Mind numbing...
Im trying to find how many guesses this will take.

***
If the chance of one
character to match the
right value is 0.064241301929618127222340104036059
***

***
Then the chance for all 10 characters to match their corresponding character is ?A?
***

***
If the chance to match all 10 characters to their corresponding character is ?A? then it will take about ?B? guesses to get them each to match their corresponding vharacter at 100,000 guesses per second
***

What are ?A? and ?B?

If I understand your question correctly then you have approximately a 6% chance of guessing the first event correctly. To guess 2 events correctly in a row then you multiple the two probabilities together ie 6% * 6%. So to calculate 10 events you simply do $\displaystyle 0.06^{10}$.
To work out how many guesses each will take then you can do $\displaystyle \frac 1{0.06^{10}}$
$\displaystyle \frac{\frac 1{0.06^{10}}}{100000}$
