When a file is deleted, the list of disk clusters occupied by the file is erased, marking those sectors available for use by other files created or modified thereafter. TestDisk can recover deleted files especially if the file was not fragmented and the clusters have not been reused. There are two file recovery mechanisms in the TestDisk ...
The proposal from the GnuPG developers, which is called LibrePGP, was not taken up by the OpenPGP Working Group and future versions of GnuPG will not support the current version of OpenPGP. [6] GnuPG is part of the GNU Project and received major funding from the German government in 1999. [7]
Hard disk reader. A bad sector in computing is a disk sector on a disk storage unit that is unreadable. Upon taking damage, all information stored on that sector is lost. When a bad sector is found and marked, the operating system like Windows or Linux will skip it in the future. Bad sectors are a threat to information security in the sense of ...
Internal hard drive defect management is a system present in hard drives for handling of bad sectors.The systems are generally proprietary and vary from manufacturer to manufacturer, but typically consist of a "P" (for "permanent" or "primary") list of bad sectors detected in the manufacturing stage and a "G" (for "growth") list of bad sectors that crop up after manufacturing.

The problem in the running code was discovered in 1995 by Ian Goldberg and David Wagner, [4] who had to reverse engineer the object code because Netscape refused to reveal the details of its random number generation (security through obscurity). That RNG was fixed in later releases (version 2 and higher) by more robust (i.e., more random and so ...
In cryptography, the OpenPGP card [1] is an ISO/IEC 7816-4, -8 compatible smart card [2] that is integrated with many OpenPGP functions. Using this smart card, various cryptographic tasks (encryption, decryption, digital signing/verification, authentication etc.) can be performed.
The problem of correctly identifying a public key as belonging to a particular user is not unique to PGP. All public key/private key cryptosystems have the same problem, even if in slightly different guises, and no fully satisfactory solution is known.
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.
