# Croc Installation Script
|
|
# ==============================================================================
|
|
# Installs croc - Secure, fast file transfer tool
|
|
#
|
|
# Threat Model:
|
|
# - Insecure file transfer methods (email, Dropbox, USB drives)
|
|
# - Cloud storage snooping and data breaches
|
|
# - Man-in-the-middle attacks during file transfer
|
|
# - Metadata exposure in file sharing
|
|
#
|
|
# How Croc Protects:
|
|
# - End-to-end encryption using PAKE (Password Authenticated Key Exchange)
|
|
# - No account or login required
|
|
# - Direct peer-to-peer transfer (optional relay for NAT traversal)
|
|
# - Automatic compression
|
|
# - Resume capability for interrupted transfers
|
