```python
# Пример скрипта для алгоритма кенгуру Полларда для поиска закрытого ключа по открытому ключу
# Открытый ключ
public_key = "03633cbe3ec02b9401c5effa144c5b4d22f87940259634858fc7e59b1c09937852"
# Параметры кривой (можете изменить на свои значения)
p = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2F
g = 2
# Функция для вычисления значения открытого ключа
def calculate_public_key(x):
return pow(g, x, p)
# Начальные значения для "кенгуру" и "черепахи"
x1 = 1
x2 = 2
# Вычисление значений функции для "кенгуру" и "черепахи"
y1 = calculate_public_key(x1)
y2 = calculate_public_key(x2)
# Поиск коллизии
while y1 != y2:
# Шаг "кенгуру"
x1 += 1
y1 = calculate_public_key(x1)
# Шаг "черепахи"
x2 += 2
y2 = calculate_public_key(x2)
# Найдена коллизия, вычисление закрытого ключа
private_key = x2 - x1
print("Private key:", private_key)
```
Теперь функция `calculate_public_key` определена перед ее использованием, так что скрипт должен работать правильно. Попробуйте запустить его снова.
