Functions

func Digest

func Digest(src []byte) ([]byte, error)

Digest calculates the SHA-256 digest and returns the resulting slice.

Example

package main

import (
	"fmt"

	"gopkg.in/goyy/goyy.v0/util/crypto/sha256"
)

func main() {
	dst, _ := sha256.Digest([]byte("goyy"))
	fmt.Println(fmt.Sprintf("%x", dst))

}

Output:

294d5a5ab822caec5c8ef8db496a44a5f185d83feb0699ab69e79b51166a1116

func DigestHex

func DigestHex(src string) (string, error)

DigestHex calculates the SHA-256 digest and returns the resulting hex string.

Example

package main

import (
	"fmt"

	"gopkg.in/goyy/goyy.v0/util/crypto/sha256"
)

func main() {
	dst, _ := sha256.DigestHex("goyy")
	fmt.Println(dst)

}

Output:

294d5a5ab822caec5c8ef8db496a44a5f185d83feb0699ab69e79b51166a1116

func DigestSum

func DigestSum(src, sum []byte) (dst []byte, err error)

DigestSum calculates the SHA-256 digest to sum and returns the resulting slice.

Example

package main

import (
	"fmt"

	"gopkg.in/goyy/goyy.v0/util/crypto/sha256"
)

func main() {
	dst, _ := sha256.DigestSum([]byte("goyy"), []byte("goyy:"))
	fmt.Println(fmt.Sprintf("%x", dst))

}

Output:

func DigestSumHex

func DigestSumHex(src, sum string) (dst string, err error)

DigestSumHex calculates the SHA-256 digest to sum and returns the resulting hex string.

Example

package main

import (
	"fmt"

	"gopkg.in/goyy/goyy.v0/util/crypto/sha256"
)

func main() {
	dst, _ := sha256.DigestSumHex("goyy", "goyy:")
	fmt.Println(dst)

}

Output:

676f79793a294d5a5ab822caec5c8ef8db496a44a5f185d83feb0699ab69e79b51166a1116
