Hi!
I am using AWS KMS with a custom-managed key to sign and verify transactions using an asymmetric ECC_SECG_P256K1 key for Tron network blockchain.
I was able to sign and even verify the transaction through a AWS Lambda function, though what I need know is to transform the DER encoded signature into a hash and serialized tx compatible with the tron network.
I am perfectly able to retrieve R and S values of the signature but now I need to serialize it properly.
What is the proper way to accomplish that?
Thanks in advance!!
