将任意长度的二进制值串映射为固定长度的二进制值串，这个映射的规则就是哈希算法，而通过原始数据映射之后得到的二进制值串就是哈希值。 构成哈希算法的条件： 从哈希值不能反向推导出原始数据（所以哈希算法也叫单向哈希算法） 对输入数据非常敏感 ...

Many discussions of “hybrid encryption” begin with some debate about just what this means. Hybrid encryption in general refers to the combined use of public-key (asymmetric) cryptography with ...

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm ...

Bitcoin offers an irreversible digital property function that prior to its invention simply did not exist. Understanding Bitcoin is a one-way hash function should make sense because a hash function ...

You might not have realized it, but the next great battle of cryptography began this month. It's not a political battle over export laws or key escrow or NSA eavesdropping, but an academic battle over ...

IOTA Foundation, the company wanting to be the cryptocurrency for the Internet-of-Things (IoT), has just launched a new hash function, and it’s dishing out shares of a $220,000 (200,000 euro) bounty ...
