I know there are some other questions (with answers) to this topic. But no of these was helpful for me.
I have a postfix server (postfix 3.4.14 on debian 10) with following configuration (only the interesting section):

Answered 2021-Jun-15 at 08:30Here I'm wondering about the line [in s_client]
New, TLSv1/SSLv3, Cipher is ECDHE-RSA-AES256-GCM-SHA384
You're apparently using OpenSSL 1.0.2, where that's a basically useless relic. Back in the days when OpenSSL supported SSLv2 (mostly until 2010, although almost no one used it much after 2000), the ciphersuite values used for SSLv3 and up (including all TLS, but before 2014 OpenSSL didn't implement higher than TLS1.0) were structured differently than those used for SSLv2, so it was important to qualify the ciphersuite by the 'universe' it existed in. It has almost nothing to do with the protocol version actually used, which appears later in the session-param decode:
QUESTION
We are programmatically creating PDF using our in house lib (C++) by adding all the required objects so that PDF readers can render them properly. Currently we are enhancing the lib to support digital signatures in PDF. Our users will use USB token or Windows certificates to sign the PDF. On studying raw PDF file with digital signature, we were able to make sense of all the objects except for the contents of Sig type object.
...ANSWER
Answered 2021-Jun-10 at 16:48Ok, the signature container is embedded correctly.
But there are issues with the signature container itself:
Both in the
SignedData.digestAlgorithmscollection and in theSignerInfo.digestAlgorithmvalue you have used the OID of SHA1withRSA, but that is a full signature algorithm, not the mere digest algorithm SHA1 expected there.Then the SHA1 hash of the signed bytes is BB78A402F7A537A34D6892B83881266501A691A8 but the hash you signed is 90E28B8A0D8E48691DAFE2BA10A4761FFFDCCD3D. This might be because you hash buffer2 and
buffer2 has empty contents data (/Contents <>)
The hex string delimiters '<' and '>' also belong to the contents value and, therefore, must also be removed in buffer2.
Furthermore, your signature is very weak:
- It uses SHA1 as hash algorithm. SHA1 meanwhile has been recognized as too weak a hash algorithm for document signatures.
- It doesn't use signed attributes, neither the ESS signing certificate nor the algorithm identifier protection attribute. Many validation policies require such special attributes.

I has to install spring security in my grails 3 application and started receiving that known error which should be resolved by replacing grails-wrapper.jar.
That is the error:
...ANSWER
Answered 2021-Jun-14 at 19:20I believe that this is all related to the repo URL problems over the last week or so. More info is here https://github.com/grails/grails-core/issues/11825 but in general it sounds like the http URLs are either going away, or gone already.
Specifically reference https://github.com/grails/grails-core/issues/11825#issuecomment-859692299 in which Jeff Brown states
If the HTTP URLs do resume working without a redirect that will be for a limited period. I would not suggest reverting any updates you have already made to the HTTPS repository URLs. I would also strongly consider taking the time to update your remaining applications.
Change to https and come back with whatever problems you run into then...I would expect someone here can help work through those.
QUESTION
Short Summary: This app works on a physical android phone. However, when we try to make it work on the emulator, Google Sign In does not work. Please see the details below:
Details:
We have created a Flutter app to share information to our internal team.
Pre Google Play Store Update: At the start, we connected Firebase to the app. Added the debug SHA 1 key to Firebase. Google Sign-In works as expected in both the emulator and phone.
Post Google Play Store release: a. List item
a. We deleted the debug SHA1 from Firebase and changed the SHA1 key to the key which Google Play store gives us.
b. Downloaded the new google-services.json from Firebase and added it to our androip/app folder. The Google Sign in Works on the Phone but does not work via the Emulator. We get the following error:
I/flutter (24658): PlatformException(network_error,com.google.android.gms.common.api.ApiException: 7: , null, null)
We re-added the Debug SHA1, and Debug SHA256 keys to Firebase. Still, Google Sign in does not work on the Emulator. But works properly in the Phone.
Checked about 7 previous StackOverflow response, but most responses are for PlatformException(sign_in_failed...) or other reasons, but not for PlatformException(network_error...) . examples of solutions tried:
Google sign in failed com.google.android.gms.common.api.ApiException: 10:
Internet permissions is enabled in the AndroidManifest.xml
Please let us know if any code is to be shared to analyse the issue better and we will share it.
Thank you in advance.
...ANSWER
Answered 2021-Jun-13 at 15:32You are probably now building a release version to install on the emulator in Android Studio, but you don't have the release sha-1 shared with Firebase. Add all three sha-1 to Firebase: Debug and Release sha-1 from Android Studio, and sha-1 from the Play Store. Then download and install the new google-services.json from Firebase and add it to your android/app folder. Then clean and rebuild your app. All versions of your app should then work with Firebase and Google sign in.
QUESTION
I am working on setting up git repositories on a windows server (2019), attempting to follow https://git-scm.com/book/en/v2/Git-on-the-Server-Setting-Up-the-Server. However, no matter what I do, git push comes up with fatal: ''/Users/testing/testrepo.git'' does not appear to be a git repository.
I ran:
git init
git add test.txt (test file, just contained test)
git commit -m "test"
git remote add origin testing@(removed):Users/testing/testrepo.git
git push origin master
After struggling with this for a while, I enabled logging for ssh and found this line on the server side log file:
7744 2021-06-09 03:58:37.691 debug1: Executing command: "c:\windows\system32\cmd.exe" /c "git-receive-pack '/Users/testing/testrepo.git'" with no pty
I tried manually running git-recieve-pack '/Users/testing/testrepo.git', and it came up with the same error. However, I then tried running git-receive-pack "/Users/testing/testrepo.git", and it gave

