This package provides a few extra utilities for Python, like a "RateLimiter" class.
Project description
ExtraUtils
will provide a bunch of small functionalities to speedup development.
(In active development, so if you have any suggestions, to make other developers life easier, feel free to submit them.)
Latest addition
TimeBasedToken()
Generates a time-based token using two keys: a primary and a secondary. Ideal for encrypting traffic between devices or services without sharing the actual tokens.
How it works:
- Utilizes a unified timestamp, rounded to the nearest tenth of a second.
- Uses the primary token as is.
- Applies a transformation to the secondary token for added security.
Example:
primary = "1a2b3c4d5e6f7g8h9i0j1k2l3m4n5o6p"
secondary = "7q8r9s0t1u2v3w4x5y6z7a8b9c0d1e2f"
def main():
final_token = TimeBasedToken(primary, secondary)
print(final_token.regenerate())
enc = final_token.encrypt("Hello World, i am going to be encrypted and decrypted again. : )")
print(enc)
dec = final_token.decrypt(enc)
print(dec)
if __name__ == "__main__":
main()
RateLimiter()
Limits the rate of operations to prevent overloading. Configurable thresholds, decay rates, and behaviors on limit reaching.
Example
# A very simplified example
from ExtraUtils import RateLimiter
rate_limit = RateLimiter(10,15,5,1,True)
# threshold (10) -> increments before rate_limit.hit is set to True
# upperCap (15) -> the highest value the trigger counter will go
# decay_rate (5) -> the amount in triggers to be decremented each decay cycle
# decay_time (1) -> the time in seconds between each decay cycle
# extreme_case (True) -> if an exeption should be raised (if True) or just rate_limit.hit set to True (if False)
def rate_limit_test(i:int):
rate_limit.increment()
print(i,rate_limit.hit)
for i in range(20):
rate_limit_test(i)
# Output:
#0 False
#(1 to 8) False
#9 False
#Traceback (most recent call last):
# File "E:\Developement\RTS-Modules\ExtraUtils\showcase.py", line 14, in <module>
# rate_limit_test(i)
# File "E:\Developement\RTS-Modules\ExtraUtils\showcase.py", line 5, in rate_limit_test
# rate_limiter.increment()
# File "E:\Developement\RTS-Modules\ExtraUtils\ExtraUtils\RateLimit.py", line 30, in increment
# raise RateLimited()
#ExtraUtils.RateLimit.RateLimited: Rate limit reached
Aditional methods are:
RateLimiter().pause_decay()
RateLimiter().resume_decay()
