# How to find a element in elliptic curve ?(code added)

**Q=G*x**

**Q_2=G_2*y**

**G_2 = Q[n]=G[t]**

**Q=Q2**

**Q, G, G_2** are points on elliptic curve

**x, y** are big integers

**Q,Q_2, G, G_2, y** are known

*How to find x ?*

P.s. help me please. I'm very need help.

CODE:

p = 2 * * 256 - 2 * * 32 - 2 * * 9 - 2^8 - 2^7 - 2^6 - 2^4 - 1

a = 0x0000000000000000000000000000000000000000000000000000000000000000

b = 0x0000000000000000000000000000000000000000000000000000000000000007

F = GF(p) eccurve = EllipticCurve(F,[a, b]) curve = eccurve ord = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141

Gx = 0x79BE667EF9DCBBAC55A06295CE870B07029BFCDB2DCE28D959F2815B16F81798

Gy = 0x483ADA7726A3C4655DA4FBFC0E1108A8FD17B448A68554199C47D08FFB10D4B8

G = curve(Gx,Gy,1)

# This is a setion with data about Q !!! We are not calculating Q and we need find x and calculate Qz=x*G=Q. We are know Q,G but don't know x !!!

Q = curve(0x8b05b0603abd75b0c57489e451f811e1afe54a8715045cdf4888333f3ebc6e8b,0x1d10f88145db40fb889e2ddce81bda7c27f5b615acd6179dbb30f4fe7f40fb39)

print(Q)

R = Zmod(ord)

#### end of section

# this section calculated G2,y and Q = G2*y

x0 = R(0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF) y = 1/x0

G2 = ZZ( y ) *Q

Q2 = ZZ(x0) * G2

# End of section

# This section after x was find. Find x and paste to this code:

# x = ....

# Qresult=ZZ (x) * G

# print("Q==Qresult'", Q == Qresult)

## end of section

print("Q==Q2'", Q2 == Q)

print("Q",Q)

print("Q2",Q2)

print("y",y)

print("G",G)

print("G2",G2)

Could you please provide the code to construct

`Q, G, G_2, y`

?I will provide code for construct Q, G, G_2, y shortly. Thank you for your answer Tmonteil !!!Tmonteil I hope for your future help. Br !

HELP ME PLLEEEEASE FIND X ???? PLEEEASSSEE

HELP ME PLEASE ???

Please format sage / python code as code. For this, just indent all the code in some editor with 4 spaces or copy+paste it here, mark it, and while having it marked hit that button with the

`101`

and`010`

on it. As it is, the question is not readable. It would be also a good idea to describe the objects you have first, then the "needed $x$" with given properties. Could you please edit the question to have a readable text?
