I tried a different grep and ended up with mostly the same list (sha0 is
just a false positive of course).
$ git grep -lE "ALGORITHM_NAME.*SHA[- ]?[235]"|grep -vE
"opencl|cuda"|xargs grep -L SIMD
7z_fmt_plug.c
clipperz_srp_fmt_plug.c
dragonfly3_fmt_plug.c
dragonfly4_fmt_plug.c
episerver_fmt_plug.c
keepass_fmt_plug.c
pdf_fmt_plug.c
rawSHA0_fmt_plug.c
The dragonfly formats are not very interesting. I guess the 7z format
would be appreciated but it's tricky with different length candidates in
a batch. I'm not sure about the others.
