GoXfer is a command-line tool written in Go for securely transferring files using various protocols such as SFTP, with support for parallel transfers, checksum verification, retries, and SSH key authentication.

• Parallel File Transfers: Speed up large transfers with concurrent file transfers.
• Checksum Verification: Ensure file integrity after transfer using SHA256 checksum comparison.
• Retry Mechanism: Automatically retry transfers in case of checksum mismatches.
• Passphrase-Protected SSH Key Support: Authenticate with SSH private keys that are protected by passphrases.
• Customizable Transfer Options: Configure the number of parallel transfers, retries, and more.

git clone https://github.com/JonathanInTheClouds/goxfer.git
cd goxfer

go build -o goxfer cmd/main.go

This will create a binary named goxfer in your project directory.

To transfer files using GoXfer, you can use the following command:

./goxfer --protocol=sftp --host=localhost --port=2222 --username=transferuser --key=/path/to/private_key --srcPath=/path/to/local/files --destDir=/remote/destination/path --parallel=5 --retries=3

./goxfer --protocol=sftp --host=localhost --port=2222 --username=transferuser --key=/home/jonathan/.ssh/id_rsa --srcPath=./file-transfer-container --destDir=/home/transferuser/file-transfer-container --parallel=5 --retries=3

This example transfers the files from the ./file-transfer-container folder to the /home/transferuser/file-transfer-container folder on the remote server using SFTP.

GoXfer automatically verifies file integrity by calculating the SHA256 checksum of both the local and remote files. If the checksums don't match, GoXfer will retry the transfer up to the specified number of retries (default: 3).

You can use a Dockerized SFTP server to test the file transfer functionality. Here’s how to set it up:

In the file-transfer-container folder, run the following commands to build and launch the SFTP server:

docker build -t file-transfer-test .
docker run -p 2222:22 -d file-transfer-test

./goxfer --protocol=sftp --host=localhost --port=2222 --username=transferuser --key=/path/to/private_key --srcPath=/path/to/local/files --destDir=/home/transferuser/file-transfer-container --parallel=5 --retries=3

This will transfer files to the Docker container acting as the SFTP server.
