AES-GCM File Encryption

Security, password & code tools guide

What is AES-GCM File Encryption?

Encrypt or decrypt files with a password using authenticated AES-GCM. AES-GCM File Encryption is designed to generate, inspect, or verify security-related values with configurable inputs. It is useful for quick one-off jobs, office handoffs, development checks, and situations where installing desktop software is inconvenient.

How to use AES-GCM File Encryption

1. Prepare the file, text, or settings you want to work with and keep the original.
2. Add the input in the tool above and adjust the available options for your intended result.
3. Run the tool and review the preview, measurements, or validation details.
4. Download or copy the result, then open it once to confirm the format and content.

Common use cases

• Quickly generate, inspect, sign, hash, and verify security-related data without extra software.
• Prepare content before an upload, email, handoff, or publication.
• Check inputs and outputs visually to catch format mistakes.
• Complete a one-time task from a desktop or mobile browser.

Tips for a better result

Test your settings on a small sample before processing important content. For images, documents, or compressed files, balance output size against readability. For code, data, or security values, double-check character encoding, field names, and the expected format.
