This list is not limited to hashes supported in the main JtR, but it is
incomplete in other ways.  Please feel free to add to it (once you
figure things out).

For all hash types supported by whatever version of JtR you're using,
you may find some sample hashes in test[] arrays in the *_fmt.c files.
In your case, you'd want to look at mssql_fmt.c and mssql05_fmt.c.  The
hash encodings given in there are 94 or 54 characters long, including
the leading "0x".

Yes, John definitely needs the salt.

I am not familiar with MS SQL hashes at all, but it might be something
like: "0x0100" hash type identifier and flags (6 chars), then the salt
(8 chars?), then your 40 hex char hash.  This gives 54, which matches
some of the test vectors in mssql05_fmt.c.

I hope this helps.
