Hash Generator Tool

Multi-purpose hash tool: MD5, SHA-1, SHA-256, SHA-512, BLAKE2b, Base64 encode/decode, UUID generation, HMAC signing. Pure Python standard library, no API key required.

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	Text to hash/encode
--algo	Algorithm: md5, sha1, sha256, sha512, blake2 (default: sha256)
--encode64	Base64 encode
--decode	Base64 decode
--uuid	Generate UUID
--hmac KEY	HMAC signing with key
--upper	Output uppercase
--count N	Number of UUIDs to generate

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
