Overview

Package sri provides the means to compute sub-resource-integrity sha sums for a list of files

Index

• func Hash(src io.Reader, dest io.Writer) error
• type Resource
  • func (r *Resource) MarshalJSON() ([]byte, error)
  • func (r *Resource) Reset()

Functions

func Hash

func Hash(src io.Reader, dest io.Writer) error

Hash computes the SHA256/384/512 sum for a list of files and writes each line as NDJSON to the given writer If an error occurs, Hash wont run to completion and the error will be returned immediately

Types

type Resource

type Resource struct {
	Path   string    `json:"path"`
	Sha256 hash.Hash `json:"sha_256"`
	Sha384 hash.Hash `json:"sha_384"`
	Sha512 hash.Hash `json:"sha_512"`
}

Resource is a named file with sub-resource-integrity hashes combined

func (*Resource) MarshalJSON

func (r *Resource) MarshalJSON() ([]byte, error)

MarshalJSON encodes the Resource into JSON, hex encoding the SHAsums

func (*Resource) Reset

func (r *Resource) Reset()

Reset resets the hashes of a Resource and zero-s out the filename
