| Use of weak or not validated cryptographic algorithms undermines the purposes of utilizing encryption and digital signatures to protect data. Weak algorithms can be easily broken and not validated cryptographic modules may not implement algorithms correctly. Unapproved cryptographic modules or algorithms should not be relied on for authentication, confidentiality or integrity. Weak cryptography could allow an attacker to gain access to and modify data stored in the database as well as the administration settings of the DBMS.
Applications, including DBMSs, utilizing cryptography are required to use approved NIST FIPS 140-2 or 140-3 validated cryptographic modules that meet the requirements of applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance.
NSA Type-X (where X=1, 2, 3, 4) products are NSA-certified, hardware-based encryption modules.
The standard for validating cryptographic modules will transition to the NIST FIPS 140-3 publication.
FIPS 140-2 modules can remain active for up to 5 years after validation or until September 21, 2026, when the FIPS 140-2 validations will be moved to the historical list. Even on the historical list, CMVP supports the purchase and use of these modules for existing systems. While Federal Agencies decide when they move to FIPS 140-3 only modules, purchasers are reminded that for several years there may be a limited selection of FIPS 140-3 modules from which to choose. CMVP recommends purchasers consider all modules that appear on the Validated Modules Search Page:

When the EDB FIPS 140 certified cryptographic modules are configured properly, an EDB Postgres Advanced Server will fail to start if non-FIPS 140 ciphers are specified for the Postgres ssl_ciphers parameter. To test whether the FIPS 140 compliant configuration is working, temporarily set the "ssl_ciphers" parameter in the postgresql.conf file to 'RC4-SHA' and then attempt to restart the database service. Since "RC4-SHA" is not a FIPS 140 approved cipher, the database will fail to start. Using the Event Viewer in Windows, a "FATAL: could not set the cipher list (no valid ciphers available)" error will be found under "Event Viewer (Local) >> Windows Logs >> Application".
