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
