I'm new in ASP.NET.
Environment:
Ubuntu 18.04
Visual Studio Code
.NET SDK 2.2.105
I'm in trouble with some command running.
I was reading tutorial at
https://learn.microsoft.com/ja-jp/aspnet/core/tutorials/razor-pages/razor-pages-start?view=aspnetcore-2.2&tabs=visual-studio-code
and ran this command:
dotnet dev-certs https --trust
I expect https://localhost should be trusted.
but I found the error message;
$ Specify --help for a list of available options and commands.
It seems that the command "dotnet dev-certs https" has no --trust options.
How to resolve this problem?
On Ubuntu the standard mechanism would be:
dotnet dev-certs https -v to generate a self-signed cert
convert the generated cert in ~/.dotnet/corefx/cryptography/x509stores/my from pfx to pem using openssl pkcs12 -in <certname>.pfx -nokeys -out localhost.crt -nodes
copy localhost.crt to /usr/local/share/ca-certificates
trust the certificate using sudo update-ca-certificates
verify if the cert is copied to /etc/ssl/certs/localhost.pem (extension changes)
verify if it's trusted using openssl verify localhost.crt
Unfortunately this does not work:
dotnet dev-certs https generates certificates that are affected by the issue described on https://github.com/openssl/openssl/issues/1418 and https://github.com/dotnet/aspnetcore/issues/7246:
$ openssl verify localhost.crt
CN = localhost
error 20 at 0 depth lookup: unable to get local issuer certificate
error localhost.crt: verification failed
due to that it's impossible to have a dotnet client trust the certificate
Workaround: (tested on Openssl 1.1.1c)
manually generate self-signed cert
trust this cert
force your application to use this cert
In detail:
manually generate self-signed cert:
create localhost.conf file with the following content:
[req]
default_bits = 2048
default_keyfile = localhost.key
distinguished_name = req_distinguished_name
req_extensions = req_ext
x509_extensions = v3_ca
[req_distinguished_name]
commonName = Common Name (e.g. server FQDN or YOUR name)
commonName_default = localhost
commonName_max = 64
[req_ext]
subjectAltName = #alt_names
[v3_ca]
subjectAltName = #alt_names
basicConstraints = critical, CA:false
keyUsage = keyCertSign, cRLSign, digitalSignature,keyEncipherment
[alt_names]
DNS.1 = localhost
DNS.2 = 127.0.0.1
generate cert using openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout localhost.key -out localhost.crt -config localhost.conf
convert cert to pfx using openssl pkcs12 -export -out localhost.pfx -inkey localhost.key -in localhost.crt
(optionally) verify cert using openssl verify -CAfile localhost.crt localhost.crt which should yield localhost.crt: OK
as it's not trusted yet using openssl verify localhost.crt should fail with
CN = localhost
error 18 at 0 depth lookup: self signed certificate
error localhost.crt: verification failed
trust this cert:
copy localhost.crt to /usr/local/share/ca-certificates
trust the certificate using sudo update-ca-certificates
verify if the cert is copied to /etc/ssl/certs/localhost.pem (extension changes)
verifying the cert without the CAfile option should work now
$ openssl verify localhost.crt
localhost.crt: OK
force your application to use this cert
update your appsettings.json with the following settings:
"Kestrel": {
"Certificates": {
"Default": {
"Path": "localhost.pfx",
"Password": ""
}
}
}
While the answer provided by #chrsvdb is helpful it does not solve all problems. I still had issue with service-to-service communication (HttpClient - PartialChain error) and also you must reconfigure Kestrel to use your own certificate. It is possible to create a self-signed certificate and import it to the .NET SDK. All you need is to specify the 1.3.6.1.4.1.311.84.1.1 extension in the certificate.
