QUESTION
(there are a fair few fairly similar posts - I've read them, the solutions largely seem to be about Python string encoding, which I thought I had under control but clearly still don't)
I'm trying to port an NPM package to Python, but I can't get the same results from each script. I've stripped it down to this:
...ANSWER
Answered 2020-Feb-11 at 18:41That is certainly correct that for the same given input the hash function produces the same digest. However, where it gets tricky is that many of those hash functions accept the input in terms of bytes. That means here the encoding the giving string into different is dependent on the platform. However, you also need to take into account that different programming languages might have subtle differences, for example I'm not familiar with python, but it might be adding an empty space at the end of the input and/or use different Unicode representations for different special characters. Even one byte change in the input would produce a completely different output, as one might expect from a hash function.
To sum it up, should you want to find why a different hash is created, you should perform a binary comparison of the input of the hash functions. Or print out the input for the SHA-256 in hexadecimals or base 64.
QUESTION
I was using Expo
and I separated expo eject
for module use.
And I tried pod install
in iOS file. it was work.
Pod installation complete! There are 51 dependencies from the Pod file and 63 total pods installed.
But An error occurred when the Xcode
was opened and the build and run
button was pressed.
package.json:
...ANSWER
Answered 2019-May-08 at 09:04I made a podsec
myself and solved it.
This is not in the official document and requires a fundamental solution from the module developer.
This solution creates a lot of Warning
. There's nothing wrong with the code.
- Remove
react-native-secure-randombytes
path from Header Search Path - Unlink
react-native-secure-randombytes
module - react-native unlink react-native-secure-randombytes - Added react-native-secure-randombytes.podspec from this link
Added next code into pod file:
pod 'react-native-secure-randombytes', :path => '../node_modules/react-native-secure-randombytes'
- do `pod install'
QUESTION
I'm using some unpopular modules such as Dyo
and js-sha3
which doesn't have any types, it seems.
I don't really care right now about types in third-party libraries, I don't want to spend hours typing those. I mainly use it for the server to limit my mistakes and make troubleshooting easier while in development.
I had a Cannot find module X
error before so I've added: "moduleResolution": "node"
in my tsconfig.json file.
How can I make typescript not complaining about node modules missing types?
The whole error:
...ANSWER
Answered 2019-Jan-14 at 00:14You can create dummy .d.ts
definition which will allow to import anything from the module - importing it will result in dyo
having any
type (the exact way to import it depends on the esModuleInterop
compiler setting, and on how the things are exported from dyo.umd.js
).
create a file
dyo.d.ts
somewhere within your project with one line in it
QUESTION
I have been unable to fix this error or determine the cause. No code has changed, so I assume it is a result of an NPM package being updated. Here is the error log to the console. This is for an Angular2 application.
...ANSWER
Answered 2017-Aug-17 at 04:07I ran into this same issue yesterday when I cloned a repo onto a new machine and did an NPM install to get the packages - same exact error. My project is also using the ng2-semantic-ui package. Ng2-semantic-ui has a dependency on both Popper.js and @types\popper (typescript definitions).
QUESTION
I can't seem to obtain the exact algorithm that would generate all the round constants for SHA-3.

...ANSWER
Answered 2017-May-26 at 17:11The reason LFSR
is a byte[]
in the Java version is to allow LFSR86540
to modify it. You can make the function return the new value instead:
