More and more cloud services enter our life. Such as Cloud file store service Dropbox. We can not only rely on the Safety of the service provider.
Two way to encrypt your content or files:
1. Encrypt by password in VIM
Just enter:
:set key=<password>
when you editing the file, then the file will be encrypted.
When opening the encrypted file, you will be asked to input the password.
If you want to convert a encrypted file to be a plain file, you should set the <password> to be empty.
2. Encrypt files by mcrypt in UBUNTU:
Install mcrypt:
sudo apt-get install mycrypt
Encrypt a file with password:
mcrypt -a blowfish test.txt
You will get a file named
test.txt.nc
Decrypt the .nc file
mycrypt -d test.txt.nc
