QUESTION
Secret of Time-based One Time Password are usually 16-byte base32 encoded string. e.g. GitHub 2FA.
But for some scenario, it has 26 bytes long. e.g. Tutanota OTP. Often in lower case with whitespaces, like: vev2 qjea un45 3sr4 q4h3 ais4 ci
I tried with the TOTP algorithm implemented in dgryski/dgoogauth and tilaklodha/google-authenticator. Both can handle 16-byte secret well, but got error for 26-byte secret.
e.g. for 16-byte secret VEV2QJEAUN453SR4:
ANSWER
Answered 2022-Apr-02 at 04:15A base32 encodes every 5 bits of input bytes into base32 character, go base32 use The RFC 4648 Base 32 alphabet (A-Z, 2-7). When decode a string to bytes, each base32 character input will be mapped to a 5 bit index then recompose to bytes.
In your example "VEV2QJEAUN453SR4Q4H3AIS4CI", the previous "VEV2QJEAUN453SR4" was already valid input, it is a 16 char input, and 5 bit * 16 is 80 bit so it can be resolved into 10 bytes output. Now let us just look at the rest "Q4H3AIS4CI", 10 char -> 5 * 10 = 50 bits, the previous 40 bits can be decode to 5 bytes, but the last 2 char "CI" leads 2 bit remainder
QUESTION
im trying to make my own api and one part of it is that I want it to be able to receive text and files from a discord webhook, the text part works fine but when I send the file I can't seem to figure out how to receive it. I looked around for a bit and saw that req.files will return the file but I just get undefined. Here is my api code:
ANSWER
Answered 2022-Feb-22 at 14:56Upload files (e.g. how requests does it) are sent as multipart/form-data payloads.
As per body-parser's npm page,
[...] does not handle multipart bodies, due to their complex and typically large nature. For multipart bodies, you may be interested in the following modules...
You'll need one of those modules, and you'll then need to read its documentation to see if it provides eg. the req.files you've seen somewhere. Otherwise it will indeed be undefined.
QUESTION
Both base32 and base64 CLI utils are part of gnu coreutils. So, why not add a base16?
...ANSWER
Answered 2021-Dec-20 at 08:39GNU coreutils is free. It's people very, very hard work they are doing for free. You are using it completely for free. How much have you donated? Donate them. Pay them if you want something.
Why not add a base16 into coreutils?
It costs work, both implementing, but mostly the never ending maintenance. If something is not needed, it's better not to add it and reduce the work and concentrate on what's important. Maintaining current commands, so they are up-to-date with all systems and be consistent and work, is way more important. Some even say, that (especially in open-source) a project leader has most importantly decide what features to reject, not which to add.
So, how much will you pay for implementing and then endless maintaining a base16 utility in GNU coreutils?

I am trying to generate hd wallet private keys , public keys and addresess using cosmos sdk. Below is the equivalent implementation in python which generates the keys , address as expected but when trying to generated in golang using cosmos sdk it won't generate same keys. Any inputs for equivalent golang version of the python implementation is much appreciated. Thank you.

Answered 2022-Feb-13 at 16:24The results of both codes differ because of two issues:
In the Go Code, the private key is derived incorrectly:
In the Python code, the path
m/44'/118'/0'/0/0'is used, as the output ofhdwallet.path()shows. In the Go code, in contrast, the pathm/44'/118'/0'/0/0is used, as shown by the output ofpath.String().To use the path of the Python code in the Go code, the path can be e.g. specified directly. For this the line:
QUESTION
I was trying out some different encodings and as I tried to encode some text repeatedly in base64/base32 (which one is used depends on a semi-random boolean list) I noticed that it was ridiculously slow which I didn't understand because I thought that they were particularly fast. I can't really figure out why it's so slow, it'd be cool if you could help me.
This is the part of the code concerned :
...ANSWER
Answered 2022-Feb-07 at 12:51Memory and time expensive operations. The answer is based on pivotal comment (by Wups):
If you encode bytes with
base64, the result is longer than the input. If you take this result and encode it again in a loop, you have exponential growth.
The following modified script shows growing ratio for base64 and base32 encodings:

What am i doing So I'm trying to reply to a command interaction with a QR code, and I don't want to save the file to the directory of the bot and then send it that way, instead, I have the QR code text, and I'm using the QR Code package to convert it into a QR Code, and now I'm trying to write the file to a node stream.
What is the problem
The problem is I don't know how to access that file, since when I try to use { files: [returned.qrcode] } it doesn't send an image attachment.

QUESTION
I'm relatively new to Spectron and Jest and I can't figure out why the app isn't launching when I call app.start() in my unit test. Right now when I run npm test, the app won't start, eventually times out (even after 30 seconds) and always sends this error message:
Timeout - Async callback was not invoked within the 15000 ms timeout specified by jest.setTimeout.Error: Timeout - Async callback was not invoked within the 15000 ms timeout specified by jest.setTimeout. at mapper (node_modules/jest-jasmine2/build/queueRunner.js:27:45)
So far I've tried:
- making sure I'm using the correct versions of spectron and electron (11.0.0 and 9.0.0 respectively)
- running npm test from my root folder, my src folder, and my tests folder.
- deleting my node_modules folder, reinstalling everything, and rebuilding the app.
- using
path.join(__dirname, '../../', 'node_modules', '.bin', 'electron')as my app.path.
Here's my test1.js file:

Answered 2021-Sep-08 at 20:05I came across this Spectron tutorial on YouTube: https://www.youtube.com/watch?v=srBKdQT51UQ
It was published in September 2020 (almost a year ago as of the time of this post) and they suggested downgrading to electron 8.0.0 and Spectron 10.0.0. When I downgraded, the app magically launched when app.start was called.

...ANSWER
Answered 2021-Sep-07 at 18:34Jest won't use the babel plugins out of the box, you need to install some additional packages.
With yarn:
yarn add --dev babel-jest babel-core regenerator-runtime
With npm:
npm install babel-jest babel-core regenerator-runtime --save-dev
Jest should then pick up the configuration from your .babelrc or babel.config.js.

QUESTION
I am trying to write a script to calculate base32 strings out of provided ByteString values which I get as key value pairs. The ByteString makes use of octal escape sequences AND backslash escape sequences.
Consider this script:
...ANSWER
Answered 2021-Aug-26 at 15:44printf can't be used without a format string : when you call it with a single argument, that argument is parsed as the format.
Consider its synopsys in man bash :
printf [-v var] format [arguments]
It's the arguments list that is optional, not the format.
man bash goes on saying that plain characters found in the format string are copied as-is to the output stream, which is why you can use printf 'message' as you would echo 'message'.
However, it also adds that it will identify character escape sequences to convert them before printing (which is similar to what echo -e would do) and most importantly, "format character sequences" (%X substrings) which it will replace by the (possibly transformed) additional parameters, or a default value if there is no parameter left to consume.
This is the reason why you shouldn't printf "$message" : your $message might contain sequences of characters that will be interpreted by printf.
If you want to print a message as-is, you will want to use printf '%s' "$message", where %s is the format specifier that asks printf to ouput the (text) parameter as text (so, to output it unmodified).
QUESTION
What is the equivalent of b32encode in python in bash?
...ANSWER
Answered 2021-Aug-07 at 01:48In python, the expression \ooo is an octal literal (see "String and byte literals"), so the expression \327 produces the value 215 (hex D7).
On the other hand, in the shell echo "\327" produces the literal value \327.
Since you're not encoding the same data in your two examples, you're getting different results.
The shell equivalent to your Python example would be:
