## 1. gzexe 对文件进行加单加密,不安全,但是脚本可执行. ``` root@ubuntu01:~# vim hello.sh\ > #!/bin/bash echo "hello world! tuna" ``` 1. 加密 ``` gzexe hello.sh hello.sh: -5.4% ``` 2. 再次查看,被打乱了 ``` root@ubuntu01:~# cat hello.sh #!/bin/bash skip=44 tab=' ' nl=' ' IFS=" $tab$nl" umask=`umask` umask 77 gztmpdir= trap 'res=$? test -n "$gztmpdir" && rm -fr "$gztmpdir" (exit $res); exit $res ' 0 1 2 3 5 10 13 15 if type mktemp >/dev/null 2>&1; then ``` 3.解密 ``` root@ubuntu01:~# gzexe -d hello.sh root@ubuntu01:~# root@ubuntu01:~# root@ubuntu01:~# root@ubuntu01:~# root@ubuntu01:~# cat hello.sh #!/bin/bash echo "hello world! tuna" ```
