Jasypt代表Java简化加密，它提供纯文本，数字和二进制文件的基本加密以保护机密数据，它是完全线程安全的，并且在多处理器中也提供高性能。
Jasypt提供了更简单的加密和解密文本的方法，并且不需要任何深入的加密知识即可开始使用它，简单地，输入要加密的纯文本，Jasypt将完成其余的计算并为您这种加密是单向加密，它还提供了两种加密机制。
在实施双向加密时，除了提供纯文本之外，您还需要提供秘密文本，并且该秘密文本可用于解密加密的文本。
默认情况下，Jasypt使用PBEWithMD5AndDES加密算法，但它也提供选择其他更强加密选项的选项，例如PBEWithMD5AndTripleDES
spring: application: name: argus version: 2.0 data: elasticsearch: #ElasticsearchProperties cluster-name: idss-es #默认即为elasticsearch datasource: url: jdbc:mysql://x.x.x.x:3306/test?autoReconnect=true&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true driver-class-name: com.mysql.jdbc.Driver username: ENC(vpIBjT3RT8mf6pBjiKJuqA==) root password: ENC(xxxxxxxxxxxxx==) # User, Password encryptor salt jasypt: encryptor: password: EbfYkitulv73I2p0mXI50JMXoaxZTKJ7 下面免费的Jasypt在线加密和解密工具提供了一种方法以及两种（简单）加密和解密选项，还提供了比较纯文本和Jasypt加密密码的选项。
