Quick Start: Encrypting Files with ZXI Encrypter in 5 MinutesZXI Encrypter is a lightweight, user-friendly tool designed to secure files quickly with strong encryption. This guide walks you through a practical five-minute workflow to encrypt files, explains key options, and offers troubleshooting tips so you can confidently protect sensitive data immediately.
What you’ll need (30 seconds)
- A computer running Windows, macOS, or Linux
- ZXI Encrypter installed (download and install from the official site or package manager)
- The file(s) you want to encrypt
- A strong passphrase or a public/private key pair if using asymmetric mode
Note: If you don’t have ZXI installed, installation typically takes under a minute on modern systems. Use the official download to avoid tampered builds.
Step 1 — Choose encryption mode (30 seconds)
ZXI Encrypter commonly offers two modes:
- Symmetric encryption (single passphrase) — faster and ideal for personal use.
- Asymmetric encryption (public/private keys) — better for sharing encrypted files publicly or sending to specific recipients.
Pick symmetric if you’re encrypting files for yourself. Pick asymmetric if you need to grant decryption capability to someone else without sharing your passphrase.
Step 2 — Prepare your passphrase or keys (30 seconds)
For symmetric:
- Use a passphrase at least 12 characters long with a mix of upper/lowercase letters, numbers, and symbols.
For asymmetric:
- Generate a key pair inside ZXI or import an existing key. Keep your private key secure and backed up.
Example strong passphrase: CorrectHorseBatteryStaple!42
Step 3 — Encrypt a file (1–2 minutes)
Using the GUI:
- Open ZXI Encrypter.
- Click “Encrypt” (or “New Encryption”).
- Drag-and-drop your file(s) or click “Add files.”
- Choose encryption mode (symmetric/asymmetric).
- Enter your passphrase or select the recipient’s public key.
- Optionally set output folder and filename pattern.
- Click “Start” or “Encrypt.”
Using the command line (example):
# Symmetric encryption zxi encrypt --input report.pdf --output report.pdf.zxi --passphrase "YourStrongPassphrase" # Asymmetric encryption (recipient public key) zxi encrypt --input report.pdf --output report.pdf.zxi --recipient-key /path/to/recipient_pubkey.pem Progress should complete within seconds to minutes depending on file size.
Step 4 — Verify the encrypted file (30 seconds)
- Confirm the output file (e.g., report.pdf.zxi) exists and is significantly different in size/contents from the original.
- Attempt a decrypt-to-temp with your passphrase or private key to make sure decryption works:
zxi decrypt --input report.pdf.zxi --output /tmp/report.pdf --passphrase "YourStrongPassphrase"If the decrypted file matches the original, encryption succeeded.
Step 5 — Share or store securely (30 seconds)
- For symmetric: share the passphrase via a secure channel (not email), e.g., in-person, encrypted messaging, or a password manager’s secure note.
- For asymmetric: share the .zxi file via email or cloud; do not share your private key.
Store encrypted files in backups or cloud storage—encryption protects them even if storage is breached.
Common options and what they mean (brief)
- Compression: compress before encryption to save space and reduce plaintext footprint.
- Authenticated encryption: ensures integrity (recommended — usually enabled by default).
- Iteration count / KDF: increases passphrase hardness vs brute-force; use default or higher for important files.
- Metadata stripping: removes file names/timestamps from the encrypted package for greater privacy.
Troubleshooting
- “Wrong passphrase” error: check for typos, caps-lock, or using the wrong passphrase vs key.
- Decryption fails with asymmetric mode: ensure you’re using the correct private key and that public key matched at encryption.
- Very slow encryption: large files or very high KDF iterations. Try using default iterations or encrypt large files on a faster machine.
Security tips
- Use a unique passphrase per encrypted project.
- Back up private keys and passphrases to a secure location (hardware token or encrypted password manager).
- Keep ZXI updated to receive crypto and implementation fixes.
- Prefer authenticated encryption and KDF iteration counts appropriate to your threat model.
