I don't know if the usage is the same in German, but in (USA) English
Computer Science, "crc32" most often refers specifically to the
algorithm implemented for Ethernet checksumming (which, with slight
variants is the same used in zlib, u-boot, and many others.)
CRC32 is not the only 32-bit CRC, but it is one of the most popular,
and was chosen for certain desirable properties.
(Wolfgang, I am sure you know all this, I am mostly clarifying for the
original poster.)
Lots of good info here:

Happy hacking!
