![]() ![]() By extracting such keys from the computer’s RAM you can bypass lengthy attacks and unlock encrypted volumes in an instant. ![]() The decryption keys are stored on a different physical server (so at least the data is protected against physical break-ins), but easily accessible when you’re pulling the data chunks.Ĭrypto containers such as BitLocker, TrueCrypt/VeraCrypt or PGP store their on-the-fly encryption keys in the computer’s volatile memory. iCloud backups produced by your iPhone, for example, are securely encrypted with industry-standard AES256 encryption. Data access: Instant, password can be extracted and used for decryptionĮxamples of such strategies are many.Password: Stored alongside with the data.However, the very fact that the key is accessible alongside with the data makes the decryption instant (if not always trivial). When using this strategy, the data is encrypted, meaning that accessing it without the key (by resetting or removing the password, for example) is not possible. Unsurprisingly, this strategy has a name of “Keys Under Doormats”. Such passwords can be removed easily with Advanced Office Password Recovery (Microsoft Office documents) or Advanced PDF Password Recovery (PDF files).Įver hidden the front-door key under a doormat “just in case”? Believe it or not, many passwords (as well as actual encryption keys) are stored alongside with the data they are designed to protect. Users can lock access to certain features in PDF files and Microsoft Office documents, disabling the ability to print or edit the whole document or some parts of the document. Instead, the key is generated when the user first enters their passcode after the device starts up or reboots. The actual data encryption key is not stored anywhere on the device. For these devices, the passcode (user input) is an important part of data protection. All passwords protecting certain features of a document without encrypting its content (such as the “password to edit” when you can already view, or “password to copy”, or “password to print”) also belong to this category.Ī good counter-example would be modern Android smartphones using File-Based Encryption, or all Apple iOS devices. For such devices, the device passcode merely locks access to the user interface by the time the system asks for the password, the data is already decrypted using hardware credentials and the password (please don’t laugh) ‘ default_password’. Data access: Instant, password can be bypassed, removed or resetĪ good example of such protection would be older Android smartphones using the legacy Full Disk Encryption without Secure Startup.The actual data is either not encrypted at all or is encrypted with some other credentials that do not depend on the password. In this scenario, the password is the lock. In this article, we’ll explain the differences between the many types of password protection. ![]() There are multiple types of password protection, all having their legitimate use cases. Why wasting time recovering passwords instead of just breaking in? Why can we crack some passwords but still have to recover the others? Not all types of protection are equal. ![]()
