前言
本文主要给大家介绍了关于spring security 5.x实现兼容多种密码的加密方式，分享出来供大家参考学习，下面话不多说了，来一起看看详细的介绍吧。
1、spring security PasswordEncoder
spring security 5不需要配置密码的加密方式，而是用户密码加前缀的方式表明加密方式，如：
- {MD5}88e2d8cd1e92fd5544c8621508cd706b代表使用的是MD5加密方式；
- {bcrypt}$2a$10$eZeGvVV2ZXr/vgiVFzqzS.JLV878ApBgRT9maPK1Wrg0ovsf4YuI6代表使用的是bcrypt加密方式。
spring security官方推荐使用更加安全的bcrypt加密方式。
这样可以在同一系统中支持多种加密方式，迁移用户比较省事。spring security 5支持的加密方式在PasswordEncoderFactories中定义：

public class PasswordEncoderFactories { public static PasswordEncoder createDelegatingPasswordEncoder() { String encodingId = "bcrypt"; Map<String, PasswordEncoder> encoders = new HashMap(); encoders.put(encodingId, new BCryptPasswordEncoder()); encoders.put("ldap", new LdapShaPasswordEncoder()); encoders.put("MD4", new Md4PasswordEncoder()); encoders.put("MD5", new MessageDigestPasswordEncoder("MD5")); encoders.put("noop", NoOpPasswordEncoder.getInstance()); encoders.put("pbkdf2", new Pbkdf2PasswordEncoder()); encoders.put("scrypt", new SCryptPasswordEncoder()); encoders.put("SHA-1", new MessageDigestPasswordEncoder("SHA-1")); encoders.put("SHA-256", new MessageDigestPasswordEncoder("SHA-256")); encoders.put("sha256", new StandardPasswordEncoder()); return new DelegatingPasswordEncoder(encodingId, encoders); } private PasswordEncoderFactories() { }} |
