Hash Toolkit#

All-in-one hash utility supporting multiple algorithms, Base64 encoding/decoding, UUID generation, and HMAC signing. Pure Python standard library, works offline.

Features#

• Hash Algorithms: MD5, SHA-1, SHA-256, SHA-512, BLAKE2b
• Base64: Encode and decode
• UUID: Generate random UUIDs
• HMAC: Sign messages with secret keys
• Pure standard library: Zero dependencies, works offline

Usage#

Hash Generation#

bash

# SHA-256 (default)
python3 scripts/hash_toolkit.py "Hello World"

# MD5
python3 scripts/hash_toolkit.py "Hello World" --algo md5

# SHA-512
python3 scripts/hash_toolkit.py "Hello World" --algo sha512

# BLAKE2b
python3 scripts/hash_toolkit.py "Hello World" --algo blake2

Base64#

bash

# Encode
python3 scripts/hash_toolkit.py "Hello World" --encode64

# Decode
python3 scripts/hash_toolkit.py "SGVsbG8gV29ybGQ=" --decode

UUID#

bash

# Generate one UUID
python3 scripts/hash_toolkit.py --uuid

# Generate 5 UUIDs
python3 scripts/hash_toolkit.py --uuid --count 5

HMAC#

bash

# HMAC-SHA256
python3 scripts/hash_toolkit.py "message" --hmac "secret-key"

# HMAC with different algorithm
python3 scripts/hash_toolkit.py "message" --hmac "secret-key" --algo sha512

Options#

Security Notes#

• MD5 & SHA-1: Not recommended for security purposes (collision vulnerabilities)
• SHA-256/SHA-512/BLAKE2b: Suitable for security applications
• Password storage: Use bcrypt/argon2 instead of simple hashing
• HMAC: Suitable for message authentication
