# OCMF-go
OCMF-go is an implementation of the Open Charge Metering Format (OCMF) in Go. It provides a simple library for
generating and parsing OCMF messages. The provided message builder generates OCMF-compatible messages and signs the data
with the provided private key, desired algorithm and encoding, so you don't have to.
## Installation
```shell
go get github.com/ChargePi/ocmf-go
```
## Usage
```go
package main
import (
"fmt"
ocmf_go "github.com/ChargePi/ocmf-go"
"github.com/lorenzodonini/ocpp-go/ocpp1.6/types"
)
func main() {
// Generate a new message builder
builder := ocmf_go.NewBuilder()
// Set the signature algorithm
builder.SetSignatureAlgorithm(ocmf_go.SignatureAlgorithmECDSAsecp256r1Sha256)
// Set the signature encoding
builder.SetSignatureEncoding(ocmf_go.SignatureEncodingBase64)
// ... set the desired fields
message, err := builder.Build()
if err != nil {
fmt.Println(err)
}
// Create a MeterValue message with the generated message as value
meterValueExample := types.MeterValue{
SampledValue: []types.SampledValue{
{
Value: message,
Format: types.ValueFormatSignedData,
},
},
}
// Send the message via OCPP 1.5/1.6.
}
```
