I wouldn't have to run the test to see the format name and algorithm name:
$ ./john --list=format-details |grep -E '\s(MySQL|NT MD4|Raw
SHA-1)$'|cut -f 1,6,7
mysql-fast 32/32 (label mysql-fast) MySQL
mysql 32/32 (label mysql) MySQL
nt 128/128 SSE2 + 32/32 NT MD4
nt2 128/128 SSE2 intrinsics 12x NT MD4
raw-sha1 128/128 SSE2 intrinsics 8x Raw SHA-1
raw-sha1-ng 128/128 SSE2 intrinsics 4x Raw SHA-1
BTW, --list=format-details lists the formats in the sequence they are
registered (same as --list=formats).
And for those who want to adjust the format names, here are the src files:
$ grep -E '"(MySQL|NT MD4|Raw SHA-1)"' *.c
MYSQL_fast_fmt_plug.c:#define FORMAT_NAME "MySQL"
MYSQL_fmt_plug.c:#define FORMAT_NAME "MySQL"
NT_fmt_plug.c:#define FORMAT_NAME "NT MD4"
nt2_fmt_plug.c:#define FORMAT_NAME "NT MD4"
opencl_nt_fmt.c:#define FORMAT_NAME "NT MD4"
rawSHA1_fmt_plug.c:#define FORMAT_NAME "Raw SHA-1"
rawSHA1_ng_fmt.c: .format_name = "Raw SHA-1",
Actually, I liked the idea to identify different format labels that
crack the same hash, together with seeing possible differences in
supported password length (in bytes):
$ ./john --list=format-details |grep -E '\s(MySQL|NT MD4|Raw
SHA-1)$'|cut -f 1,2
mysql-fast 32
mysql 32
nt 27
nt2 27
raw-sha1 55
raw-sha1-ng 15
Too bad that relbench needs distinct names to match benchmarks of
different output files.
