Encryption contributes to data security a lot. But, it also challenges data recovery. In this article, we will elaborately expose how encryption can make impacts on data recovery.
Nowadays, no matter businesses or individuals start to use encryption to protect valuable data and strengthen data privacy. Simply put, when data is encrypted, it is converted to a series of gibberish via a special algorithm. Only when you enter the correct decryption key, can such data restore to its original state, and thus we can read it. Moreover, encryption is not the same as password protection. It is exactly much more complex than a password. In a nutshell, encryption does play a great and effective role in data security.
Nevertheless, meanwhile, encryption also complicates the data recovery process. To be specific, to recover common files, such as a non-encrypted corrupt PST file, reliable and potent data recovery software can be up to this task. But, to retrieve the encrypted data, one more critical step demands in data recovery, namely the so-called decryption. Now, in the followings, we will tell you the impacts of encryption on data recovery in 3 respects.
More Chances for Data Losses
As we all know, data can get lost for many reasons, including hardware failures, software faults, and human errors, etc. But, in terms of encrypted data, there is one more particular data loss cause. It is losing encryption key, which is also pretty common. It is admittedly hard to manage keys. Lost or incorrect encryption key can result in inability for users to decrypt their data. Therefore, encryption leads to more chances for data losses.
When you lose your data due to missing encryption key, you must think of data recovery. However, you should accept that data recovery in this case is quite hard. Just imagine it. If data recovery was easy, why you encrypt your data? The reason why we encrypt data is preventing data from falling into wrong hands. But, if the encrypted data could be easily recovered, there is not any point to encrypt it. So, as a matter fact, decryption is really difficult and the chances for successful data recovery are considerably low and even impossible.
We can encrypt our data through software or directly from hardware, namely self-encrypting devices (SED). Such drives have a controller chip which can auto encrypt and decrypt the drive data. On such SEDs, there are no decryption means. That is to say, if a SED suffers physical damage, the internal data will disappear forever. It is meaningless to attempt data recovery.
