Database Backup file encryption

1. tar + openssl file encryption:

There is a folder named test in the current directory:

1. Use tar to encrypt the file:

# Tar-zcvf-pma | openssl des3-Salt-K password | dd of = test. des3

After the installation is complete, a package file named test. des3 is generated. Replace the password with your password.

2. decompress the encrypted file using tar:

# Dd if = test. des3 | openssl des3-D-K password | tar zxf-

Note: The command ends with "-", which releases all files. Here,-k password can be left blank. After the command is executed, you will be prompted to enter the password, and the-k parameter will be added to automatically verify the password in the program.
