I have a raw signature in DER format which is signed externally by HSM by secp256k1. How do I convert it to the format [v,r,s] for Klaytn? I tried and found out it is similar to EIP-155 which the value of [v] is the chaid-id*2+35+orig.v.slice(64,)
. If [v]
is incorrect, the system will show Invalid chainId
error message so I think value of [v]
might be correct. However, I am not sure how to compose the value of [r,s]
since I have retrieved them by [orig.r.slice(0,32), orig.s.slice(32,64)]
but got an error of Returned error: invalid transaction v, r, s values of the sender
.
Any detailed explanation for converting the signature from DER format to [v,r,s]? I have read Klaytn doc and only RLP encoding related functions are found from the website.