0000
The only difference was " instead of '. Is this something weird with windows server, or am I doing something wrong?
ANSWER
Answered 2021-Jun-11 at 13:10Turns out it was an issue with the ssh server I was using: https://github.com/PowerShell/Win32-OpenSSH/issues/752. One of the workarounds in the comments was to set the git receivepack and uploadpack commands to use powershell, but since I didn't want to change that for my global git config or have to do it for every repository I found a better solution. Following https://docs.microsoft.com/en-us/windows-server/administration/openssh/openssh_server_configuration, I added a key to HKLM:\SOFTWARE\OpenSSH: DefaultShell = "C:\windows\System32\WindowsPowerShell\v1.0\powershell.exe". Now ssh commands go to powershell by default on that server, which fixed the issue with git-receive-pack.
QUESTION
To secure and monitor our GCP cloud functions we integrated the GCP api gateway .
The android app has to pass the SHA1 fingerprint, package name and the api key as part of the request to get authenticated.
Is it safe to do this way?
https://cloud.google.com/api-keys/docs/add-restrictions-api-keys
https://cloud.google.com/docs/authentication/api-keys#api_key_restrictions
...ANSWER
Answered 2021-Jun-10 at 20:41To answer this question, you can ask yourselves: Is someone can decompile my APK and extract the API key and the sha-1 from my code?
Sadly, yes...
Thus, this is enough to make the assumption that's your app which make the request, but you need to add a dedicated authentication mechanism to authenticate the users (firebase auth)
Finally, all depends on is it safe for what?

So I need to do a select statement, while encrypting a field in SHA2_512. I'm not sure which DB2 version it is, but I tried both queries and neither work.
When trying this query:
...ANSWER
Answered 2021-Jun-10 at 15:28You appear to be using Db2-v11 for Z/OS "DSN11015" in V11 compatibility mode.
This version lacks the scalar function HASH_SHA256 (and others) which is present in Db2-v12 for z/OS. That is the reason you get sqlcode -440 (no such function HASH...) with your Db2-for-z/os version.
At Version-11 , IBM documents a function ENCRYPT_TDES which may help you.
Background information on using this function.
You can write your own functions if you have the skills.

I'm having an issue with storing the original file name both in the database and in disk storage. The file saves correctly in the database and in the Nova backend, but in the disk storage is just saves as a random string.
In the database: my-user-friendly-file-name.pdf
In the disk storage: kfnakfncanjnaskdmkasniodanwjioeocniosandoaisndcacs.pdf
I have followed the docs, and it seems the below code should work but it doesn't.

Answered 2021-Jun-08 at 12:37So just as @ceejayoz said I ended up storing an extra column for the original file name and then call that in your code where needed, in my case emailing out attachments.
