Module description
Quoted from the NIST CMVP entry for this certificate.
The F-Secure Cryptographic Library for Windows (the Module) is a software module, implemented as a 32-bit Windows 'NT/2000/XP/98/ME' compatible DLL (FSCLM.DLL). The Module provides an assortment of cryptographic services to any client process that attaches an instance of the Module DLL. The Module is designed and implemented to meet the level 1 requirements of FIPS publication 140-2 when running on appropriate hardware under Windows 98, ME or XP operating system.
