GoCrypt Basic: Quick Start Guide for Beginners—
Introduction
GoCrypt Basic is an entry-level encryption tool designed for individuals and small teams who need reliable, easy-to-use file and message encryption without a steep learning curve. This guide walks you through what GoCrypt Basic offers, why you might choose it, and how to get started securing your data quickly.
What is GoCrypt Basic?
GoCrypt Basic is a lightweight cryptography application focused on simplicity and essential features. It provides:
- File encryption and decryption for local storage
- End-to-end encrypted messaging between users (where supported)
- Password-based key derivation and secure passphrase storage
- Cross-platform support (Windows, macOS, Linux)
Its goal is to make strong cryptography accessible to non-experts by offering sensible defaults and a minimal interface.
Why Choose GoCrypt Basic?
Choose GoCrypt Basic if you want:
- Easy setup with minimal configuration
- Strong default security without needing to understand complex cryptography
- A tool for everyday use: encrypting files before cloud upload, sending protected messages, or sharing sensitive documents with colleagues
Core Concepts (Plain Language)
- Encryption converts readable data into ciphertext using a key so only authorized parties can read it.
- Decryption converts ciphertext back to readable data using the correct key.
- A passphrase is a human-memorable secret that often protects cryptographic keys.
- Key derivation functions (KDFs) turn passphrases into strong keys suitable for encryption. GoCrypt Basic uses a secure KDF by default.
System Requirements
- Windows 10 or later, macOS 10.14 or later, or a modern Linux distribution
- 200 MB free disk space
- Internet connection for initial setup and updates (not required for offline encryption/decryption)
Installing GoCrypt Basic
- Download the installer for your platform from the official GoCrypt website.
- Run the installer and follow the on-screen prompts. On Linux, extract the tarball and run the included install script or use the provided AppImage.
- Launch GoCrypt Basic after installation. The first run will prompt you to create a master passphrase.
Creating Your Master Passphrase
- Pick a passphrase that is long and unique (a sentence or 3–5 unrelated words).
- Avoid reusing passwords from other accounts.
- Write it down and store it in a secure location (or use a password manager).
GoCrypt Basic uses this passphrase to derive your encryption keys via a strong KDF.
First-Time Setup Walkthrough
- Open GoCrypt Basic.
- Create and confirm your master passphrase.
- Optionally enable a local recovery key (recommended for teams) and store it securely.
- Choose default file locations for encrypted files and application configuration.
- Optionally enable automatic updates.
Encrypting Files (Step-by-Step)
- Click “Encrypt File.”
- Select the file(s) or folder you want to encrypt.
- Choose a recipient (for shared encrypted files) or select “Private” for local-only encryption.
- Confirm or enter an additional passphrase if you want a file-specific password.
- Click “Encrypt.” GoCrypt Basic will create an encrypted file with a .gcb extension.
Example use cases:
- Encrypt a tax spreadsheet before uploading to cloud storage.
- Protect a one-off PDF before emailing.
Decrypting Files
- Click “Decrypt File.”
- Select the .gcb file.
- Enter your master passphrase or the file-specific passphrase.
- Choose an output location and click “Decrypt.”
Secure Messaging (If Applicable)
- To message securely, add contacts by sharing public keys or invite links.
- Compose a message, select the contact, and send—GoCrypt Basic will encrypt end-to-end.
- Messages are stored encrypted on your device and decrypted only with your passphrase.
Sharing Encrypted Files with Others
- Export a public key or generate a recipient link.
- Recipients import your public key into their GoCrypt app.
- Encrypt files selecting that recipient so only they can decrypt them.
Backup and Recovery
- Regularly back up your encrypted files and the application configuration.
- Store your master passphrase and any recovery keys in at least two secure locations (e.g., password manager + offline paper copy).
- If you lose your passphrase and recovery key, encrypted data cannot be recovered.
Tips for Safe Use
- Keep software updated.
- Use a strong, unique master passphrase.
- Prefer key-based sharing over passphrase-only when possible.
- Limit sharing of encrypted files to trusted recipients.
- Verify public keys out-of-band for high-security sharing (e.g., in person or via a trusted channel).
Troubleshooting Common Issues
- “Incorrect passphrase”: check for typos, Caps Lock, and confirm you’re using the master or file-specific passphrase.
- “Cannot open file”: ensure you’re selecting the .gcb file and it isn’t corrupted.
- Sync issues: check internet connection and update settings if using cloud sync.
When to Upgrade to GoCrypt Pro
Consider upgrading if you need:
- Enterprise-grade user management and auditing
- Hardware-backed key storage (YubiKey, Secure Enclave)
- Larger file-size support and faster performance
- Advanced sharing controls and team policies
Summary
GoCrypt Basic makes everyday encryption straightforward: install, create a strong master passphrase, encrypt files or messages, and securely share keys with trusted contacts. It’s tailored for users who need strong defaults and minimal configuration.
