The Azure Key Vault service returns ECDSA signatures in "raw" format (the same used by Windows bcrypt and ncrypt APIs). The Java Crypto provider (SunEC) which the local ECKey implementation uses ASN.1 DER format. Because of this signatures created by the service cannot be verified using the local ECKey and vice versa. The ECKey implementation must be updated to issue and accept signatures in "raw" format.
