Windows PowerShell provides access to a cryptographically secure pseudorandom number generator via the Get-SecureRandom cmdlet. [ 37 ] Cygwin on Windows provides implementations of both /dev/random and /dev/urandom , which can be used in scripts and programs.
PowerShell remoting: Using WS-Management, PowerShell 2.0 allows scripts and cmdlets to be invoked on a remote machine or a large set of remote machines. Background jobs : Also called a PSJob , it allows a command sequence (script) or pipeline to be invoked asynchronously.
After compromising a system, attackers often attempt to extract any stored credentials for further lateral movement through the network. A prime target is the LSASS process, which stores NTLM and Kerberos credentials.
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.
Hardware-based encryption is the use of computer hardware to assist software, or sometimes replace software, in the process of data encryption. Typically, this is implemented as part of the processor 's instruction set.
The data produced in the previous step is hashed with a cryptographic hash function such as SHA-1 or SHA-2. If desired, the hash function output can be truncated to provide a shorter, more convenient fingerprint. This process produces a short fingerprint which can be used to authenticate a much larger public key.
Function scrypt Inputs: This algorithm includes the following parameters: Passphrase: Bytes string of characters to be hashed Salt: Bytes string of random characters that modifies the hash to protect against Rainbow table attacks CostFactor (N): Integer CPU/memory cost parameter – Must be a power of 2 (e.g. 1024) BlockSizeFactor (r): Integer ...
BLAKE is a cryptographic hash function based on Daniel J. Bernstein's ChaCha stream cipher, but a permuted copy of the input block, XORed with round constants, is added before each ChaCha round. Like SHA-2, there are two variants differing in the word size. ChaCha operates on a 4×4 array of words.
