Cain and Abel (often abbreviated to Cain) was a password recovery tool for Microsoft Windows.It could recover many kinds of passwords using methods such as network packet sniffing, cracking various password hashes by using methods such as dictionary attacks, brute force and cryptanalysis attacks. [1]
The purpose of password cracking might be to help a user recover a forgotten password (due to the fact that installing an entirely new password would involve System Administration privileges), to gain unauthorized access to a system, or to act as a preventive measure whereby system administrators check for easily crackable passwords. On a file ...
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.
When password-guessing, this method is very fast when used to check all short passwords, but for longer passwords other methods such as the dictionary attack are used because a brute-force search takes too long. Longer passwords, passphrases and keys have more possible values, making them exponentially more difficult to crack than shorter ones ...
Passphrase strengthening: Whether key strengthening is used with plain text passwords to frustrate dictionary attacks, usually using PBKDF2 or Argon2. Hardware acceleration: Whether dedicated cryptographic accelerator expansion cards can be taken advantage of. Trusted Platform Module: Whether the implementation can use a TPM cryptoprocessor.
The added computational work makes password cracking much more difficult, and is known as key stretching. When the standard was written in the year 2000 the recommended minimum number of iterations was 1,000, but the parameter is intended to be increased over time as CPU speeds increase.
While these default settings make VeraCrypt slower at opening encrypted partitions, it also makes password-guessing attacks slower. [ 20 ] Additionally, since version 1.12, a new feature called "Personal Iterations Multiplier" (PIM) provides a parameter whose value is used to control the number of iterations used by the header key derivation ...
An MD5 hash of this passphrase can be cracked in 4 seconds using crackstation.net, indicating that the phrase is found in password cracking databases.) Using this guideline, to achieve the 80-bit strength recommended for high security (non-military) by NIST , a passphrase would need to be 58 characters long, assuming a composition that includes ...
