TS9521C certificate generation

[dgrable]

After completing the process of generating a certificate, the certificate gets downloaded as a .bin file(tls_download_csr.bin) which I cannot open/read.  I need it to be in a base 64 format.  Is there some sort of software that can read the bin file so that I can copy/paste the contents?  Thanks.

Hi, dgrable!

So that the Community can help you better, we need to know exactly which operating system is running on your computer (i.e. Windows or macOS, and which version thereof) and which apps you're trying to print from. That, and any other details you'd like to give will help the Community better understand your issue!

If this is a time-sensitive matter, click HERE search our knowledge base or find additional support options HERE.

Thanks and have a great day!

I'm running a Windows 10 PC.  The printer is installed on a Server 2019 print server.  Printing is not the issue, I have it working on multiple PC's through group policy.  It's the format of the certificate that I generate that's the issue.  It's not what I would call the norm.

Hello, dgrable. I had the same problem with my Canon TM-305.

The solution is:

1. Create tls_download_csr.bin via your Canon web-ui

2. Convert your tls_download_csr.bin into Base64-format using online-converter (for example: https://base64.guru/converter/encode/file

3. Get your Base64-format text to your CA Server (for example: microsoft certsrv)

4. Add SAN (Subject Alternative Name) to your CSR (The connection will be unsecure without it). If you use microsoft CA certsrv via web, this will help you: https://learn.microsoft.com/en-us/troubleshoot/windows-server/certificates-and-public-key-infrastruc...

5. Get your der-certificate file

6. Upload your der-certificate to your Canon Printer, Select DER, mark checkbox "Use The Private key stored on the printer for generating CSR"

After that your HTTPS-connection to your printer's WEB-UI will be secured.
