checking checksums on binaries and checking for rootkits

[Brent Bailey]

hello,
im using FBSD 4.9 ... IS there a way to check the checksum on binairies
like "ls , ps" etc..  to check for rootkits ?

On Solaris you can run md5 on a binary and compare it against a utility on
SUNS website that will cehck the finger print to see whether the binary is
part of a rootkit or the original binary.  Does Freebsd have a tool like
this ?
