KVS

Key Value Services is a cli tools that help to you create your Key-Value store services.

Motivation

I want to create a content sharing tool that is managed by only one person and readable by many people in a secure network environment, so that I can use some common content in the terminal.

Install

bash cargo install key_value_service

Warning

This project is still in the early stage of development and is only used as a development tool. Do not use it for data storage in the production environment. If you have this requirement, I recommend that you use redis. Some APIs will undergo destructive changes without notice.

Usage

  1. Start kvs in your server

```bash

kvs start 2022-03-18T15:59:26.503861Z INFO starting with 0.0.0.0:8888 successfully! ```

  1. Login the kvs services from client ```bash

    kvs -r 0.0.0.0:8888 login 2022-03-18T16:05:05.022305Z INFO Token: FAAAAAAAAACUH40t6d+A9jzhexGHktUINvWwL317xp1/AQAAFAAAAAAAAACrtlLcjeSqhMZCj5rnNn2hkf0K/w== 2022-03-18T16:05:05.022393Z INFO Save Token file to: .kvs/token ```

  2. Create a private key value ```

    kvs create foo "hello world" ```

default, kvs will encrypt the value use your priv_key in local. Remote just judge the key's owner. The decryption process needs to be completed by the client itself.

  1. Read a key ```

    kvs read foo hello world ```

  2. Create a public key value

```

kvs create priv_foo "priv hello world" -p ```

If you just do. kvs will send the value and save value as plaintext in remote.

  1. Read a private key ```

    kvs cat priv_foo priv hello world ```

  2. Delete a Key ```

    kvs delete priv_foo ```

You just can delete key that owner is you.

  1. Update a Key kvs create priv_foo "this is change data" kvs read priv_foo this is change data

  2. show remote info ```

    kvs remote 0.1.3 ```

  3. show local info ```

    kvs local scope: 0x4d7153428dd617a410f114468d212a9cd1b7ccd0 pub: MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQD9qWAweIhnLfBdjYj8oty1z2FYycQ8qhebrDLCQBJPTF1IfV282WCHET7Fsjd1C9+XMbW2xT0f73cZgSExgILeGjZFlx9gEf5VVJyBezfQ6yU2V9Emo58zRh6fjfoBGUsXmVIJIGCpnVjHg/ECEVKuDVQ3h0SEHrdxE98bSl9RIQIDAQAB ```

  4. Read other scope key ```

    kvs read -s 0xad359ae3e478342ed2b5512ed7ff4ebb3ceb2dd test_pub pub content ```

  5. Restart the kvs Server ```

    kvs restart ```

  6. Stop the kvs Server ```

    kvs stop ```

  7. remove all keys ```

    kvs list | awk -F '\t' '{print "kvs delete " $2}' | bash ```

    Examples

Case1 sync info in one team

Your team have a big list of resource id.

```bash

importantresourceid.txt

... A7EB0B7B-3E27-4531-B239-750300EE8D0C B9164246-49E3-45F1-A8CE-D871CEBE3971 92312D9B-B2D8-4A92-B7B5-9A5491FF9BEC 8E1B24ED-0023-45E0-BF34-1548C8D8884D ... ```

Some times, the team member need create the url by the big list.

```bash

importantresourceurls.txt

... http://xxx.xxx.xxx.xxx/app/goods/A7EB0B7B-3E27-4531-B239-750300EE8D0C http://xxx.xxx.xxx.xxx/app/goods/B9164246-49E3-45F1-A8CE-D871CEBE3971 http://xxx.xxx.xxx.xxx/app/goods/92312D9B-B2D8-4A92-B7B5-9A5491FF9BEC http://xxx.xxx.xxx.xxx/app/goods/8E1B24ED-0023-45E0-BF34-1548C8D8884D ... ```

Let's assume we have written a command line tool named transform to handle this case.

cat important_resource_urls.txt | transform

The question is, how do I share important_resource_urls.txt with other team members.

Granted, there are many ways to share it. But you can fast finish it if you use the kvs.

```bash

create the key

kvs create importantresourceurls -f importantresourceurls.txt

and then, other team member can use it.

kvs read importantresourceurls | transform ```

Case1 sync info in public

bash curl https://xxx/a.json | json "important" | kvs create important -f -p kvs read important -s your_scope

Case2 prove yourself

You can tail your pub key to some website.

```

kvs local scope: 0x4d7153428dd617a410f114468d212a9cd1b7ccd0 pub: MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQD9qWAweIhnLfBdjYj8oty1z2FYycQ8qhebrDLCQBJPTF1IfV282WCHET7Fsjd1C9+XMbW2xT0f73cZgSExgILeGjZFlx9gEf5VVJyBezfQ6yU2V9Emo58zRh6fjfoBGUsXmVIJIGCpnVjHg/ECEVKuDVQ3h0SEHrdxE98bSl9RIQIDAQAB ```

Website will tail you a cipher text.

website: (your pub key) + (random value) -> (cipher text)

Now you can use kvs de command to decrypt the (cipher text)

```

kvs de (cipher text) (random value) ```

Tail the (random value) to website. you will prove yourself to website.

Community * [x] add sync command to sync all file in one directory and use the relative directory as key. * [x] add list command to list all key meta in your scope. * [x] add restart command to restart the server. * [x] add stop command to stop the server. * [x] add set and get command to config some value in client local. * [x] add set command to set the config in client local. * [x] add --file option in create and upload command. * [x] add the same option in sync command look like create update. * [x] append show public key in kvs local. * [x] add kvs de command to decrypt some content. use local private key by default. * [x] add kvs en command to encrypt some content. use local public key by default.

Commercial * [ ] add the p2p in share key progress. * [ ] Build a free central storage node. * [ ] add upgrade command to sync the remote kvs cli to client local.
