What is SysKey Encryption?

Skykey is a Windows utility that allows the creation of an encryption key in the SAM database that has been stored in the Windows Registry. It is not configured in any of the Windows Operating Systems by default. It works on all previous versions of Windows like Windows XP, Vista, 7, 8.1, and Windows 10 computers. This can be optional if you create a startup password (syskey) that can ask you for a boot password. However, it is not required. But do you know how to remove startup passwords from your Windows?

Uses of Syskey Encryption?

Syskey is a Windows internal root encryption key used to encrypt other sensitive OS state data, such as user account password hashes. The SysKey utility is used to add an extra layer of protection by encrypting the syskey to use an external password. The keys are not mandatory but are always an excellent option to keep your data protected.

Bruteforcing the Syskey

While SYSKEY was not using the most robust encryption, attacking (brute-forcing or resetting) the user’s Windows login and password would not be possible without first decrypting the SAM database. As a result, an SYSKEY password would require the attacker to brute-force or reset SYSKEY protection before accessing the system’s Windows accounts. More importantly, an unknown SYSKEY password would prevent the user’s system from entirely booting. This fact was widely exploited by ransomware and commonly abused by “tech support” scammers who locked victims out of their computers via fake “tech support” calls.
