The use of random is not recommended for cryptographic or security purposes.

Warning The pseudo-random generators of this module should not be used for security purposes. For security or cryptographic uses, see the secrets module.

Reference: https://docs.python.org/3/library/random.html (Red Box warning)

If the project wants to use random for legacy reasons, it should atleast be mentioned that it is insecure. If this is mentioned elsewhere in the book, please close the issue.

Was getting this error in the pip install -r requirements.txt step

      src/_fastmath.c:36:11: fatal error: 'gmp.h' file not found
      # include <gmp.h>
                ^~~~~~~
      1 error generated.
      error: command '/usr/bin/clang' failed with exit code 1
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for pycrypto
  Running setup.py clean for pycrypto
Failed to build pycrypto
Installing collected packages: pycrypto
  Running setup.py install for pycrypto ... error
  error: subprocess-exited-with-error

Turns out I was able to prepend the install command like this, which then made it work:

env "CFLAGS=-I/usr/local/include -L/usr/local/lib" pip install -r requirements.txt

Здравствуйте, не знал куда написать, пишу сюда, по поводу выполнения упражнения 1 в главе 3, выдает ошибку PS C:\Users\banda> & C:/Users/banda/AppData/Local/Programs/ Python/Python39/python.exe c:/Users/banda/Desktop/PY3/main.py Возврат
(последний последний вызов):
Файл «c:\Users\banda\Desktop\PY3\main.py», строка 109, в
print(on_curve(Элемент поля(192, простое число), Элемент поля(105, простое число)))
Файл "c:\Users\banda\Desktop\PY3\main.py ", строка 108, в on_curve
return y 2 == x 3 + a*x +b
Ошибка типа: Неподдерживаемые типы операндов для *: «Элемент поля» и «Элемент поля».
Я вставил код, опубликованный на Github, ошибка сохраняется.
PS буду рад оказанной помощи

from ecc import FieldElement
prime = 223
a = FieldElement(0, prime)
b = FieldElement(7, prime)
def on_curve(x,y):
... return y 2 == x 3 + a*x + b
print(on_curve (FieldElement(192, простое), FieldElement(105, простое)))
True
print(on_curve(FieldElement(17, простое), FieldElement(56, простое)))
True
print(on_curve(FieldElement(200, простое), FieldElement( 119, штрих)))
Ложь
print(on_curve(FieldElement(1, штрих), FieldElement(193, штрих)))
True
print(on_curve(FieldElement(42, штрих), FieldElement(99, штрих)))
False
