!!! NOT SO SAFE! It is possible to reverse calculate source bytes from hash! !!!

Uses library random

Documentation can be found here.

Usage:

import egter

# ------- hashing -------

hash = egter.hash.EHash(b'some bytes', lenght=32, iterations=100)  # lenght - bytes count

print(hash) # equal to hexdigest method
# 90b0f287805156865bfebbf93eac3328ab0e9bcbb82dfcc9d5f88d6d41524766

print(hash.digest()) # bytes
# b'\x90\xb0\xf2\x87\x80QV\x86[\xfe\xbb\xf9>\xac3(\xab\x0e\x9b\xcb\xb8-\xfc\xc9\xd5\xf8\x8dmARGf'

print(hash.hexdigest())
# 90b0f287805156865bfebbf93eac3328ab0e9bcbb82dfcc9d5f88d6d41524766

print(hash.intdigest())

hash.update(b'add bytes to hash')
print(hash.hexdigest())

# set custom seed

# ------- encrypting -------
