AES Encryption Tool

Encrypts sensitive textual data and digital files using industry-standard Advanced Encryption Standard algorithms. The utility supports multiple modes of operation, including AES-256-GCM, AES-CBC, and AES-CTR, allowing users to select the appropriate cryptographic method for their needs. All encryption and decryption processes execute entirely within the browser environment, meaning sensitive data does not need to be uploaded or processed on a remote server. This client-side operation maintains user privacy while securing information through robust mathematical transformations based on a provided key. Security professionals, developers building secure applications, and individuals handling confidential communications utilize this tool to protect data integrity. It provides a reliable way to test encryption protocols or securely prepare files for transmission across untrusted networks.
