Go 常见hash算法示例

包含了md5,sha256,sha512,sha3_512,black2s,black2b等hash算法示例。
代码:

package main

import (
    "crypto/md5"
    "crypto/sha256"
    "crypto/sha512"
    "fmt"

    "golang.org/x/crypto/blake2b"
    "golang.org/x/crypto/blake2s"
    "golang.org/x/crypto/sha3"
)

func getHash(input string, hashType string) string {
    switch hashType {
    case "MD5":
        return fmt.Sprintf("%x", md5.Sum([]byte(input)))
    case "SHA256":
        return fmt.Sprintf("%x", sha256.Sum256([]byte(input)))
    case "SHA512":
        return fmt.Sprintf("%x", sha512.Sum512([]byte(input)))
    case "SHA3_512":
        return fmt.Sprintf("%x", sha3.Sum512([]byte(input)))
    case "BLAKE2s_256":
        return fmt.Sprintf("%x", blake2s.Sum256([]byte(input)))
    case "BLAKE2b_512":
        return fmt.Sprintf("%x", blake2b.Sum512([]byte(input)))
    default:
        return fmt.Sprintf("%x", sha256.Sum256([]byte(input)))
    }
}

func main() {
    fmt.Println("go md5,sha256,sha512,sha3_512,blake2s_256,blake2b_512 hash demo")
    fmt.Println("MD5:", getHash("https://const.net.cn/", "MD5"))
    fmt.Println("SHA256:", getHash("https://const.net.cn/", "SHA256"))
    fmt.Println("SHA512:", getHash("https://const.net.cn/", "SHA512"))
    fmt.Println("SHA3_512:", getHash("https://const.net.cn/", "SHA3_512"))
    fmt.Println("BLAKE2s_256:", getHash("https://const.net.cn/", "BLAKE2s_256"))
    fmt.Println("BLAKE2b_512:", getHash("https://const.net.cn/", "BLAKE2b_512"))
}

输出：
