¶
This code can do inline sha256 calculations godoc:
package main
import (
"github.com/Harnish/sha256proxy"
"fmt"
"io"
"os"
)
func main() {
shain := shaproxy.New()
f, err := os.Open("myfile.txt")
if err != nil {
fmt.Println(err)
}
fo, err := os.Create("junk.file")
if err != nil {
fmt.Println(err)
}
reader := shain.NewProxyReader(f)
io.Copy(fo, reader)
shain.Finish()
fmt.Println(shain.SumHex())
}
I used gopkg.in/cheggaaa/pb.v1 as the example for this as I was trying to add progress to my app that sha256s the file before and after the transaction.

Overview ¶
Package shaproxy provides a stream reader object to allow calculating mulitple sha256s inline. This is useful when capturing the sha256 prior to transformation of data and after.

Types ¶
type ShaProxy ¶
type ShaProxy struct {
// ShaHash is the Hash object that is added to as the stream is read
ShaHash hash.Hash
// contains filtered or unexported fields
}
func (*ShaProxy) Finish ¶
func (me *ShaProxy) Finish()
This executes the final calculation of the sha256 sum and sets the values.
func (*ShaProxy) NewProxyReader ¶
This takes an io.Reader and returns an io.Reader. It does not modify the data in the stream but adds to the object's hash.
