This is a simple command-line tool written in Go that facilitates data signing and verification using RSA encryption. The tool leverages Protocol Buffers for message structure serialization. It accepts private and public key files, along with a file containing the data buffer to be signed or verified.

go build cmd/sproto.go
./sproto -sign -privateKey <private_key_file> -buffer <raw_buffer_file>
./sproto -verify -publicKey <public_key_file> -buffer <signed_buffer_file>
