Frequently asked questions
Is keytool.exe safe?
keytool.exe is a normal part of Java 8 when it sits in the program's install folder and carries the publisher's digital signature. A file with the same name in another folder can be something else: check its signature and hash.
Where is keytool.exe located?
By default the installer puts it in %ProgramFiles%/Eclipse Adoptium/jdk-8.0.482.8-hotspot. The folder can be changed during installation.
How do I remove keytool.exe?
Uninstall Java 8 through Settings → Apps or with winget; the uninstaller removes keytool.exe with it. Deleting the file alone leaves the rest of the program behind.
