QUESTION
I am trying to send a get request to an api and get a response. My code is working fine but there is a problem with body of response, I am getting numbers before and after body of the response. Here is my code:
...ANSWER
Answered 2021-Jun-29 at 18:19I am missing something but what?
You are not taking into account that these responses are using the chunked transfer encoding format (via the Transfer-Encoding: chunked header) to send the body data in chunks instead of a single byte stream, as you are expecting. See RFC 2616 Section 3.6.1 and RFC 7230 Section 4.1 for more details on the chunked format.
What are they?
The numbers you are referring to are chunk size indicators.
In the 1st response shown, there is a single chunk of data whose byte size is
4a0(0x4A0 hex, 1184 decimal), followed by a terminating chunk whose byte size is0.In the 2nd response shown, there is a single chunk of data whose byte size is
bcd(0xBCD hex, 3021 decimal), followed by a terminating chunk whose byte size is0.
The 0-length chunk ends the body data (there is no Content-Length or Connection: close header present to end the responses otherwise).
You won't be able to use a simple recv() loop to read chunked bodies. You have to detect the chunked header, and if present then read and parse each chunk individually. Read a chunk size, skip up to the following CRLF, read the specified number of bytes, skip up to the following CRLF. Repeat until a 0-length chunk is reached. Then read a set of trailing HTTP headers that may follow the chunks, overwriting any headers that you read before the body.
See the pseudo code I present in this answer and this answer.

I'm trying to understand how i can create a pair of bitcoin private key and public key and import them in electrum wallet
1 try with : https://github.com/Destiner/blocksmith
for example :
...ANSWER
Answered 2021-Apr-07 at 02:38You have two choices in Electrum:
Importing a HD wallet (requires a seed, or mnemonic)
Importing a single address (requires the keypair for that address)
Using the cryptotools library from your second example:
QUESTION
I created an image with Docker using this Dockerfile and I pushed it to docker-hub.
ANSWER
Answered 2020-Sep-23 at 08:11The container in your pod exited with status 0 which means that the command in your container has successfully finished. You have not specified any restartPolicy for your container so the default is Always. Since your container finished - it will be restarted due to it's restart policy (actually you cannot even change that when using a deployment - it is always Always.
The deployment should be used when you have some long running processes and you want to make sure that all instances of those processees are up and can be rolled out to new versions if needed.
For one hit processes that do something and then quit - you might better use Jobs.
QUESTION
Sorry if this is a bit misleading, but I was actually doing this with Litecoin as opposed to Bitcoin, but the algorithm is exactly the same and I'm pretty sure that the answer will be too. In fact, am almost certain when I look, there's going to be the same problem with Bitcoin too. I'm having difficulty generating the correct SegWit address for a given public key as below:
Litecoin address generation (which is the same as Bitcoin)
- I take a compressed public key: 03861b83752e0c47cac36fc5980ae8956f41f6d9792a51f68a6bd5f66cc7364b48
- SHA256 on the public key.
- RipeMD160 the result from 2.
- Add a prefix byte, in my case, 0x3a which is the LTC_TESTNET
- Double SHA256 result of 4 and add the first four bytes of this result to the end of the RipeMD160.
- Finally, Base58 encode.
All seems dandy, right? Out pops the SegWit address: QhQxSZvVDWr3JvoKsYVC6BBW3DqkGhesrF
However, I'm pretty sure this address isn't right. When I import the private key into Electrum-LTC as a (p2wpkh-p2sh:) the address it generates for this private key is: QYyWqgyWSm1AJWph32GnyY7eamG1wUDruk
Now I believe that Electrum-LTC is right and there's something that I'm missing when generating a SegWit address and there's more to address generation than just changing the network prefix. My Public Key Hash is:
e444ac77800cdf904b928fc4642ab6fb6d4d696c
and Electrum-LTC's Public Key Hash is:
87b3e5bf5b2a1381e6549020d245e45b9ac76c82
Since the values are so VERY different, it suggests that the initial SHA256 is not hashing just the public key alone and that I'm missing something. I'm about out of ideas and am hoping someone has the answer and about the only thing I can find in the source, in the chainparams.cpp was this:
...ANSWER
Answered 2020-Jun-01 at 10:21Have finally figured this one out... When calculating a p2wpkh-p2sh address, it's not just the prefix of the address that is different. In actual fact, I found the answer to the above problem here: https://bitcoin.stackexchange.com/questions/72775/is-it-possible-to-convert-an-address-from-p2pkh-to-p2sh (although it is quite cryptic in how it is explained).
The above code in my question will work quite happily for p2pkh address generation for Bitcoin/Litecoin etc, but when generating a Q (for Litecoin), 2 (for Bitcoin), it won't work because it's not just the public key that is hashed. It's actually a script, of 0x00 (DUP_0) and then a length of the public key hash (0x14).
So, to fix the above code, if the address generation code is changed to:

Install electrum
You can use electrum like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
