Thank you for your post!

In order to create an EC certificate, you'll have to add the appropriate parameters to the key properties section, I'll share my JSON Body below to hopefully help resolve your issue.

EC JSON Body:

• Added the key property crv, which is the JsonWebKeyCurveName.
• Changed kty, the JsonWebKeyType to EC
• Changed the key_size to one of the supported sizes - 256, 384, 521 {
  "policy": {
  "key_props": {
  "exportable": true,
  "crv": "P-256",
  "kty": "EC",
  "key_size": 256,
  "reuse_key": false
  },
  "secret_props": {
  "contentType": "application/x-pkcs12"
  },
  "x509_props": {
  "subject": "CN=*.microsoft.com",
  "sans": {
  "dns_names": [
  "onedrive.microsoft.com",
  "xbox.microsoft.com"
  ]
  }
  },
  "issuer": {
  "name": "Self"
  }
  }
  }

If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