After that the cert can be imported into .NET Core SDK and trusted. Trusting in Linux is a bit hard as each application can have it's own certificate store. E.g. Chromium and Edge use nssdb which can be configured with certutil as described John Duffy. Unfortunately the location to the nssdb maybe different when you install application as snap. Then each application has its own database. E.g. for Chromium Snap the path will be $HOME/snap/chromium/current/.pki/nssdb, for Postman Snap the will be $HOME/snap/postman/current/.pki/nssdb and so on.
Therefor I have created a script which generates the cert, trusts it for Postman Snap, Chmromium Snap, current user nssdb and on system level. It also imports the script into the .NET SDK so it will be used by ASP.NET Core without changing the configuration. You can find more informations about the script in my blog post https://blog.wille-zone.de/post/aspnetcore-devcert-for-ubuntu
In adition to crisvdb answer, I've several information to add and is the continuation of the walktrough. I don't comment because is pretty complex comment this, but before this answer take a look to crisvdb answer first and then return to continue.
Take the "in detail" crisdb answer.
You can make your cert in any folder, can be or can't be in the same folder of the app.
Take openssl verify -CAfile localhost.crt localhost.crt as not optional step, mandatory. It will help.
Do not recompile or touch the code meanwhile you are doing this, in order to get first scenario clean.
If you run sudo update-ca-certificates that will answer you in wich folder the certified should be copied.
In some distributions, as Raspbian for Raspberry Pi, CA certificates are located in /etc/ssl/certs as well as /usr/share/ca-certificates/ and in some cases /usr/local/share/certificates.
Do not copy the cert manually to trusted certs, run sudo update-ca-certificates after you copy the cert in the right folder. If it doesn't work (doesn't update or add any certificate) copy it to every folder possible.
If you use a password while making the certificate, you should use it in the appsettings.json
If you get this error:
Interop+Crypto+OpenSslCryptographicException: error:2006D002:BIO
routines:BIO_new_file:system lib
Take in consideration that error means "access denied". It can be because you don't have permissions or related.
7b) Could be also that the file is not found, I use the entire path in the config:
"Path": "/home/user/www/myfolder1/myapp/localhost.pfx",
After that, and if everything works, you could see a 500 error if you are using Apache or Apache2.
If you get the following error in the apache logs of the site:
[ssl:error] [remote ::1:yourport] AH01961: SSL Proxy requested for
yoursite.com:443 but not enabled [Hint: SSLProxyEngine] [proxy:error]
AH00961: HTTPS: failed to enable ssl support for [::1]:yourport
(localhost)
you must set in the VirtualHost the following configuration after SSLEngine On and before your ProxyPass
SSLProxyEngine on
After that, and if everything works, you could see a 500 error if you are using Apache or Apache2.
If you get the following error in the apache logs of the site:
[proxy:error] [client x.x.x.x:port] AH00898: Error during SSL
Handshake with remote server returned by /
[proxy_http:error] [client x.x.x.x:port] AH01097: pass request body failed to [::1]:port
(localhost) from x.x.x.x()
you must set in the VirtualHost the following configuration after SSLProxyEngine on and before your ProxyPass
SSLProxyVerify none
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
UPDATE
If you are renovating this, and using the same names, take in consideration that you should remove your pem file from etc/ssl/certs
UPDATE 2
If it returns:
Unhandled exception. Interop+Crypto+OpenSslCryptographicException: error:2006D002:BIO routines:BIO_new_file:system lib
Check that your pfx file is on 755 permissions.
If appsettings.json seems to be don't load (on port 5000 by default or SQL or any configuration doesn't load or can't be read), take in consideration that the dotnet must be executed on the same directory where is appsettings.json
Looks like this is a known issue with dotnet global tools and that specific command is only available for MacOS and Windows. See this issue on github: Issue 6066.
It seems like there may be a work around for Linux users based on this SO post: ASP.Net Core application service only listening to Port 5000 on Ubuntu.
For Chrome:
Click "Not Secure" in address bar.
Click Certificate.
Click Details.
Click Export.
Run: certutil -d sql:$HOME/.pki/nssdb -A -t "P,," -n {FILE_NAME} -i {FILE_NAME}
Restart Chrome.
