ultrabase64 1.0.13

Ultra-fast Base64 encoding/decoding library with SIMD and multithreading support

UltraBase64

Ultra-fast Base64 encoding/decoding library with SIMD and multithreading support, written in Rust for Python.

Features

• Blazing Fast: Utilizes SIMD instructions (AVX2/SSE/NEON) for maximum performance
• Multithreaded: Automatic multithreading for large data sets
• Memory Efficient: Zero-copy operations where possible
• Cross-Platform: Works on Linux, Windows, and macOS
• Easy to Use: Simple Python API

Installation

pip install ultrabase64

Usage

import ultrabase64

# Basic encoding/decoding
data = b"Hello, World!"
encoded = ultrabase64.encode(data)
decoded = ultrabase64.decode(encoded)

print(f"Original: {data}")
print(f"Encoded: {encoded}")
print(f"Decoded: {decoded}")

# Encoding with specific number of threads
large_data = b"x" * 1000000
encoded_threaded = ultrabase64.encode_with_threads(large_data, threads=4)

Performance

UltraBase64 automatically chooses the optimal strategy:

• Small data (< 256KB): Single-threaded with SIMD optimizations
• Large data (>= 256KB): Multi-threaded processing using all available CPU cores
• Custom threading: Use encode_with_threads() for manual control

API Reference

encode(data: bytes) -> str

Encodes bytes to Base64 string with automatic optimization.

decode(data: str) -> bytes

Decodes Base64 string to bytes.

encode_with_threads(data: bytes, threads: int) -> str

Encodes bytes to Base64 string using specified number of threads.
