Nextgen-mft: Secure, AI-powered Managed File Transfer (SFTP/HTTPS + Crypto + Anomaly Detection)

Introduction

nextgen-mft is a modular Python library designed for building secure, intelligent, and automated file transfer systems. It enables seamless SFTP, HTTPS, and AI-driven anomaly detection, along with powerful cryptographic utilities like RSA, ECDHE, ChaCha20, and X.509 certificate handling.

Key Features

SFTP & HTTPS Transfers

• Upload/download files securely over SFTP and HTTPS
• SSH key authentication and TLS client cert support

AI-Powered Anomaly Detection

• Detect abnormal transfer behaviors using IsolationForest
• Simple API for training and scoring

Strong Cryptography

• Generate RSA, ECDHE, and DH keys
• AES (CBC) and ChaCha20 encryption support
• Load/save certificates and keys in PEM

Command-Line Interface (CLI)

• Built-in CLI using Typer
• Easily upload files, generate keys, and run anomaly detection

Production-Ready

• Modular architecture
• Ready for pipelines, automation, and cloud workflows

Use Cases

• Enterprise Managed File Transfer (MFT) systems
• Secure partner integrations via HTTPS/SFTP
• Compliance-driven cryptographic workflows
• Real-time anomaly detection in file movements
• CLI-based DevOps automation

Installation

Recommended process:

There are several different ways to install nextgen-mft. However it is recommended to both install and use the package inside python virtual environment.

At the command line using "pip"

$ pip install nextgen-mft

Or, if you have virtualenvwrapper installed.

$ mkvirtualenv nextgen-mft
$ python3 -m pip install nextgen-mft

Installation with Package Manager

Alternatively it is possible to install nextgen-mft using package manager.

Such as yum or dnf

$ yum|dnf install nextgen-mft

Quick CLI Usage

Upload a file via SFTP:

$ python3 -m nextgen_mft.cli.main sftp-upload \
  --host sftp.example.com \
  --username user \
  --key-file ~/.ssh/id_rsa \
  --local-file ./file.txt \
  --remote-path /inbox/file.txt

## **Detect anomalies from file transfer logs**
$ python3 -m nextgen_mft.cli.main detect-anomalies \
  --train-file train_data.json \
  --test-file new_data.json
