# jasypt 敏感数据加密配置
# 详细用法可参考 https://github.com/ulisesbocchio/jasypt-spring-boot
jasypt:
  encryptor:
    password: 123456 # 秘钥，除了该项，下面都是默认值,该项建议设置 JVM 启动参数，如：-Djasypt.encryptor.password=123456
    algorithm: PBEWithMD5AndDES # 加密算法
    key-obtention-iterations: 1000 # 迭代次数，值越大越复杂，相对越安全
    pool-size: 1

    property:
      prefix: ENC( # 默认前缀
      suffix: ) # 默认后缀
