SignatureDescription could not be created for the signature algorithm supplied when using ECDSA algorithm

[pauloortins]

I'm integrating SecureAuth as an IDP using SAML to my Azure B2C and SecureAuth by default uses ECDSA as the encryption algorithm.

<ds:SignatureMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#ecdsa-sha256"/>

When I integrate it the Azure B2C throws the following error:

"SignatureDescription could not be created for the signature algorithm supplied."

The only ways I'm able to make it work is:

1. Force SecureAuth to use RSA instead.

2. Disable the encryption by doing:

false false

Is there an 3rd way when the Azure B2C can support the ECDSA algorithm?

AAD B2C doesn’t support ECDSA.

Thank you for your answer!

Is there any place where Microsoft added it to their docs?
