How do you encrypt stored data?

1 Answer

1. Generate a public/private key pair for each user; and only ever decrypt the private key temporarily with the user’s password.
2. For each data item, randomly choose a (symmetric) key S and encrypt the data d with it.
3. Encrypt S with the the public key P+u of the user you want to grant access.

How is data encrypted at rest?

The encryption of data at rest should only include strong encryption methods such as AES or RSA. Encrypted data should remain encrypted when access controls such as usernames and password fail. Cryptography can be implemented on the database housing the data and on the physical storage where the databases are stored.

Should I encrypt form data?

The short answer is that the form data will be encrypted, but it won’t necessarily be safe. If the form data is posted to a page that begins “HTTPS,” the browser will attempt to establish an SSL connection with the server named in the form’s action URL; the connection will take place over port 443.

Which is the best encryption for mysqldump script?

Go with asymmetric encryption! You can use OpenSSL S/Mime which can handle large file encryption as well. If you encrypt your backups, make sure not simply write the unencrypted files to disk, encrypt them and delete the original files.

Is there a way to encrypt MySQL backups?

One of the methods you can use to encrypt the data is to use openssl: ? This will create a new, encrypted file, ‘backup_file.tar.gz.enc’ in the current directory. You can always decrypt it later by running: ? This method is very simple, but it has some drawbacks. The biggest one is the disk space requirements.

Is it bad to use password in mysqldump?

Using a password inside the script is a really bad idea as this can be seen in ps aux and read out by every system user. I would suggest you to look into mysqldump-secure. This is a shell script that does openssl encryption based on public-private key encryption and is a lot more performant than gpg.

Is it safe to encrypt database dumps?

Before you are going to encrypt your database dumps you have to choose a method which best suits security. You have one key or password which is used for encryption and also for decryption. If someone gets hands on this key/password on the server which does the backup your database dumps are considered compromised.
