Hi All,

I am working on azure function and I have to read the .pfx certificate file. Can some one please guide where to store the .pfx certificate and use in azure function?

I tried the below approaches but always I get the error "specified file could not find":
1) Tried uploading the file in KeyValut certificate, It restrict me to upload the .pfx file, it gives the error "Unsupported key size (1024). Supported sizes are [2048, 3072, 4096]".
2) Uploaded the file in AzureBlob and read the file by url in azure function, unfortunately it doesn't help.
3)Reading the file from kudo bin(azure function) doesnt work

 X509Certificate2 cert = new X509Certificate2("certificatepath", "password");


Thanks
Hemant

    No,

    I had that folder in my solution itself. Refer below screenshot. By the way, it does not have to be a same folder structure as long as you provide the correct path while reading the certificate file.

    Hope this helps.

    Thanks Ravi for your reply.

    Did you create a folder "Resources" in kudo?

    I can not find the folder 'Resources' in kudo when I open it so I created folder manually in kudo but whenever I build my Azure Function and publish from visual studio , the folder gets removed.

    Regards

    Hi,

    I worked on the similar scenario where I wanted run my code recusivly. I used Azure function app and configure a timer trigger. The App was console application which uses the Certificate.  Whithin the console app, I retrieved the certificate path from config. The actual certificate file I stored in in Kudo under the Resource folder and the updated the path in config like this-

    <add key="SigningCertificate" value="D:\home\site\wwwroot\MyAzureFunction\Resources\cert\mycertificatefile.pfx" />

    I referred the below blog for this-

    Hopefully this will help you as well.
