QUESTION
I created the default IntelliJ IDEA React project and got this:
...ANSWER
Answered 2021-Nov-15 at 00:32Failed to construct transformer: Error: error:0308010C:digital envelope routines::unsupported
The simplest and easiest solution to solve the above error is to downgrade Node.js to v14.18.1. And then just delete folder node_modules
and try to rebuild your project and your error must be solved.
QUESTION
I am using a company-hosted (Bitbucket) git repository that is accessible via HTTPS. Accessing it (e.g. git fetch
) worked using macOS 11 (Big Sur), but broke after an update to macOS 12 Monterey.
*
After the update of macOS to 12 Monterey my previous git setup broke. Now I am getting the following error message:
...ANSWER
Answered 2021-Nov-02 at 07:12Unfortunately I can't provide you with a fix, but I've found a workaround for that exact same problem (company-hosted bitbucket resulting in exact same error).
I also don't know exactly why the problem occurs, but my best guess would be that the libressl library shipped with Monterey has some sort of problem with specific (?TLSv1.3) certs. This guess is because the brew-installed openssl v1.1 and v3 don't throw that error when executed with /opt/homebrew/opt/openssl/bin/openssl s_client -connect ...:443
To get around that error, I've built git from source built against different openssl and curl implementations:
- install
autoconf
,openssl
andcurl
with brew (I think you can select the openssl lib you like, i.e. v1.1 or v3, I chose v3) - clone git version you like, i.e.
git clone --branch v2.33.1 https://github.com/git/git.git
cd git
make configure
(that is why autoconf is needed)- execute
LDFLAGS="-L/opt/homebrew/opt/openssl@3/lib -L/opt/homebrew/opt/curl/lib" CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include -I/opt/homebrew/opt/curl/include" ./configure --prefix=$HOME/git
(here LDFLAGS and CPPFLAGS include the libs git will be built against, the right flags are emitted by brew on install success of curl and openssl; --prefix is the install directory of git, defaults to/usr/local
but can be changed) make install
- ensure to add the install directory's subfolder
/bin
to the front of your$PATH
to "override" the default git shipped by Monterey - restart terminal
- check that
git version
shows the new version
This should help for now, but as I already said, this is only a workaround, hopefully Apple fixes their libressl fork ASAP.

ANSWER

QUESTION
I am storing a public key in a env variable as a string. This public key is from a .pem file. When I try to use it in my code, I get the following error
...ANSWER
Answered 2022-Mar-28 at 08:47Your key seems to be a PEM encoded public key in X.509/SPKI format. However, the line breaks are missing. These are to be set so that header and footer are each on a single line. In the body there is a line break after every 64 characters.
A correctly formatted PEM key can be processed directly by createPublicKey()
. The key will be accepted even if the line breaks in the body are missing, but header and footer must be in different lines, otherwise the posted error message will be displayed: error:0909006C:PEM routines:get_name:no start line.

...ANSWER
Answered 2021-Dec-21 at 09:19This looks like a new issue with many packages including web3 as these are not compatible with Webpack v5 without adding fallbacks for the polyfils.
Issue noted here: https://github.com/facebook/create-react-app/issues/11756
I solved this issue by adding the fallback to my webpack.config.js file;

QUESTION
I'm experimenting with Chaum's blind signature, and what I'm trying to do is have the blinding and un-blinding done in JavaScript, and signing and verifying in Java (with bouncy castle). For the Java side, my source is this, and for JavaScript, I found blind-signatures. I've created two small codes to play with, for the Java side:
...ANSWER
Answered 2021-Dec-13 at 14:56The blind-signature library used in the NodeJS code for blind signing implements the process described here:
BlindSignature.blind()
generates the SHA256 hash of the message and determines the blind message m' = m * re mod N.BlindSignature.sign()
calculates the blind signature s' = (m')d mod N.BlindSignature.unblind()
determines the unblind signature s = s' * r-1 mod N.BlindSignature.verify()
decrypts the unblind signature (se) and compares the result with the hashed message. If both are the same, the verification is successful.
No padding takes place in this process.
In the Java code, the implementation of signing the blind message in signConcealedMessage()
is functionally identical to BlindSignature.sign()
.
In contrast, the verification in the Java code is incompatible with the above process because the Java code uses PSS as padding during verification.
A compatible Java code would be for instance:
QUESTION
After upgrading my Angular from 12.0.2 to 13.0.3 everything was working fine. I was trying to remove some packages that was not used such as jquery
, and some other i do not remember etc. and after that I deleted node_modules
, package-lock.json
and run npm i
to installed all packages again. After that I recieved bunch of errors which then i again reverted package.json and tried npm i then I am getting below errors. And I am unable to fixed it.
Any idea how can i resolve this ?
...ANSWER
Answered 2022-Feb-25 at 06:57As I researched a lot and did not find a solution to this issue as it's occurring only on the newer version of the animation package.
I tried the below versions:
13.2.4 (Latest one) throwing same es error
13.2.3 throwing same es error
13.2.2 throwing same es error
13.2.1 throwing same es error
13.2.0 working without error.
So I think for a temporary fix you should update your package.json
by pointing to a specific version of this npm
like below.

Answered 2021-Aug-22 at 15:41Since you're already using Docker
, I'd suggest using a multi-stage build. Using a standard docker image like golang
one can build an executable asset which is guaranteed to work with other docker linux images:
