CoolTerm Checksum

[wellys]

Hi Roger,

CoolTerm is an outstanding product, particularly as it is multi-platform and free. Many thanks to those of us that need to recommend programs to students!

In my case, I teach a class on embedded programming and need to recommend CoolTerm to my students. They don't always follow very specific instructions such as "only download CoolTerm from the-meiers.org!!" And consequently, they download malware masquerading as your fine program.

Do you maintain a checksum list for your programs, such as SHA256? I've found the ability to checksum a program invaluable in reducing introducing malware.

Thanks,
Lief

Hi Lief,

I don't currently maintain a checksum list for any of my tools. I'll have to look into that.

Thanks, Roger for considering. This became a big deal when the instructor I'm working with accidentally downloaded the "wrong" version (wasn't on your site), and received malware instead of your great program. While I strongly advise only going to your site...not everyone listens to that. A second way of checking would be to add a checksum...

Mac and Linux are typically pretty easy, type the command in terminal then drag and drop the file:
openssl sha256 filename

Windows is a little different:
certutil -hashfile <file> SHA256

Or which is pretty slick
File Explorer Properties will provide the checksums as well

I found the Windows information here:

Thank you,
LIef

Thanks!

This should be pretty straightforward. I can add this to my build script.

Doing a quick test, these should be the checksums for the current release (v2.0.1) on my website:

Code: Select all

SHA2-256(CoolTermMac.dmg)= 7972a2cc93d1a4ae25c5018f81c951d21930032d9ea51fa1e680ea53c6c860fb
SHA2-256(CoolTermWin64Bit.zip)= 70bd44f868834b14c3fbf18eced7b3563ca44f69d3422009681affb1a5c8c641
SHA2-256(CoolTermWin32Bit.zip)= 0965d64e6f6f041b7c046f7b17aca61d005e41a8b83fc8d4befe000e87feeb35
SHA2-256(CoolTermWinARM64Bit.zip)= bdd59c77d567aea04474865c882b12b4518a8b75b4f88a4b41d5b41752dad428
SHA2-256(CoolTermLinux64Bit.zip)= 5b5c2d620d20e19f8e9aeef463ee2dcc23f7c843b6da2e36da05f045d6d668ce
SHA2-256(CoolTermLinux32Bit.zip)= fb4072c5a37744bd685e19d1fd63f649ac9824512cb1e860f24128dfc2172ab4
SHA2-256(CoolTermRaspberryPi.zip)= 258ab48d00698536585a2fcc1a0b3d5fb2ebb704776bf60d82d8c46ed4311c59
SHA2-256(CoolTermRaspberryPi64Bit.zip)= c10c0b9b8432c49a9e6ae77e68941036ea5e35a3dde6713b0fc3b74ba18c93ea

I can add a text file with these to my website.

Outstanding!

Many thanks, this will help me ensure the students (and professors) confirm they have the correct release.

I also added an entry on my site, recommending CoolTerm as THE solution.

Serial Applications for Embedded Development

Thank you!

I have now added a link to the text file with the SHA-256 checksums to my freeware site, just below all the CoolTerm download links. Going forward, all CoolTerm releases will have a corresponding text file with checksums available in the same place.

Thank you, I updated my site to the new location.

We're good!

Thank you on the partnership,
Lief
