----------------------------------

             Summary: Updating Encryption Algorithm failed for Apache Nifi 
"Decryption Failed with Algorithm [AES/GCM/NoPadding]"
                 Key: NIFI-11894
                 URL: https://issues.apache.org/jira/browse/NIFI-11894
             Project: Apache NiFi
          Issue Type: Bug
          Components: Security
    Affects Versions: 1.19.1
         Environment:  
            Reporter: Arsal Jalib


After upgrading Nifi, the following warning was logged when starting Nifi:

WARN [Flow Service Tasks Thread-2] d.o.a.n.s.u.c.NiFiLegacyCipherProvider 
Insecure Cipher Provider Algorithm [PBEWITHMD5AND256BITAES-CBC-OPENSSL] 
generate salt requested

This did not affect the function of Nifi. Its annoying So I followed the 
following resources, which seemed simple enough:

[https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html#updating-the-sensitive-properties-algorithm]
 
[https://exceptionfactory.com/posts/2021/07/29/deciphering-apache-nifi-component-property-encryption/#setting-the-sensitive-properties-algorithm]

However, after trying multiple paths, I always got the following error message 
when restarting Nifi:

Decryption Failed with Algorithm [AES/GCM/NoPadding] Caused by: 
javax.crypto.AEADBadTagException: mac check in GCM failed
