if (computed == expected) { return true; } return false; }
private native boolean verifyPin(String pin, int timeInt); The checkPin method actually calls this after the sum check: apk time graveyard pin
Given the write-up context, I’ll conclude with: if (computed == expected) { return true; }
Example: Try to find T such that X as a 6-digit string (pad with leading zeros) has digit sum 24. We can brute over possible T (0..2359) and compute X, then pad to 6 digits, sum digits. } return false
for T in range(2400): # HHmm if T % 100 >= 60: continue # skip invalid minutes X = T ^ 0xCA7 s = f"{X:06d}" if sum(map(int, s)) == 24: print(f"{T:04d} -> {s}") Run yields:
We solve for integer X = int(pin):
