I use cfv myself to create checksum files. Note that using CRC
checksum is plenty if you are just worried about random corruption
caused by hardware errors (i.e., memory bitflips, hard drive hiccups).
Using a cryptographic checksum ala tripwire is useful if you are
worried about malicious attackers trying to modify files without your
noticing. Cryptographic checksums do take more CPU time, though.
