# Memoria
*Memoria* is a Python library for hashing and caching.
## Installation
```shell
pip install memoria
```
## Benefits of Memoria
### Consistency
Unfortunately the built-in *hash* method is not consistent.
For example if you hash a string in two different Python sessions,
*e.g.*, `hash('hello world!')`, you may get different results, *e.g.*, `-69600567246316219` or
`-8701498716516122875`. However, Memoria is consistent, *e.g.*,
`memoria.hash('hello world!')` produces `PwDVM4wattDXKR1HUtszcPP5BHTUVTYQ5X0cO51yAn4=`.
We should credit the built-in library [hashlib](https://docs.python.org/3/library/hashlib.html) of course.
### Hashing Unhashable Types
Memoria can hash virtually anything. If you use the built-in
*hash* method `hash(dict())` or `hash(list())` you will get an error:
`TypeError: unhashable type: 'dict'` but **Memoria** can even hash
*unhashable* types by converting them into a hashable type and
hashing the result. To make sure that the hash is still different between
the original type and the hashable representation, Memoria takes some
additional measures.
## Usage
```python
import memoria
# hashing a python object
memoria.hash(123)
# >>> 'zi+wk24s9wwA/UiNRKbjeu6JfDi78yCj7yVL87sS0Ko='
# base is 64 by default but 32 can also be used.
# base 64 should not be used in the file-system, e.g., file names, because it has inadmissible characters.
memoria.hash(123, base=32)
# >>> 'PONR14RE5JRGO07T926K99N3FBN8IV1ONFPI18VF4L5V7EOIQ2L0----'
# dictionaries are unhashable but Memoria can hash them
memoria.hash({'name': 'John', 'age': 24})
# >>> 'ioCMz5B8pcdk2CxcbIX/3n3qnQRn/yv9/zvC5Wc0YlU='
