Thank you for answering me. If I know that I probably put 10 characters with a capital letter at the beginning and 2 number at the end without knowing what it was, I have a chance to find the password with a script?
1 capital letter == 26^1 == 26
2 digits == 10^2 == 100
7 mixed case == 52^7 == 1028071702528
26 * 100 * 1028071702528 == 2672986426572800
2672986426572800 passwords / 10 passwords per second == 8,470,364 years
