Types

type SHA256Checksum

type SHA256Checksum string

SHA256Checksum is a 64 character string representing a SHA256 hash TODO: How to assign a `string` to `[64]string` ? Goal: Set SHA256Checksum as the return type for GenerateCheckSum(), but make sure that the length is locked in at the specific character length for our chosen file hash. type SHA256Checksum [64]string

func GenerateCheckSum

func GenerateCheckSum(file string) (SHA256Checksum, error)

GenerateCheckSum returns a SHA256 hash as the checksum generated from a provided fully-qualified path to a file.

func (SHA256Checksum) String

func (cs SHA256Checksum) String() string

func (SHA256Checksum) Verify

func (cs SHA256Checksum) Verify(file string) error

Verify takes a path to a file, generates a SHA256 checksum from the file and compares against the checksum value already present
