PHP常见的几种加密方式

password_hash 函数

password_hash 用于创建密码的散列

echo password_hash("123456", PASSWORD_DEFAULT);

# $2y$10$UDsDSviXPHSYFryVTbX0OuXNYKxr9xeRuwqy2p7OfXjxh95JBL/LW

校验密码

$password = "$2y$10$8Bs9WdtSwVGuIsEdiEWqj.5YOsU1bmEDmbx3DjfPgoIdmRcQD6p66";

var_dump(password_verify("123456",$password));

# bool(true)

md5 函数

md5函数用于计算字符串的MD5散列

echo md5("123456");

# e10adc3949ba59abbe56e057f20f883e

md5_file函数可对文件进行MD5散列计算

base64 加解密

base64_encode和base64_decode函数可对数据进行编码，结果为字符串，失败时返回false

# base64_encode 加密

echo base64_encode("123456");

# MTIzNDU2

# base64_encode 解密

echo base64_decode("MTIzNDU2");

# 123456

urlencode与urldecode

urlencode和urldecode可对URL进行编码和解码

echo urlencode("https://www.baidu.com/?a=1");

# https%3A%2F%2Fwww.baidu.com%2F%3Fa%3D1

echo urldecode("https%3A%2F%2Fwww.baidu.com%2F%3Fa%3D1");

# https://www.baidu.com/?a=1

3DES加密解密

$key = "abcdefg";

echo base64_encode(openssl_encrypt("1234567890", 'des-ede3', $key, OPENSSL_RAW_DATA));

# hgK3i8hbUeW+jrPtHBcWsQ==

echo openssl_decrypt(base64_decode("hgK3i8hbUeW+jrPtHBcWsQ=="), 'des-ede3', $key, OPENSSL_RAW_DATA);

# 1234567890
