Well, we already have MD5 (and SHA1) hashes built right into APR. HTTP also
specifies the Content-MD5 header for on-the-wire checksums.

At the moment, MD5 seems a reasonable way to do checksums, from the
standpoint of the various components. Being 128 bits in length, it is also
more resistent to false negatives than a 32 bit (or smaller!) CRC value.
