Generating the SHA hash of a string using golang

Question

An example :

import (
    "crypto/sha1"
    "encoding/base64"
)

func (ms *MapServer) storee(bv []byte) {
    hasher := sha1.New()
    hasher.Write(bv)
    sha := base64.URLEncoding.EncodeToString(hasher.Sum(nil))
        ...
}

In this example I make a sha from a byte array. You can get the byte array using

bv := []byte(myPassword)

Of course you don’t need to encode it in base64 if you don’t have to : you may use the raw byte array returned by the Sum function.

There seems to be some little confusion in comments below. So let’s clarify for next users the best practices on conversions to strings:

you never store a SHA as a string in a database, but as raw bytes
when you want to display a SHA to a user, a common way is Hexadecimal
when you want a string representation because it must fit in an URL or in a filename, the usual solution is Base64, which is more compact
