Example(用例)

It's very unlikely, but possible, that a given index does not produce a valid private key. Error checking is skipped in this example for brevity but should be handled in real code. In such a case, a ErrInvalidPrivateKey is returned.

ErrInvalidPrivateKey should be handled by trying the next index for a child key.

Any valid private key will have a valid public key so that Key.PublicKey() method never returns an error.

package main

import (
  "github.com/huangkaiqiao/go/crypto"
  "fmt"
)

func main() {
    // 使用随机 key 生成 cipher 对象
    c, _ := NewCipher(RandomKey(), nil)
    inpath := "plaintext.txt"
    // os.Remove(inpath + ".mn1")
    // os.Remove(inpath + ".out")
    outpath, _ := c.EncryptFile(inpath, "")
    plainpath, _ := c.DecryptFile(outpath, "")
	// fmt.Println(plainpath)
	expected, _ := Sha256File(inpath)
	result, _ := Sha256File(plainpath)
	assert.Equal(t, expected, result)
}

package main

import (
  "github.com/huangkaiqiao/go/mnemonic"
  "fmt"
)

func main() {
	// 获取助记词
  mnemonic := mnemonic.NewMnemonic()
  fmt.Println(mnemonic)

  // 生成 filecoin 地址
  address := mnemonic.FromMnemonic(mnemonic)
  fmt.Println(address)
}
