This gave an idea: I added an example hash (using first test vector) to
--list=format-details. Here's two ways to use it:
1. Give an example hash of mysql-sha1:
$ ./john --list=format-all-details --format=mysql-sha1
Format label mysql-sha1
Max. password length in bytes 32
Min. keys per crypt 8
Max. keys per crypt 8
Flags
Case sensitive yes
Supports 8-bit characters yes
Converts 8859-1 to UTF-16/UCS-2 no
Honours --encoding=NAME no
False positives possible no
Uses a bitslice implementation no
The split() method unifies case yes
A $dynamic$ format no
Number of test cases for --test 13
Algorithm name SHA1 128/128 AVX 8x
Format name MySQL 4.1+
Benchmark comment
Benchmark length -1
Binary size 20
Salt size 0
Example ciphertext
*5AD8F88516BD021DD43F171E2C785C69F8E54ADB
2. Check what format(s) has a "$7$" tag (this usually won't work for
formats that does not have a native tag, eg. NT):
$ ./john --list=format-details | grep -F '$7$' | awk '{print $1}'
scrypt
This is committed to bleeding-jumbo.
