## What it is
A Go CLI tool that splits a file into encrypted fragments using Shamir's Secret Sharing, requiring only a threshold of fragments to reconstruct the original. It eliminates the need to remember a passphrase by distributing the encryption key across the fragments.

## Use cases
- split a sensitive file into encrypted fragments without a password
- reconstruct a file from a threshold of its fragments
- distribute a file across multiple channels to resist interception
- back up a file so no single copy reveals its contents
- encrypt a diary without needing to remember a passcode years later

## When to choose
- you want passphrase-free file encryption via secret sharing
- you need k-of-n threshold reconstruction of a file
- you want a simple cross-platform CLI for fragmenting files

## When to avoid
- you need standard passphrase-based encryption for daily use
- you need to encrypt many files with shared key management
- you need a GUI or enterprise key-management solution
