使用jasypt-1.5加密Spring的db属性文件.doc

使用jasypt-1.5加密Spring的db属性文件 (如perties) 工具包准备: /index.html /maven2/org/jasypt/jasypt/1.5/ /encrypting-configuration.html 下载工具包后，会用到几个jar: jasypt-1.5.jar icu4j-3.8.jar　可另外下载 commons-lang-2.1.jar commons-codec-1.1.jar jasypt-cli-bundle.jar　 配置环境变量： JASYPT_HOME=C:\Java\jasypt-1.5 2.JASYPT_CLASSPATH=.;%JASYPT_HOME%\bin\jasypt-cli-bundle.jar;%JASYPT_HOME%\lib\commons-codec-1.1.jar;%JASYPT_HOME%\lib\commons-lang-2.1.jar;%JASYPT_HOME%\lib\icu4j-3.8.jar;%JASYPT_HOME%\lib\jasypt-1.5.jar .在　path下添加JASYPT_HOME\bin 加密公式：明文(可以是要加密的密码) + 密钥 =Jasypt默认算法= 密文@ECHO OFF %JASYPT_HOME%\bin\encrypt.bat input=E8iptsi855 password=PTSPASSWORD verbose=false .\passwd.txt 生成的密文wASjSlTjsgYFLyVswElJ4S7yjOcGnABF 解密: $ ./decrypt.sh input=k1AwOd5XuW4VfPQtEXEdVlMnaNn19hivMbn1G4JQgq/jArjtKqryXksYX4Hl6A0e password=MYPAS_WORD 具体可参见官方网站: Encrypting from the command line: Jasypt CLI Tools /cli.html 二个文件： perties datasource.driver=com.mysql.jdbc.Driver?? datasource.url=jdbc:mysql://localhost/reportsdb?? datasource.username=reportsUser?? datasource.password=ENC(G6N718UuyPE5bHyWKyuLQSm02auQPUtm)?? db.xml----- Xml代码property?name=vider_class?? jasypt.hibernate.connectionprovider.EncryptedPasswordDriverManagerConnectionProvider?? /property?? property?name=connection.passwordENC(G6N718UuyPE5bHyWKyuLQSm02auQPUtm)/property?? applicationContext.xml bean id=environmentVariablesConfiguration class=org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig ＜！――指定加密算法: PBEWithMD5AndDES ――＞ property name=algorithm value=PBEWithMD5AndDES / 　　　　　　　　＜！――指定密钥:PTSPASSWORD――＞ property name=password value=PTSPASSWORD / /bean ＜！――指定加密类: StandardPBEStringEncryptor ――＞ bean id=configurationEncryptor class=org.jasypt.encryption.pbe.StandardPBEStringEncryptor property name=config ref=environmentVariablesConfiguration / /bean ＜！――指定要已被加密的属性文件perties Jasypt集成了对spring的属性文件解密――＞ bean id=propertyConfigurer class=perties.EncryptablePropertyPlaceholderConfigurer constructor-arg r
