100 randomly generated characters (a-z, A-Z, 0-9) would be 595 bits of entropy. You will not be brute forcing it. Although 100 characters is pretty excessive, since a Bitcoin address only has 160 bits of entropy.
Remember scales - there is a lot more entropy in 160 bits than there is in 100 bits.
I don't think you read my statement very carefully. The password has 595 bits of entropy, not 100.
Oh dear... I do that a lot. You're right.
