AES Encryption Tool
Encrypt and decrypt text or files with AES-256-GCM, AES-CBC, or AES-CTR. Runs in your browser.
What AES Encryption Tool does
The AES Encryption Tool on Inventive HQ is a client-side utility that lets users encrypt and decrypt text or files using industry-standard AES algorithms. It supports multiple operational modes—including AES-256-GCM, AES-CBC, and AES-CTR—allowing users to select the cryptographic method that best fits their security needs. Because all processing happens within the browser, sensitive data never leaves the user's device, ensuring privacy while providing robust protection through standard mathematical transformations.
How to use the Inventive HQ AES Encryption Tool
- 1
Open the AES Encryption Tool on Inventive HQ
- 2
Choose an encryption mode (AES-256-GCM, AES-CBC, or AES-CTR) and enter or upload your text or file
- 3
Provide a secret key to secure your data
- 4
Initiate encryption; the resulting ciphertext or decrypted output appears instantly in the browser
- 5
Use the same key and mode to decrypt the output and retrieve your original information
Best for
Developers and security-conscious users who need to quickly encrypt or decrypt sensitive text or files locally without uploading data to external servers.
Limitations
- No unit conversion or format transformation features
- Security depends entirely on the secrecy of the user-provided key
- No listed support for file size limits or batch processing
AES Encryption Tool FAQ
- Can I encrypt large files with this tool?
- The tool processes files client-side in the browser; very large files may cause performance issues or timeout depending on the device's capabilities.
- What happens if I lose my encryption key?
- Without the secret key used during encryption, the data cannot be decrypted; the key must be stored securely separately from the ciphertext.
- Is my data sent to Inventive HQ's servers when I use this tool?
- No, all encryption and decryption occur entirely within the user's browser; sensitive information never needs to be uploaded or processed on a remote server.
- Which AES mode provides the best security for general use?
- AES-256-GCM is generally recommended for most use cases as it combines encryption with built-in authentication, offering both confidentiality and integrity protection.
