The only external dependence is blake3. ## Python installation ### from package ```bash # Set up a virtualenv. python3 -m venv venv source venv/bin/activate # Install from PyPI pip install hoshy ``` ### from source ```bash cd my-project git clone https://github.com/davips/hoshy ../hoshy pip install -e ../hoshy ``` ### Examples **Basic operations** <details> <p> ```python3 from hosh import Hash # Hashes can be multiplied. a = Hash(blob=b"Some large binary content...") b = Hash(blob=b"Some other binary content.
