db2电话号码加密脚本

加密规则描述

  1.  号码中包含“-”的，“-”之前的数字不做脱敏加密处理操作，“-”之后的数字进脱敏加密处理操作。最后在“-”后面添加
    “-”来标识为脱敏加密后的电话号码；
  2.  移动电话（即号码中不包含“-”的），前三位不做脱敏加密处理操作，后面数字进行脱敏加密处理，最后采用3位,4位,4位的方式加上“-”隔开（如111-2222-3333）,
    来标识为脱敏加密后的电话号码；
  3.  将脱敏加密处理后的数据存储到数据库中，在必要的时候可以通过可逆解密，将脱敏后的电话号码解密转换成为原始电话号码。
  4.  将电话号码数字按照一定规则进行加密处理：
  5.  从理赔编码中选取倒数第二位数字判断奇偶性，使用对应的方法打乱需要进行加密的电话号码数字；

a) 如果需要加密的数字是7位，且理赔编码倒数第二位数字为奇数，按照第6,1,2,3,7,5,4的顺序取电话号码值进行重新组合；
b) 如果需要加密的数字是7位，且理赔编码倒数第二位数字为偶数，按照第4,5,7,3,2,1,6的顺序取电话号码值进行重新组合；
c) 如果需要加密的数字是8位，且理赔编码倒数第二位数字为奇数，按照第6,1,2,8,3,7,5,4的顺序取电话号码值进行重新组合；
d) 如果需要加密的数字是8位，且理赔编码倒数第二位数字为偶数，按照第4,5,7,3,8,2,1,6的顺序取电话号码值进行重新组合；

  1.  从理赔编码中选取后八位作为系数，与打乱顺序后电话号码数字依次对应求和取个位数作为加密后的数字。
