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
# 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
# Encode
python3 scripts/hash_toolkit.py "Hello World" --encode64
# Decode
python3 scripts/hash_toolkit.py "SGVsbG8gV29ybGQ=" --decode
UUID
# Generate one UUID
python3 scripts/hash_toolkit.py --uuid
# Generate 5 UUIDs
python3 scripts/hash_toolkit.py --uuid --count 5
HMAC
# 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
| Option | Description |
|---|---|
TEXT |

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
