I use the following script the generate certificate
openssl req -new -keyout out/$I.key -out out/$I.request -days 365 -nodes -subj
"/C=US/ST=California/L=Irvine/O=example com/CN=${I}" -newkey rsa:2048
My complete script I use (you can refer but I can not support the script for
your need)
https://github.com/dmilan77/scripts/blob/master/ssl/createSSLCert.sh
You can verify using nmap or oepnssl
openssl s_client -connect hostname:443 -tls1_2
nmap --script ssl-enum-ciphers -p 443 hostname

I am using openssl for creating SSL certificate but I am unable to figure

Could you please help me out on this. I am not aware much about these

Hi Bajendra,
TLS vs SSL is all depends on how you generate the SSL certificates.
If the SSL certificate is TLS 1.2 then JVM SSL protocol will use TLS.

Hi Andy,
Thanks a lot for you valuable inputs. I could found the actual
resolution after debugging the issue.
Earlier I was using IBM java 8 instead of Oracle Java 8/open JDK 8,
where SSLv3 Protocol is not enabled by default, hence I was facing this issue.
Now I am able to see the NiFi UI securely but please let me know the
way where I can run this nifi on TLS 1.0, 1.2 protocol instead of SSLv3 so I
can use IBM Java 8 as well?

Apache NiFi does not support Basic Authentication in any scenario.
There are multiple options for user authentication to the NiFi UI/API,
including LDAP, Kerberos, client certificates, Apache Knox, and OpenID Connect.
More details about configuring these options are available in the Admin Guide
[1].
As for your TLS error, my guess is that there is an error with the
certificate you generated. The error “No overlapping cipher suites available”
can occur when the certificate is expired or otherwise invalid, and all the
available cipher suites require an RSA key for signing or encryption. To
further debug this, you can use the OpenSSL s_client tool to attempt to make a
connection via the command line, and enable the JSSE SSL debugging via a
modification to bootstrap.conf. Once you restart, you should see additional
TLS/SSL debug output in logs/nifi-bootstrap.conf.
For us to be able to offer further advice, you’ll need to provide more
information, like stacktraces from your logs, or the openssl output from
examining the certificates. Images do not come through on the list, so please
copy and paste text output instead. There are other possible explanations, such
as OS-limited cipher suites available, older browser versions, etc. but these
are much less common.
Add this line to bootstrap.conf:
java.arg.15=-Djavax.net.debug=ssl,handshake

Subject: How to run NiFi on HTTPS
Hi Team,
I have used tlstoolkit to create required files (nifi.properties,
keystore and truststore files) to run NiFi on HTTPS.
I also configured successfully and ran the NiFi service correctly which
show it is running on Https protocol.
But once I tried to see its UI I am facing following error on all
browsers (IE, Firefox and Chrome):
"Secure Connection Failed - An error occurred during a connection to
localhost:9090. Cannot communicate securely with peer: no common encryption
algorithm(s). Error code: SSL_ERROR_NO_CYPHER_OVERLAP"
[cid:[email protected]]
Could you please let me know how can I see NiFi UI in this case? I have
already tried all possible options (spread on internet) to get rid this issue
on browsers but no luc