It looks like the following could help to trust the dotnet dev certs:
https://blog.wille-zone.de/post/aspnetcore-devcert-for-ubuntu/
Then you will see also in the browser that certificate is OK and valid for the next yeat.
Give it a try...
Good luck!
I have just installed an intermediate & primary SSL certificate on my VPS. Everything is working well, except when I make a cfhttp call:
<cfhttp url="https://advert.establishmindfulness.com/ad-zone-1/?categoryid=1" method="get" result="adzone" />
<cfdump var="#adzone#" />
From https://app.establishmindfulness.com to https://advert.establishmindfulness.com. These 2 subdomains are on the same server, and I am using a wildcard SSL certificate:
*.establishmindfulness.com
That covers all sub domains.
VPS environment
OS: Windows 2008R2 with IIS7
Application server: Lucee 4.5.2.018 final
Servlet Container: Apache Tomcat/8.0.28
Java: 1.8.0_66 (Oracle Corporation) 64bit
Do I need to install the intermediate.crt & primaryssl.crt into my keystore cacerts? Is this the problem?
I tried just installing the certificate.cer that I grabbed from Internet Explorer, but maybe this is the wrong approach?
I still get the error:
Error Detail
Unknown host: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
OK. For anyone who comes across this issue, instead of having to spend several hours pulling your hair out, I managed to get the connection to work:
This is taken from the following link:
https://groups.google.com/forum/#!topic/lucee/BPm8vYdgkPQ
Thank you Dominic Watson
I've just tried this and got it working:
Log in to Lucee server admin and navigate to "SSL Certificates"
Enter your host name "establishmindfulness.com" in the Host field (without the quotes)
Hit "list" button
Hit "install" button
That's it. The cfhttp call started working.
We are using centos7 .If tried the below way with pem file included scp works but when pem file is removed its not working. Code was working earlier without pem file . After We moved to a different web server we are having Host key verification failed issues.
scp -i/home/centos/sshkeys/test.pem root#77.79.77.72:/usr/local//2016/Aug/31/ggea98c0-6f0f-11e6-86d9-2573a2e556aa.wav /var/www/html/tmp/ggea98c0-6f0f-11e6-86d9-2573a2e556aa.wav
Maybe your key was registered in ~/.ssh/config or it was your default key in ~/.ssh ? Check on the old server ?
Edited:
For example this is what I put in ~/.ssh/config
Host myserver
Hostname 52.100.100.100
User ubuntu
IdentityFile ~/dev/application/server-key.pem
It allow me to connect simply by ssh myserver. Maybe it was something like this that you had on your server.
I have executed below unix commands to add certificate in node truststore on websphere 7.0.
Can you please help me how can I add certificate in cell truststore.
I executed the below commands:
was70nd -profile cert_add (key | trust) [-n ]
[-pwd ] -signer -alias -f
Thanks in advance
You can add the certificate through the WAS Admin Console. Go to following Location
Menu --> Security --> SSL certificate and key management --> click on Key stores and certificates --> click on the desired truststore --> click on the Signer certificates.
From here you can import your certificate into the WebSphere truststore.
Hi I am trying to load web page in webView pannel in JAVAFX.
I am able to load the web page whose certification is valid like google,yahoo. But unable to load invalid certification Sites.
Please suggest how can I add certification to my Web Site.
Thanks.
This is because the certificate cannot be found in default java certificates store.
Try to create java truststore with the root certificate from the "invalid certification sites". Command similar to this:
keytool -importcert -trustcacerts -alias somealias -file certificate.crt -deststorepass somePassword -destkeystore truststore.jks
Then start your java program with VM options:
-Djavax.net.ssl.trustStore="pathto\truststore.jks" -Djavax.net.ssl.trustStorePassword="somePassword" -Djavax.net.debug=all
Additional option -Djavax.net.debug=all allows you to debug the ssl handshake and see potential errors with certificates.
