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.

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:

I'm deploying a spring-boot application and prometheus container through docker, and have exposed the spring-boot /actuator/prometheus
endpoint successfully. However, when I enable prometheus debug logs, I can see it fails to scrape the metrics:
ANSWER
Answered 2022-Feb-07 at 22:37Ok, I think I found my problem. I made two changes:
First, I moved the contents of the web.config.file into the prometheus.yml file under the 'spring-actuator'. Then I changed the target to use the hostname for my backend container, rather than 127.0.0.1.
The end result was a single prometheus.yml file:

I'm trying to create a Printing Server in rust and face a problem when trying to send JSON as a response.
I've found on the Rocket documentation that is really easy to send JSON as a response: You just have to use the Serde library.
Unfortunatly, that wasn't so simple for me...
Here is my current code :
...ANSWER
Answered 2021-Aug-06 at 14:23You are using rocket 0.5.0-rc.1 and rocket_contrib 0.4.10. While Json
from rocket_contrib does implement Responder
, it implements the Responder
trait of Rocket v4, not that of Rocket v5.
In Rocket v5, Json
is not part of rocket_contib
anymore, but included in the rocket
crate (note that you need to enable the json
feature on the rocket
crate):
QUESTION
Environment:
...ANSWER
Answered 2022-Jan-25 at 07:13Git For Windows 2.33.1 comes with OpenSSH 8.8 which disables RSA signatures using the SHA-1 hash algorithm by default.
For most users, this change should be invisible and there is no need to replace ssh-rsa keys.
OpenSSH has supported RFC8332 RSA/SHA-256/512 signatures since release 7.2 and existing ssh-rsa keys will automatically use the stronger algorithm where possible.Incompatibility is more likely when connecting to older SSH implementations that have not been upgraded or have not closely tracked improvements in the SSH protocol.
For these cases, it may be necessary to selectively re-enable RSA/SHA1 to allow connection and/or user authentication via the HostkeyAlgorithms and PubkeyAcceptedAlgorithms options.
For example, the following stanza in ~/.ssh/config will enable RSA/SHA1 for host and user authentication for a single destination host:
QUESTION
Trying to install openssl on homebrew using:
...ANSWER
Answered 2021-Sep-03 at 15:29Seems a bug of openssl itself. https://github.com/openssl/openssl/issues/16487
~~What about export SDKROOT="/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk "
?~~
Homebrew pre-build packages for some versions of macOS. But it keep dropping this pre-building support for old macOS. On macOS 10.12, you're building openssl
from the source code and Xcode command line tool is needed.
QUESTION
I'm trying to get MariaDB4J working on my new M1 MacBook Pro, and I'm not doing so great.
I am running the Arm versions of both libssl@1.1 and mariadb 10.6.4, both installed with Homebrew.
First I had issues with libssl not finding libssl, it had to have 1.0, so i installed symlinks from the 1.0 path the library expects to the homebrew 1.1 destination. According to various issue threads on the mariadb GitHub page this should work.
So, it indeed resulted in that libssl was found, but now I get another issue in the logs:
"Reason: tried: '/usr/local/opt/openssl/lib/libssl.1.0.0.dylib' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'))"
So, I guess that something/mariadb4j expects the x86 version of libssl but I have arm? I'm not sure how to sort this out, so hoping that someone got this to work on M1. Pointers appreciated.
...ANSWER
Answered 2021-Nov-29 at 00:36I'm the author of MariaDB4j, and can confirm that currently this is not possible / won't "just work". The reason is that what MariaDB4j does is simply package platform specific MariaDB binaries into JARs, and then natively exec
utes the mysqld
. And nobody has contributed the MariaDB binaries for M1 to MariaDB4j... but contributions to the project are very welcome! ;-) https://github.com/vorburger/MariaDB4j/issues/497 tracks this FR.
