When used in conjunction with a compatible Trusted Platform Module (TPM), BitLocker can validate the integrity of boot and system files before decrypting a protected volume; an unsuccessful validation will prohibit access to a protected system. [6] [7] BitLocker was briefly called Secure Startup before Windows Vista's release to manufacturing. [6]
In Windows 2000, the local administrator is the default Data Recovery Agent, capable of decrypting all files encrypted with EFS by any local user. EFS in Windows 2000 cannot function without a recovery agent, so there is always someone who can decrypt encrypted files of the users.
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 ...
The process of encrypting and decrypting messages involves keys. The two main types of keys in cryptographic systems are symmetric-key and public-key (also known as asymmetric-key). [9] [10] Many complex cryptographic algorithms often use simple modular arithmetic in their implementations. [11]
The Microsoft Windows platform specific Cryptographic Application Programming Interface (also known variously as CryptoAPI, Microsoft Cryptography API, MS-CAPI or simply CAPI) is an application programming interface included with Microsoft Windows operating systems that provides services to enable developers to secure Windows-based applications using cryptography.
Hacking software is now readily available to find a 16-byte key and decrypt the password-protected document. [5] Office 97, 2000, XP and 2003 use RC4 with 40 bits. [4] The implementation contains multiple vulnerabilities rendering it insecure. [5] In Office XP and 2003 an opportunity to use a custom protection algorithm was added. [4]
SSL (Secure Sockets Layer) is an industry standard for encrypting private data sent over the Internet to help protect your account and information. Learn what SSL is and how we use it to protect your account.
The file in the mountpoint provides the unencrypted view of the one in the source directory. Filenames are encrypted in the source directory. Files are encrypted using a volume key, which is stored either within or outside the encrypted source directory. [6] A password is used to decrypt this key.
