The database stores encrypted passwords, which are annotated in document\structure.sql. If you need to customize other passwords, you can modify them here.

Encryption rules are in utility/helper.go.

func (u *utilHelper) PasswordBase58Hash(password string) (string, error) {
	data, err := u.Sha256OfShort(password)
	if err != nil {
		err = gerror.Wrap(err, "utilHelper PasswordBase58Hash Sha256OfShort error")
		return "", err
	}
	return u.Base58Encode(data), nil
}

HTTP API Support

/api Interface Permission Description

All /console/api/* interfaces require Bearer Token authentication. That is, each request header must include:

 Authorization: Bearer {sha256_of_password}

1. Add Short Link POST /api/url

Short Link Generation Code

Located in utility/helper.go.

func (u *utilHelper) GenerateShortLink(ctx context.Context, url string) (string, error) {
	var (
		err     error
		urlHash []byte
		logger  = u.Logger(ctx)
	)
	g.Log(logger).Debug(ctx, "utilHelper GenerateShortLink url:", url)
	if urlHash, err = u.Sha256OfShort(url); err != nil {
		err = gerror.Wrap(err, "utilHelper GenerateShortLink Sha256OfShort err")
		return "", err
	}
	// number := new(big.Int).SetBytes(urlHash).Uint64()
	// str := u.Base58Encode(gconv.Bytes(number))
    str := u.Base58Encode(urlHash)
	g.Log(logger).Debug(ctx, "utilHelper GenerateShortLink str:", str, " number:", number)
	return str[:8], nil
}
