SHA256 Hashing with two blocks：第一个块的哈希应该输入哪里？
SHA256 Hashing with two blocks: Where should the hash of the first block be inputed?
我刚刚实现了 SHA256 生成器，但遇到了多块问题。请问有谁能帮忙解答下这个问题吗？
为了便于检查，我们使用这个特定的文本输入：“致地球上的每一只野兽，每一只鸟”
因为这正好是448位，所以必须根据填充规则将其分成2块（长度字段只是少了一位）。
我一步一步的输出如下：
二进制的原始消息是：0,1,0,0,0,0,0,1,0,1,1,0,1,1,1,0,0,1,1,0 ,0,1,0,0,0,0,1,0,0,0,0,0,0,1,1,1,0,1,0,0,0,1,1,0,1 ,1,1,1,0,0,1,0,0,0,0,0,0,1,1,0,0,1,0,1,0,1,1,1,0,1 ,1,0,0,1,1,0,0,1,0,1,0,1,1,1,0,0,1,0,0,1,1,1,1,0,0 ,1,0,0,1,0,0,0,0,0,0,1,1,0,0,0,1,0,0,1,1,0,0,1,0,1 ,0,1,1,0,0,0,0,1,0,1,1,1,0,0,1,1,0,1,1,1,0,1,0,0,0 ,0,1,0,0,0,0,0,0,1,1,0,1,1,1,1,0,1,1,0,0,1,1,0,0,0 ,1,0,0,0,0,0,0,1,1,1,0,1,0,0,0,1,1,0,1,0,0,0,0,1,1 ,0,0,1,0,1,0,0,1,0,0,0,0,0,0,1,1,0,0,1,0,1,0,1,1,0 ,0,0,0,1,0,1,1,1,0,0,1,0,0,1,1,1,0,1,0,0,0,1,1,0,1 ,0,0,0,0,0,1,0,1,1,0,0,0,0,1,0,0,0,0,0,0,1,1,0,0,0 ,0,1,0,1,1,0,1,1,1,0,0,1,1,0,0,1,0,0,0,0,1,0,0,0,0 ,0,0,1,1,1,0,1,0,0,0,1,1,0,1,1,1,1,0,0,1,0,0,0,0,0 ,0,1,1,0,0,1,0,1,0,1,1,1,0,1,1,0,0,1,1,0,0,1,0,1,0 ,1,1,1,0,0,1,0,0,1,1,1,1,0,0,1,0,0,1,0,0,0,0,0,0,1 ,1,0,0,1,1,0,0,1,1,0,1,1,1,1,0,1,1,1,0,1,1,1,0,1,1 ,0,1,1,0,0,0,0,1,0,0,0,0,0,0,1,1,0,1,1,1,1,0,1,1,0 ,0,1,1,0,0,0,1,0,0,0,0,0,0,1,1,1,0,1,0,0,0,1,1,0,1 ,0,0,0

区块1的SHA256哈希值为：2,1,8,2,5,A,3,D,F,3,1,C,E,E,3,9,3,6,A ,D,A,F,C,3,6,0,F,8,0,F,9,8,8,0,C,5,8,D,2,F,F,E,C,3 ,4,4,A,8,2,9,D,F,6,8,2,F,2,5,D,F,6,D,C,D
谁能帮我解释一下这两个问题：
Block 1 的哈希值是否正确？
如果Block 1 hash全部正确无误，那么在Block 2 hashing即将开始的时候，这个hash number 21825A3D...应该输入哪里呢？
非常感谢您的帮助！
- Is the hash number for the Block 1 correct?
是的。恭喜。虽然这不是一个数字；它只是一个散列 value，因为二进制不代表单个数值。
- If Block 1 hash is all correct and good, where should this hash number
21825A3D... be inputed when Block 2 hashing is about to start?
有这些初始散列值，有时也称为常量。它们被命名为 h0..h7 in the pseudo-code of Wikipedia。您找到的中间散列应该替换它们。 h0..h7 也是最终哈希的输出（不幸的是，因为没有对哈希的最终操作允许长度扩展攻击）。
我刚刚实现了 SHA256 生成器，但遇到了多块问题。请问有谁能帮忙解答下这个问题吗？
为了便于检查，我们使用这个特定的文本输入：“致地球上的每一只野兽，每一只鸟”
因为这正好是448位，所以必须根据填充规则将其分成2块（长度字段只是少了一位）。

谁能帮我解释一下这两个问题：
Block 1 的哈希值是否正确？
如果Block 1 hash全部正确无误，那么在Block 2 hashing即将开始的时候，这个hash number 21825A3D...应该输入哪里呢？
非常感谢您的帮助！
- Is the hash number for the Block 1 correct?
是的。恭喜。虽然这不是一个数字；它只是一个散列 value，因为二进制不代表单个数值。
- If Block 1 hash is all correct and good, where should this hash number
21825A3D...be inputed when Block 2 hashing is about to start?
有这些初始散列值，有时也称为常量。它们被命名为 h0..h7 in the pseudo-code of Wikipedia。您找到的中间散列应该替换它们。 h0..h7 也是最终哈希的输出（不幸的是，因为没有对哈希的最终操作允许长度扩展攻击）。
