[jira] [Commented] (NIFI-3063) TLS Toolkit ignores provided
password if longer than 7 characters and switches to auto-generated 7
character password
[ https://issues.apache.org/jira/browse/NIFI-3063?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17040857#comment-17040857 ]

---------------------------------------
Hi [~alopresto],
I was going through the ticket and found that even when a JCE policy is Unlimited, we get the password to be random. I believe the bug is from the TlsToolkitStandaloneCommandLine class where theΒ getPasswords method parses the arguments given in a wrong way. So I would check further. I checked for nifi-1.12 . This appears to be an issue with -P parameter.
However, when the following command is run it doens't have the randomness :
./bin/tls-toolkit.sh standalone -C 'CN=test' -B password

> URL: https://issues.apache.org/jira/browse/NIFI-3063
> Project: Apache NiFi
> Issue Type: Bug
> Components: Tools and Build
> Affects Versions: 1.1.0
> Reporter: Andy LoPresto
> Assignee: karthik kadajji
> Priority: Critical
> Labels: pkcs12, security, tls-toolkit

> Because of work done for [NIFI-2943], the TLS Toolkit cannot accept a password longer than 7 characters for a PKCS12 keystore if the JCE unlimited strength cryptographic jurisdiction policies are not installed. While the tool correctly warns about this, it quietly switches from the provided password to an auto-generated 7 character password. There is a small log message saying the password has been switched to an auto-generated, reduced password, but this is easy to miss and surprising functionality. While not as secure, truncating the provided password to 7 characters is less likely to cause confusion for users.
