Multiline Equations You can present equations with several lines, using the array statement. One of the greatest motivating forces for Donald Knuth when he began developing the original TeX system was to create something that allowed simple construction of mathematical formulae, while looking professional when printed. The fact that he succeeded was most probably why TeX (and later on, LaTeX) became so popular within the scientific community. Typesetting mathematics is one of LaTeX's greatest strengths. It is also a large topic due to the existence of so much mathematical notation. In this video Tahir Yaqub explains how to write math equations in Latex. Latex is a document preparation system.

How do I, in extreme specificity, convert a given private bitcoin key into a public bitcoin key Talk to me like I'm 5 and I have to do this step by step or the evil witch will cook me alive in her oven. Others have asked how to get private to public, I haven't seen a really specific answer, just more general direction, but no answers explain all the variables.

I understand this is rather complex and if a given individual thinks its too much work to answer, I totally respect that. Note: I do not care for the Bitcoin Address, just interested in Privatekey to Publickey and the specifics of how. Some of these variables are supposedly "random" which appears to be false as every generator that you can put a private key into seems to always spit out the same public key Thanks for any help on this.

I've been trying to research and understand this for days, but it seems sometimes I don't understand the terms and or notations, but I think I've gotten past that and now am just missing parts of the equation. All I want to know is how to go from that private key to the public key.

Supposedly it is a simple equation that doesn't involve bit shifting or xor etc. It may include "point multiplication" which I don't see how you can multiply a point defined as having both an x and a y. No one seems to understand the intricacies of this. Do you guys suggest I actually offer some fraction of a bitcoin to whoever explains it clearly? The full public key is 0x04, followed by 32 bytes of the x-coordinate, followed by 32 bytes of the y-coordinate.

The compressed public key is 0x02 or 0x03 depending on whether the y-coordinate is an even or odd number, followed by 32 bytes of the x-coordinate. Some older texts used to refer to scalar point multiplication, as exponentiation, that is why sometimes the private key is referred to the private exponent. Meaning that the NSA could or could not have put a mathematical backdoor in the curve parameters.

Here's a self-contained Python script that does the conversion. You can check its work by comparing to entering your private key as the "Secret Exponent" at Brainwallet. I took the script from this Bitcointalk thread and stripped out unnecessary stuff like the code to use the public key to sign a message and verify that signature. Converting the Python to instructions for a human is left as an exercise to the reader although I'd argue that in a scenario like this Python code, with appropriate documentation, is just fine as instructions to a human.

Note that it's entirely possible to compute this with pen and paper, but it could take a while, and you're likely to make a mistake, due to having to deal with such enormous numbers. I don't think a non-genius 5 year old could actually do it sorry, the evil witch wins this round , but I think an average adult with enough patience could learn the math needed in nearly no time with the Python script as a..

Actually calculating even one public key without the aid of electronic computing devices could take a very long time, however at a guess: years. The public key is a point x, y on the secpk1 curve which can be computed by multiplying the base point G with the secret key sk. Here is a self-contained concise python function, which does this:. Note that this implementation aims for clarity.

It is not efficient at all and probably also not safe against side channel timing attacks. An attacker could use the execution time of a call to this function to derive information about the secret key. An elliptic curve "EC" is a function in which the square of the y coordinate is equal to a third degree polynomial of the x coordinate.

This is how I understand ECC, and it may be inaccurate. I would very much appreciate any corrections or questions so that I can hone this description. Given the other answers here already, I thought this one might help a lot of people. The description of point multiplication on Wikipedia was helpful in understanding where the l values are coming from. Sign up to join this community.

Nope, that was a programming question and it didn't show where "k" came from etc.

The actual value will be: 0xfea5d6bc1c14de5beb42a8d13f3abbcd08affcc2a5e6bb8d63, 0x4cbe83d40b0f73afcccf6b1f4b08d3c07b27fb8d8cad1 The public key will then be in one of two formats: full, this is a 65 byte number, starting with a byte 0x04 compressed, this is a shorter form, 33 bytes, starting with either 0x02 or 0x Then some more notes on your question: Some older texts used to refer to scalar point multiplication, as exponentiation, that is why sometimes the private key is referred to the private exponent.

It's no longer just ecdsa. Please post a bitcoin address! Edit: found it on your linked web site � Eric S Aug 6 '14 at One thing: you may want to explicitly indicate that the "NSA-proof" parameters of the curve specifically refer to G in your explanation, so that number is explained in essence, G is just a large prime number that has certain properties wrt elliptical curves. And, whether this curve is NSA-proof is point of discussion, see the link i added. Regarding G, I'm now curious about what exactly this is, so I asked a follow-up question here: bitcoin.

So whats the actual public key for ? Show 1 more comment. Parse "adaa3cda4fbfc0ea8fd17bac47d08ffb10d4b8", NumberStyles. HexNumber ; Console. ToString "X" , pubkeyPoint. X, this. Y - left. X - left. X - right. Curve, left. X, -left. Tim S. I think I may almost have it So, we multiply the "generator" by the "secret" and the "secret" is simply the private key.

What occurs to those numbers to equal the "curve" and then what happens to that to create "generator"? Then, how is pubkeypoint broken up to give you the x and y value? When you do new CurveFp p,a,b , the numbers are simply stored. You can think of a curve as a pairing of three numbers. Similarly, a Point is simply a pairing of a Curve and two numbers.

The result of this very complicated multiplication is a Point ; its X and Y, concatenated together, are the public key. May 2 '14 at Oh crud. If all the C code applies then perhaps it really is too complex for someone to explain it all to me. When reading it it looked like the additional calculations were for the bitcoin address or the signature rather than just the public key as I have no need or care for the signature or address right now since I think it will only serve to further confuse me.

I see you reference those things signature and address. I'm only looking to find how to convert the Private key to Public key and what variables are needed etc. No address, no signature, nothing more.

Yep, I'm afraid the C really is just the private to public, no signing or address involved. If you're looking to understand it, without necessarily being able to compute it practically, you can break it down into its mathematical components and research them: elliptic curves, working modulo a number p , InverseMod , etc.

Reading code is good for, "I don't care why or how it works, just make it work". That sort of research would be better for understanding the algorithms involved. I understand what you mean. My concern is that I can read code and get the idea of whats going on, but I don't always understand the full specifics or follow it right.

I have been researching it but even those explanations I don't entirely follow as they seem to switch variables.
