hash -- Calculating Hash Value

Install

$ go get github.com/spiegel-im-spiegel/hash

Installing by dep.

$ dep ensure -add github.com/spiegel-im-spiegel/hash

Usage

v, err := hash.Value(bytes.NewBuffer([]byte("")), crypto.SHA1)
if err != nil {
    return
}
fmt.Printf("%x\n", v)
// Output:
// da39a3ee5e6b4b0d3255bfef95601890afd80709

v, err := hash.ValueFromBytes([]byte(""), crypto.SHA1)
if err != nil {
    return
}
fmt.Printf("%x\n", v)
// Output:
// da39a3ee5e6b4b0d3255bfef95601890afd80709
