=Description=
Signs given data with ECC, returning generated signature and [[Certificates|certificate]].

Certificate is signed with ECDSA with SHA256 and holds an ECC public key.
Signed with the [[AMNet:GetDeviceCert|device certificate]].
ECC public key on certificate appears to be randomly generated on call(?).

Used by NIM to sign a message that's not sent over SOAP, however the device certificate, output signature and output certificate of the message are.
