Mono version 3.0.12, built from the tarball, fails to import certs with the following exception:
Error: System.Security.Cryptography.CryptographicException: Unsupported hash algorithm: 1.2.840.10045.4.3.3
at Mono.Security.Cryptography.PKCS1.HashNameFromOid (System.String oid)
Full excpetion at http://cl.ly/image/2V2D411Q0V0O, but too hard to retype the whole thing. :)
1.2.840.10045.4.3.3 uses ECC which Mono does not support (it's sha384ECDSA).
The Hash property used to return null but now throws an exception (since recent refactoring).
It might be better to ignore/report this inside mozroot, before we silently ignored that CA.
Fixed in 85cb07992dcab999cd0503b5f82fe6f3462e1366
We won't throw, like before, to ensure we do not regress any other code/tool (beside mozroots). Installing a newer Mono.Security.dll will solve the issue in existing systems.
