3.10.2. HSM_MANAGER.sign(data, key)

This method uses the key provided to generate an ECDSA signature over the provided data.

The return value of this method is a common_util.BYTE_ARRAY() containing the R and S values of the signature concatenated. PACSign only signs hashes, so the length of the data to be signed will be a fixed-length 32 byte array.
