错在题二,对于强抗碰撞性理解有误。
Sorry, something went wrong.
强抗碰撞性是指要找到散列值相同的两条不同的消息是非常困难的。

在Solidity语言中,最常用的哈希函数为____,它也是函数选择器所应用的函数。keccak-256 (這題答案很怪,最常用的是keccak256,但是只有sha256能正確執行,題目筆誤?)
下列关于这些特性中,描述不正确的一项是:对于一个哈希函数而言,强抗碰撞性比弱抗碰撞性更难满足
sha3-256("Hello world!") = 0xd6ea8f9a1f22e1298e5a9506bd066f23cc56001f5d36582344a628649df53ae8
sha3-256("Hello world.") = 0x28c9b96bc1e7fcda7f3356693de2a1781e25d76c468fc75b56450df4f25ca962
可以看到两者的结果相差极大。这主要归功于sha3-256良好的:灵敏性
