DPAPI security relies upon the Windows operating system's ability to protect the master key and RSA private keys from compromise, which in most attack scenarios is most highly reliant on the security of the end user's credentials. A main encryption/decryption key is derived from user's password by PBKDF2 function. [2]
Windows Mobile 6.5, Windows RT and core editions of Windows 8.1 include device encryption, a feature-limited version of BitLocker that encrypts the whole system. [ 21 ] [ 22 ] [ 23 ] Logging in with a Microsoft account with administrative privileges automatically begins the encryption process.
Screenshot of the Syskey utility on the Windows 8.1 operating system requesting the user to enter a password.. The SAM Lock Tool, better known as Syskey (the name of its executable file), is a discontinued component of Windows NT that encrypts the Security Account Manager (SAM) database using a 128-bit RC4 encryption key.
At AOL, we make every effort to keep your personal information totally secure. SSL (Secure Sockets Layer) is an industry standard for encrypting private data sent over the Internet. It helps protect your account from hackers and insures the security of private data sent over the Internet, like credit cards and passwords.
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.
In Excel and Word 95 and prior editions a weak protection algorithm is used that converts a password to a 16-bit verifier and a 16-byte XOR obfuscation array [1] key. [4] 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]
While you'll need to contact your software vendor for specifics to your software, most browsers will allow you a temporary bypass by holding down the Shift key as you click web site links. Additionally, try using the following friendly URLs when accessing AOL Mail: "*.aol.com" "registration.aol.com" "webmail.aol.com"
In Windows 2000, XP or later, the user's RSA private key is encrypted using a hash of the user's NTLM password hash plus the user name – use of a salted hash makes it extremely difficult to reverse the process and recover the private key without knowing the user's passphrase. Also, again, setting Syskey to mode 2 or 3 (Syskey typed in during ...
