Summary:
The default algorithm used is MD5. However, MD5 is not supported with
fips and can cause a SIGSEGV. Set CRC32 instead which is a standard for
checksum computation and is not restricted by fips.
crc32 is also faster than md5.

Internally at IBM, we hit the following SIGSEGV

```
0x0000000000000000 in ?? ()
