Bila guna bash script, dan perlu sorokkan password, boleh guna encrypt base64, kemudian decrypt balik
#!/bin/sh
username='my_username'
password='my_password'
username_encoded=$(echo -n "$username" | openssl enc -base64)
password_encoded=$(echo -n "$password" | openssl enc -base64)
username_decoded=$(echo "$username_encoded" | openssl enc -d -base64)
password_decoded=$(echo "$password_encoded" | openssl enc -d -base64)
echo "username: $username"
echo "username_encoded: $username_encoded"
echo "username_decoded: $username_decoded"
echo "password: $password"
echo "password_encoded: $password_encoded"
echo "password_decoded: $password_decoded"
Output:
username: my_username
username_encoded: bXlfdXNlcm5hbWU=
username_decoded: my_username
password: my_password
password_encoded: bXlfcGFzc3dvcmQ=
password_decoded: my_password
Bila encode, ada hantar newline. Bila decode, tak new line, tak payah guna
-n pada echo.
Contoh bila nak guna. Setkan awal-awal, hasilnya, masukkan dalam script untuk di decode kan semula.
mygpis@mygpis-db:~$ echo -n "mysecpassword" | openssl enc -base64
TXlHUElTMTIz
mygpis@mygpis-db:~$ vi task.sh
#!/bin/bash
DBHOST='localhost'
DBUSRN='root'
#DBPASS='mysecpassword'#commentkan
DBNAME='mygpis'
DBPASS=$(echo "TXlHUElTMTIz" | openssl enc -d -base64)
