Module description
Quoted from the NIST CMVP entry for this certificate.
KSECDD.SYS runs as a kernel mode export driver, and provides cryptographic services, through their documented interfaces, to Windows Vista kernel components. It supports several cryptographic algorithms accessible via a FIPS function table request irp (I/O request packet).
Approved algorithms (7)
Other algorithms
DES; Diffie-Hellman (key agreement; key establishment methodology provides between 112 and 150 bits of encryption strength; non-compliant less than 112 bits of encryption strength); EC Diffie-Hellman (key agreement; key establishment methodology provides 128 to 256 bits of encryption strength); MD2; MD4; MD5; RC2; RC4; HMAC MD5
Tested configurations
