公司老項目使用grails2.0+
版本,他的加密方式爲encodeAsSHA256
,數據是經過導入實現,要兼容之前數據加密方式,使之前使用老項目的用戶也能用原先的密碼登陸。
def test() { map.password1 = "123456".encodeAsSHA256() map.password2 = springSecurityService.encodePassword("123456") render map as JSON }
src/main/goovy
下建立CustomPasswordEncoder.groovy
類,也能夠建立java
類package com.encoder import org.springframework.security.authentication.encoding.MessageDigestPasswordEncoder import org.springframework.security.authentication.encoding.PasswordEncoderUtils import org.springframework.security.crypto.codec.Hex import org.springframework.util.Assert import java.security.MessageDigest /** * 自定義加密覆蓋默認加密方式 * 項目spring-security版本爲3.1.0,本能夠從新BaseDigestPasswordEncoder類 * 可是本人看BaseDigestPasswordEncoder類被標記爲刪除了,因此經過重寫MessageDigestPasswordEncoder類方法實現 */ class CustomPasswordEncoder extends MessageDigestPasswordEncoder { // 默認爲MD5 private String algorithm = "MD5"; // 加密次數(提升安全) private int iterations = 1; CustomPasswordEncoder() { // 當前類默認構造器,由於父類沒有空構造器,因此這裏必須調用父類有參構造,這裏傳入參數必須是父類存在的加密規則,不然報錯 super("SHA-256") } CustomPasswordEncoder(String algorithm) { super(algorithm, false); this.algorithm = algorithm } CustomPasswordEncoder(String algorithm, boolean encodeHashAsBase64) throws IllegalArgumentException { super() setEncodeHashAsBase64(encodeHashAsBase64); this.algorithm = algorithm; getMessageDigest(); } @Override String encodePassword(String rawPass, Object salt) { String saltedPass = this.mergePasswordAndSalt(rawPass, salt, false) MessageDigest messageDigest = this.getMessageDigest() byte[] digest = messageDigest.digest(saltedPass.getBytes("UTF-8")) for (int i = 1; i < iterations; i++) { digest = messageDigest.digest(digest); } // 先判斷是否啓用base64 if (this.getEncodeHashAsBase64()) { return new String(Base64.encodeAsBase64(digest)) // 判斷是否爲自定義的SHA-256-1(框架自定加密方式,非spring security框架,這裏指的是grails自帶的加密) } else if ("SHA-256-1".equalsIgnoreCase(algorithm)) { return rawPass.encodeAsSHA256() } else { // 使用用戶配置的其餘加密方式 return new String(Hex.encode(digest)) } } @Override boolean isPasswordValid(String encPass, String rawPass, Object salt) { String pass1 = "" + encPass String pass2 = encodePassword(rawPass, salt) return PasswordEncoderUtils.equals(pass1, pass2) } String getAlgorithm() { return algorithm; } void setIterations(int iterations) { Assert.isTrue(iterations > 0, "Iterations value must be greater than zero"); this.iterations = iterations; } }
grails-app/conf/spring/resources.groovy
中註冊一下bean
beans = { // 自定義密碼 passwordEncoder(com.encoder.CustomPasswordEncoder) { encodeHashAsBase64 = false // 若爲true,則以base64方式加密 } }
grails-app/conf/application.groovy
中添加配置// 原框架加密方式,有SHA-25六、bcrypt、MD五、pbkdf2,默認爲bcrypt // 自定義加密默認爲MD5,這裏SHA-256-1爲自定義加密,還能夠用SHA-256等 grails.plugin.springsecurity.password.algoritham = 'SHA-256-1'
domain.save(failOnError: true)
的有時須要修改成domain.save(flush: true)
,我測試密碼修改時,failOnError: true
沒有修改爲功。參考java
