# Neo Toolbox

Small toolkit for interacting with the Neo N3 blockchain.

### Available tools

1. [Data Transformation](#data_transformation)
2. [Create Owner Bytes](#create_owner_bytes)
3. [Create Update Invocation File](#create_update_invocation_file)



#### <a name="data_transformation"></a>Data Transformation

Lets you convert between wallet hashes and addresses.

##### Example

```python
from neo_toolbox.data_transformation import encode_hash, decode_address

# Encode a wallet hash
original_hash_hex = 'a7271ccc82bb311db369719d1868e6ac19ece31f'
address = encode_hash(original_hash_hex)
print(address)
# Outputs: 'NNpbB25aNMY2pD5JkWeAEbsNfp7C3GoZF1'

# Decode a wallet address
original_address = 'NNpbB25aNMY2pD5JkWeAEbsNfp7C3GoZF1'
hash_hex = decode_address(original_address)
print(hash_hex)
# Outputs: 'a7271ccc82bb311db369719d1868e6ac19ece31f'
```


#### <a name="create_owner_bytes"></a>Create Owner Bytes

This helper function lets you convert a N3 wallet address to an python variable that can be used
in your smart contract to verify the owner of the contract. This is very useful to add admin
functionality to your smart contract.

##### Example

```python
from neo_toolbox.create_owner_bytes import create_owner_bytes

original_address = 'NNpbB25aNMY2pD5JkWeAEbsNfp7C3GoZF1'
code_snippet = create_owner_bytes(original_address)
print(code_snippet)
# Outputs: 'OWNER = UInt160(b"\x1f\xe3\xec\x19\xac\xe6h\x18\x9dqi\xb3\x1d1\xbb\x82\xcc\x1c'\xa7")'
```

#### <a name="create_update_invocation_file"></a>Create Update Invocation File

This helper function lets you create a [Neo Express](https://github.com/neo-project/neo-express)
invocation file that can be used to update a smart contract.

##### Example

```python
from neo_toolbox.create_update_invocation_file import create_update_invocation_file

nef_file = 'path/to/sample_contract.nef'
manifest_file = 'path/to/sample_contract.manifest.json'
template = create_update_invocation_file('your_contract_name', nef_file, manifest_file, operation='my_custom_update')
print(template)
# Outputs a JSON string: '[{"contract": ...'
```
