Hello,

I've been told that someone on this forum will be able to help with this issue.

I noticed a problem with the MacOS JDK 8 tar.gz file (jdk8u322-b06) on Temurin - I get an incorrect checksum for SHA256.

Download URL: adoptium.net/temurin/releases/?variant=openjdk8&jvmVariant=hotspot

Checksum on adoptium: 96a3124bf0f5ca777954239893cc89ea34c4bc9a9b7c1559aa2c69baa0ee84e3

SHA265 Checksum from downloaded file: bd8883b6b90e01b05c58b5eb263b0566a6c2f652ae444e4fcb496937218a1281

This issue has been ongoing for some time. Can someone please check?

Thank you for your help!

How are you computing your own checksum? It matches for me.

Thanks for your reply!

I calculated the SHA256 checksum with both these online checksum calculators:
md5file.com/calculator
appdevtools.com/checksum-calculator

It always comes out as bd8883b6b90e01b05c58b5eb263b0566a6c2f652ae444e4fcb496937218a1281

I have tried downloading the file again, but it's still the same.

On Adoptium it says that the checksum is 96a3124bf0f5ca777954239893cc89ea34c4bc9a9b7c1559aa2c69baa0ee84e3

I do not have this problem with other files, only the tar.gz file for jdk8u322-b06.

I tried downloading the .pkg-file and using the same calculators, the checksum comes out as correct.
Unfortunately I need the tar.gz file instead, since I do not plan on installing the whole package.

Actually, I have the same problem with the tar.gz-file for JDK 11 (macOS x64)
name on Temurin: jdk-11.0.14.1+1

So it seems to be a broader issue with my checksum calculation of tar.gz-files or at least two of the tar.gz files on Adoptium.
Can you give me any pointers as to what I'm doing wrong?

Ok, I have found the common denominator - I used Safari to download and somehow that browser messes up the checksum of tar.gz files.
I now downloaded with Chrome and the checksum is fine.
Thanks again and sorry for the bother!

"shasum -a 256 -b ~/Downloads/OpenJDK8U-jdk_x64_mac_hotspot_8u322b06.tar.gz " shows the correct checksum for me. (Actually -b doesn't even seem to be necessary.)

appdevtools.com gives the same result for me. (But I wouldn't rely on an external site to check a checksum.)

So, if you are consistently getting mismatching checksums for these files, maybe some corporate proxy or virus scanner interferes? Either inbound or outbound, since you uploaded the file to an external website.

Try verifying the checksum locally.
