is created by hashing the image data. SHA-1 is overkill but easy; just a few bytes of hash are good enough for our purpose. // keyOf returns (part of) the SHA-1 hash of the data, // as a hex string.

"one-way" in one-way hashing. Commonly used cryptographic, one-way hash algorithms include SHA- 256, SHA-1, MD5 and so on. You can easily use the three aforementioned hashing algorithms in Go as follows:

目前用的最多的密码存储方案是将明文密码做单向哈希后存储，单向哈希算法有一个特征：无法通过哈希后的摘要 (digest)恢复原始数据，这也是“单向”二字的来源。常用的单向哈希算法包括SHA-256, SHA-1, MD5等。 Go语言对这三种加密算法的实现如下所示： //import "crypto/sha256" h := sha256.New() io.WriteString(h, "His
