hashed 2.2.0

Provides secured hashes for given data

Python Package Link:

A simple SHA-2 implementation in python which gives hash for string or a file. Suported hashing algorithms: SHA56, SHA512

CLI Tool Usage

• Example

python hashed/cli.py -s "Hello World!!" --sha256

Hash:  096c0a72c31f9a2d65126d8e8a401a2ab2f2e21d0a282a6ffe6642bbef65ffd9

• For help

usage: Hashing Library [-h] [--sha256] [--sha512] [-s STRING] [-f FILE] [-fb BINARY_FILE] [-t] [-p] [-b]

Provides secured hashes for given data

options:
  -h, --help            show this help message and exit
  --sha256              Generates SHA-256 for given input (default: False)
  --sha512              Generates SHA-512 for given input (default: False)
  -s STRING, --string STRING
                        String to be hashed (default: None)
  -f FILE, --file FILE  File to be hashed (default: None)
  -fb BINARY_FILE, --binary_file BINARY_FILE
                        Binary file to be hashed (default: None)
  -t, --test            Test accuracy of algorithm (default: False)
  -p, --perf            Log performance of the algorithm (default: False)
  -b, --bits            Returns size of hashed message in bytes (default: False)

Currently supported hashes [SHA256, SHA512]
