Functions ¶
func EqualSum256 ¶
EqualSum256 compares BLAKE2s-256 hash. It returns if the sum matches to the hash of b.
func HMACEqualSum256 ¶
HMACEqualSum256 compares HMAC-BLAKE2s/256 hash. It returns if the sum matches to the hash of b.
func HMACSum256 ¶
HMACSum256 returns HMAC-BLAKE2s/256 hash. If the key length is grater than 32, it will be shorten to 32 bytes using sha256.Sum256. It uses golang.org/x/crypto/blake2s.New256.
Example ¶
package main
import (
"encoding/hex"
"fmt"
"github.com/aileron-projects/go/zcrypto/zblake2s"
)
func main() {
// Calculate HMAC-BLAKE2s-256 hash.
// Validation data can be generated with:
// - https://emn178.github.io/online-tools/blake2s/
// - https://toolkitbay.com/tkb/tool/BLAKE2s_256
key := []byte("secret-key")
sum := zblake2s.HMACSum256([]byte("Hello Go!"), key)
encoded := hex.EncodeToString(sum)
fmt.Println(len(sum), encoded)
fmt.Println("`Hello Go!` match?", zblake2s.HMACEqualSum256([]byte("Hello Go!"), key, sum))
fmt.Println("`Bye Go!` match?", zblake2s.HMACEqualSum256([]byte("Bye Go!"), key, sum))
}
Output: 32 3f010ec9bff3d4f9d0f6d020dcacfe9e2a2da397bce893b3bdfdb038d628875d `Hello Go!` match? true `Bye Go!` match? false
func Sum256 ¶
Sum256 returns BLAKE2s-256 hash. It uses golang.org/x/crypto/blake2s.New256.
Example ¶
package main
import (
"encoding/hex"
"fmt"
"github.com/aileron-projects/go/zcrypto/zblake2s"
)
func main() {
// Calculate BLAKE2s-256 hash.
// Validation data can be generated with:
// - echo -n "Hello Go!" | openssl dgst -blake2s256
sum := zblake2s.Sum256([]byte("Hello Go!"))
encoded := hex.EncodeToString(sum)
fmt.Println(len(sum), encoded)
fmt.Println("`Hello Go!` match?", zblake2s.EqualSum256([]byte("Hello Go!"), sum))
fmt.Println("`Bye Go!` match?", zblake2s.EqualSum256([]byte("Bye Go!"), sum))
}
Output: 32 0eb35c8350638fdb21de90833229bad5b19a0d3a9e61cc307c3c9b59859ea24c `Hello Go!` match? true `Bye Go!` match? false
