I'm preparing a chrooted environment for some command. I'm using CentOS 6. To determine what libraries do I need in my enviroment, I'm using strace:

strace <command> | grep open > needed.files.log

In the resulting log I see following lines:

open("/usr/lib64/libfreeblpriv3.chk", O_RDONLY) = 5
open("/usr/lib64/libfreeblpriv3.so", O_RDONLY) = 5
open("/usr/lib64/libsoftokn3.chk", O_RDONLY) = 5
open("/usr/lib64/libsoftokn3.so", O_RDONLY) = 5

I'm curious what are these .chk files for? Do I need to copy them to my chrooted environment with the .so libraries? I didn't find any information about them with google, it only shows me information about DOS/Windows chkdsk.

Checksum files required for the NSS softoken to operate in FIPS 140 mode - https://www-archive.mozilla.org/projects/security/pki/nss/tech-notes/tn6

If yes, than you shall need those.
