What is a FIPS 140-2 validated algorithm?

FIPS 140-2 stands for "Federal Information Processing Standards Publication 140-2." It is a standard for cryptographic modules that has been developed by the National Institute of Standards and Technology (NIST) to provide a set of requirements for the design, implementation, and operation of cryptographic modules.

A FIPS 140-2 validated algorithm is an encryption algorithm that has been evaluated and approved by NIST for use in cryptographic modules. In order to be approved, an algorithm must meet a set of technical requirements and must be tested by an independent laboratory to ensure that it is secure and reliable.

FIPS 140-2 validated algorithms are used in a wide range of applications, including secure communication, data protection, and authentication. They are often used in government and military applications, as well as in financial and healthcare industries.

FIPS 140-2 validation is an important consideration when selecting an encryption algorithm, because it provides assurance that the algorithm has been thoroughly tested and is considered secure by a reputable independent organization.
