Add more description on password handling into the keytool man page. A link to the man page is now added to the keytool help screen.
When keytool output is redirected into a file or file, a warning is shown: $ keytool -genkeypair | type Warning: password will be echoed because output is redirected. Enter keystore password: password Warning: password will be echoed because output is redirected. Re-enter new password: A new manual test is added. Sorry we cannot suppress password echoing in this case at the moment because `System.console()` is not available. ------------- Commit messages: - tests - show warning when echo is on - link and man page changes Changes: https://git.openjdk.org/jdk/pull/24805/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=24805&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8354469 Stats: 219 lines in 11 files changed: 166 ins; 18 del; 35 mod Patch: https://git.openjdk.org/jdk/pull/24805.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/24805/head:pull/24805 PR: https://git.openjdk.org/jdk/pull/24805
