Data recovery from encrypted storages
The need for information security in a world that almost fully rests on digital technologies is undoubted. Protection of sensitive data has become a matter of a great concern in different life spheres: client and partner information, intellectual property items, business plans or accountancy and simply any personal data, like health information. Data storage system encryption is presently available for all prone to keep their data safe and secure.
Volume encryption works in a way that even if the storage falls into wrong hands any unauthorized access to storage data will be denied. This can be performed by encryption software or hardware and is today available for different storage media from removable flash drives to NAS storages.
Volume encryption secures all user data on the storage with a special encryption key paired with the user password for the system. At the point of booting, the system needs to address the encryption key kept in the disk memory to start. Another layer of security is offered by modern enhanced encryption algorithms when a secret key is used for the encryption key. If all the keys fall together, access to the storage is allowed.
Yes, disk encryption protects and secures the data from thieves and malicious software, but it won't be able to protect it from failures or damages within the system.As the encryption key is stored somewhere in the disk space, in a manner and place that depends on cipher algorithm, it's obvious that it can be lost just like any other data on your storage. Loss of encryption key leads to the inability to access the data inside the system. It remains encrypted and the key to decrypt it is lost.
Today's common belief is that the encrypted data goes for good together with the encryption key. SysDev Laboratories developed a tool for recovery of an encryption key. UFS Explorer Professional Recovery recognizes a variety of encryption algorithms including LUKS, AES (Rijndael), Serpent, Twofish, Blowfish etc. and supports different chaining modes such as popular CBC and more complicated XTS. The software offers recovery of encrypted data from a variety of storage systems including NAS.
