Transparent Data Encryption (often abbreviated to TDE) is a technology employed by Microsoft, IBM and Oracle to encrypt database files. TDE offers encryption at file level. TDE enables the encryption of data at rest, encrypting databases both on the hard drive and consequently on backup media.
www.microsoft.com /en-us /research /project /microsoft-seal Simple Encrypted Arithmetic Library or SEAL is a free and open-source cross platform software library developed by Microsoft Research that implements various forms of homomorphic encryption .
BitLocker originated as a part of Microsoft's Next-Generation Secure Computing Base architecture in 2004 as a feature tentatively codenamed "Cornerstone" [4] [5] and was designed to protect information on devices, particularly if a device was lost or stolen.
Transparent data encryption (often abbreviated as TDE) is used to encrypt an entire database, [2] which therefore involves encrypting "data at rest". [4] Data at rest can generally be defined as "inactive" data that is not currently being edited or pushed across a network. [5]
The original creation of Gpg4win was initiated and funded by Germany's Federal Office for Information Security (BSI) in 2005, [2] [3] resulting in the release of Gpg4win 1.0.0 on 6 April 2006; [4] however Gpg4win and all included tools are free and open source software, and it is typically the non-proprietary option for privacy recommended [5] [6] to Windows users.
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
Data Protection Application Programming Interface (DPAPI) is a simple cryptographic application programming interface available as a built-in component in Windows 2000 and later versions of Microsoft Windows operating systems. In theory, the Data Protection API can enable symmetric encryption of any kind of data; in practice, its primary use in ...
However, a separate plugin provides Twofish as an encryption algorithm in KeePass 2.x. In KeePass 1.x (KDB database format), the integrity of the data is checked using a SHA-256 hash of the plaintext, whereas in KeePass 2.x (KDBX database format), the authenticity of the data is ensured using a HMAC-SHA-256 hash of the ciphertext (Encrypt-then ...
