcocoa Jan 31, 2023 道理我都懂，而且楼上说的没错，但是多少种子加起来有 1TB |
 | 3 tuwulin365 Jan 31, 2023 谁会那么费力解密你的种子啊[二哈] |

The nonce is incremented for each chunk read making sure each nonce is unique for each block written. The chance of a nonce being re-used is minuscule. If you wrote an exabyte of data (10 bytes) you would have a probability of approximately 2×10 of re-using a nonce." 几 PB 而已，对于现代加密算法洒洒水啦~ |
