钱包规范

Version 1.0.0

钱包规范描述了钱包数据结构及导出数字身份或资产账号二维码的数据结构。

1. 钱包文件结构

钱包文件数据以json格式存储，文件名后缀并无要求，钱包文件数据结构如下:

{
  "name": "MyWallet",
  "version": "1.0",
  "scrypt": {},
  "defaultOntid": "did:ont:TJNxJe2Ty8eSCjCDxDPwiS78NRAn8XPTFL",
  "defaultAccountAddress": "TJNxJe2Ty8eSCjCDxDPwiS78NRAn8XPTFL",
  "createTime": "2018-03-14T03:12:30.862Z",
  "identities": [],
  "accounts": [],
  "extra": null
}

参数描述：

name 钱包名.

version 钱包版本号.

scrypt SCrypt算法参数.

defaultOntid 钱包中的默认Ontid.

defaultAccountAddress 钱包中默认账户地址.

createTime 钱包创建时间.

identities 身份列表.

accounts 账户列表.

extra 备用参数.

一个真实的钱包数据如下:

{
	"name": "mickey",
	"defaultOntid": "",
	"defaultAccountAddress": "",
	"createTime": "2018-06-30T08:52:01.519Z",

		"enc-alg": "aes-256-gcm",
		"salt": "u+SiqpRk17b0vIPesh4xXA==",
		"isDefault": false,
		"publicKey": "037fb6dfc9420e1d8275d9133d6d69fe64e8e3567241e7583234b9efa8b2ce7ae1",
		"signatureScheme": "SHA256withECDSA"
	}],
	"extra": null
}

1.1 Scrypt参数
