Disabling FIPS Compliant Algorithms (2024)

FAQs

Disabling FIPS Compliant Algorithms? ›

In Security Settings, expand Local Policies, and then click Security Options. Under Policy in the right pane, double-click System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing, and then click Disabled.

If FIPS is enabled, Windows can only use FIPS-validated encryption and advises all applications to do so as well. Other encryption schemes are blocked, even if they are newer, faster, and more secure. Because of this, disabling the FIPS mode will not cause any security issues.

AES encryption is compliant with FIPS 140-2. It's a symmetric encryption algorithm that uses cryptographic key lengths of 128, 192, and 256 bits to encrypt and decrypt a module's sensitive information. AES algorithms are notoriously difficult to crack, with longer key lengths offering additional protection.

It just blocks access to newer cryptography schemes that haven't been FIPS-validated. That means it won't be able to use new encryption schemes or faster ways of using the same encryption schemes. In other words, it makes your computer slower, less functional, and arguably less secure.

There's multiple reasons, but one is that the . NET framework that most Microsoft applications are coded in supplies both FIPS and non-FIPS versions of the same cryptographic algorithms. The non-FIPS versions have been available much longer (and so are used more widely) and are usually much faster.

FIPS (Federal Information Processing Standards) are a set of standards that describe document processing, encryption algorithms and other information technology standards for use within non-military government agencies and by government contractors and vendors who work with the agencies.

Who needs to be FIPS compliant? The main organizations that are required to be FIPS 140-2 compliant are federal government organizations that either collect, store, share, transfer, or disseminate sensitive data, such as Personally Identifiable Information.

In Security Settings, expand Local Policies, and then click Security Options. Under Policy in the right pane, double-click System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing, and then click Disabled.

Windows has a hidden setting that will enable only government-certified "FIPS-compliant" encryption. It may sound like a way to boost your PC's security, but it isn't. You shouldn't enable this setting unless you work in government or need to test how software will behave on government PCs.

Encryption modules for information technology and computer security programs that are running in FIPS mode will perform Federal Information Processing Standards-compliant functions such as key generation, encryption, and decryption.

How do I get out of FIPS mode? ›

As of October 2020, FIPS 140-2 and FIPS 140-3 are both accepted as current and active. FIPS 140-3 was approved on March 22, 2019 as the successor to FIPS 140-2 and became effective on September 22, 2019. FIPS 140-3 testing began on September 22, 2020, and a small number of validation certificates have been issued.

The Federal Information Processing Standard (FIPS) Publication 140 is a U.S. government standard that defines the minimum-security requirements for cryptographic modules in IT products. This topic introduces FIPS 140 validation for the Windows cryptographic modules.
