How do I unencrypt an encrypted EBS volume?
Resolution
- Create a snapshot of the encrypted root volume, or create an AMI of the instance with the encrypted volume.
- Open the Amazon EC2 console.
- Stop the instance with the encrypted root volume.
- In the Description tab, under Root device, choose the root volume, and then choose the EBS ID.
How is AES used to encrypt files?
One of my software (an R package) has to save on disk users sensitive information. I encrypt such information using AES encryption using a random key that is generated at the moment of installation (which is saved in the same directory where I store the user profile).
What happens when I swap my encryption key?
Any user access to the encrypted data after the recycling point of the current encryption key trigger your decrypt with current key and encrypt with new key. This will avoid the need to execute a huge encrypt/decrypt process for all the stored data at concurrently. Finally, what is the security requirement behind this request.
Do you need a key for symmetric encryption?
The symmetric encryption classes supplied by the .NET Framework require a key and a new initialization vector (IV) to encrypt and decrypt data. Whenever you create a new instance of one of the managed symmetric cryptographic classes using the parameterless constructor, a new key and IV are automatically created.
When do I need to change my encryption key?
If one of key or data were compromised, it might make sense to change the key and re-encrypt the data in case an attacker might get the other half of the puzzle somehow. However, this smells like “change your password every 30 days, Just In Case.) You mentioned one risk of decrypting and re-encrypting, namely a failure partway through the process.
