crypto

crypto is the cryptographic package originally adapted for Tendermint's uses.

Importing it

To get the interfaces, import "github.com/gnolang/gno/libs/crypto"

For any specific algorithm, use its specific module e.g. import "github.com/gnolang/gno/libs/crypto/ed25519"

Functions

func AddressToBech32 

func AddressToBech32(addr Address) string

func CRandBytes 

func CRandBytes(numBytes int) []byte

This only uses the OS's randomness

func CRandHex 

func CRandHex(numDigits int) string

CRandHex returns a hex encoded string that's floor(numDigits/2) * 2 long.

Note: CRandHex(24) gives 96 bits of randomness that are usually strong enough for most purposes.

func CReader 

func CReader() io.Reader

Returns a crand.Reader.

func GetFromBech32 

func GetFromBech32(bech32str, prefix string) ([]byte, error)

GetFromBech32 decodes a bytestring from a Bech32 encoded string.

func PubKeyToBech32 

func PubKeyToBech32(pub PubKey) string

func Sha256 

func Sha256(bytes []byte) []byte
Example 
package main

import (
	"fmt"

	"github.com/gnolang/gno/tm2/pkg/crypto"
)

func main() {
	sum := crypto.Sha256([]byte("This is Tendermint"))
	fmt.Printf("%x\n", sum)
}

Output:
