I'm signing mails with the RSASSA-PSS (p1v2.1) certificate. When I click Details, it shows "Signature Algorithm: RSASSA-PSS". openssl x509 -text shows
Signature Algorithm: rsassaPss Hash Algorithm: sha256 Mask Algorithm: mgf1 with sha256
certutil -dump shows:
Now, whem I send my signed emails and click on Details in outlook, it shows "Signature Algorithm: RSA (2048)"
I'm using bouncycastle for signing and when I use "SHA256WithRSAEncryption" it works fine, but when I'm using "SHA256WithRSAAndMGF1" Signature, Outlook tells me "The digital signature on this item is Invalid or Not Trusted." and when I click details, I see "Signature Algorithm: RSA (2048)". Is p#1v2.1 still not supported by outlook/microsoft or am I just crazy?
