		Hi,
What kind of launch options / mask would I need to use with to use with hashcat if I wanted to crack a md5 hash that was just a floating point value from 0 - 1 to 16 decimal places like these examples:
0.9643639281918222
0.4074828438810318
I appreciate any help,
Thanks.

		just a note:
keyspace is: number_of_chars_in_charset ^ password_length (where ^ means "to the power of")
[0-9] = 10 digits to the power of (length) 16 (position 1 and 2 are fixed, you can check for 0.0000000000000000 and 1.0000000000000000 separately): 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 = 10,000,000,000,000,000
( this assumes all candidates are exactly of length 2 + 16 = 18)
quite a big number, isn't it?
feasible ? not really

		It's MD5 so with a decent rig you could get at least 20-40 G/s and cover the keyspace in 3-5 days.  Am I wrong?

~2 days on my old GTX Titan.
I'd say it's quite feasible.

		Is there an option to save all hashes to a file? -o only seems to work for the target.

		No, nor would you want to.
