VeraCrypt. VeraCrypt is a free and open-source utility for on-the-fly encryption (OTFE). [ 5] The software can create a virtual encrypted disk that works just like a regular disk but within a file. It can also encrypt a partition [ 6] or (in Windows) the entire storage device with pre-boot authentication.
Trusted Platform Module ( TPM) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. The term can also refer to a chip conforming to the standard ISO/IEC 11889. Common uses are to verify platform integrity (to verify that the boot process starts ...
BitLocker is a logical volume encryption system. (A volume spans part of a hard disk drive, the whole drive or more than one drive.) When enabled, TPM and BitLocker can ensure the integrity of the trusted boot path (e.g. BIOS and boot sector), in order to prevent most offline physical attacks and boot sector malware.
An HSM in PCIe format. A hardware security module ( HSM) is a physical computing device that safeguards and manages secrets (most importantly digital keys ), performs encryption and decryption functions for digital signatures, strong authentication and other cryptographic functions. [ 1] These modules traditionally come in the form of a plug-in ...
Layering. Whole disk: Whether the whole physical disk or logical volume can be encrypted, including the partition tables and master boot record. Note that this does not imply that the encrypted disk can be used as the boot disk itself; refer to pre-boot authentication in the features comparison table.
Self-signed certificates have their own limited uses. They have full trust value when the issuer and the sole user are the same entity. For example, the Encrypting File System on Microsoft Windows issues a self-signed certificate on behalf of the encrypting user and uses it to transparently decrypt data on the fly.
The 140 series of Federal Information Processing Standards ( FIPS) are U.S. government computer security standards that specify requirements for cryptographic modules . As of October 2020, FIPS 140-2 and FIPS 140-3 are both accepted as current and active. [ 1] FIPS 140-3 was approved on March 22, 2019 as the successor to FIPS 140-2 and became ...
DeCSS. A fragment of the DeCSS code, which can be used by a computer to circumvent a DVD's copy protection. DeCSS is one of the first free computer programs capable of decrypting content on a commercially produced DVD video disc. Before the release of DeCSS, free and open source operating systems (such as BSD and Linux) could not play encrypted ...
