Description
Wraps AMPXI:Sign.
Signs given data with ECC, returning generated signature and certificate.
Certificate is signed with ECDSA with SHA256 and holds an ECC public key. Signed with the 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.
