# immudb_wrapper # immudb_wrapper
The wrapper around binary `immuclient` from project Codenotary. The wrapper around the SDK client `immudb-py` from project Codenotary, which expands the functionality of the original client with additional functions.
## Table of Contents
- [Requirements](#requirements)
- [Installation](#installation)
- [Usage](#usage)
- [Contribution](#contribution)
## Requirements
- python >= 3.7
- immudb-py >= 1.4.0
- GitPython >= 3.1.20
## Installation
You can easily install `immudb_wrapper` into your environment with the following command:
```
pip install git+https://git.almalinux.org/danfimov/immudb_wrapper.git@<tag|branch>#egg=immudb_wrapper
```
To run the `immudb` instance locally, you can use the options from `immudb` [documentation](https://docs.immudb.io/master/running/download.html).
If you want to use the `immudb` in `docker-compose.yml`, you can add the following in your compose file:
```
immudb:
image: codenotary/immudb:latest
ports:
- 3322:3322
- 9497:9497
volumes:
- "../volumes/immudb/data:/var/lib/immudb"
- "../volumes/immudb/config:/etc/immudb"
- "../volumes/immudb/logs:/var/log/immudb"
```
## Usage
### Client initialization
```python3
client = ImmudbWrapper(
username="user",
password="password",
database="database",
)
```
### File notarization
This method calculates the file hash and file size and inserts them with the user's metadata (if provided), into the database.
```python3
response = client.notarize_file(
"./hello_world.sh",
user_metadata={
"foo": "bar",
},
)
print(response)
{
'id': 1,
'key': '4db5767d4bf4221a5656b163ef1bae833095255f80d1ad5be21dfef84caf4126',
'value': {
'Name': 'hello_world.sh',
'Kind': 'file',
'Size': '2.62 KB',
'Hash': '4db5767d4bf4221a5656b163ef1bae833095255f80d1ad5be21dfef84caf4126',
'Metadata': {
'sbom_api_ver': '0.2',
'foo': 'bar',
},
},
'timestamp': 1690794033,
'verified': True,
'refkey': None,
'revision': 1,
}
```
### Git repo notarization
This method extracts the git metadata from a provided git directory, calculates the hash of the extracted metadata and inserts that metadata with the user's metadata (if provided), into the database. Falls with a `InvalidGitRepositoryError` when accepting non-git directories.
```python3
response = client.notarize_git_repo(
"./immudb_wrapper/",
user_metadata={
"foo": "bar",
},
)
print(response)
{
'id': 2,
'key': 'a87f7a948900e04812c095fb457e994926fc28c2a789471521fcc076cc4d8658',

},

}
```
### Git repo authentication
This method extracts the git metadata from a provided git directory, calculates the hash of the extracted metadata, and looks up the metadata of that hash in the database. Returns a dict with an error if metadata doesn't exist in the database.
```python3
response = client.authenticate_git_repo("./immudb_wrapper/")
print(response)
{
'id': 2,
'key': 'a87f7a948900e04812c095fb457e994926fc28c2a789471521fcc076cc4d8658',
