Asherah envelope encryption and key rotation library

This is a wrapper of the Asherah Go implementation using the Cobhan FFI library

Usage

Example code:

from asherah import Asherah, AsherahConfig

config = AsherahConfig(
    kms='static',
    metastore='memory',
    service_name='TestService',
    product_id='TestProduct',
    verbose=True,
    enable_session_caching=True
)
crypt = Asherah()
crypt.setup(config)

data = b"mysecretdata"

encrypted = crypt.encrypt("partition", data)
print(encrypted)

decrypted = crypt.decrypt("partition", encrypted)
print(decrypted)

Benchmarking

Included is a benchmark.py script that will give you an idea of the execution speeds you can see from this library. Our goal is to make this as performant as possible, as demonstrated by this example output:

> python benchmark.py
