This AES Encrypt and Decrypt tool is built for developers, students, educators, and security professionals who need a reliable environment to explore and test AES-based encryption. The interface allows you to configure core encryption parameters such as cipher mode, padding mode, key size, salt size, and passphrase. Once these are defined, you can provide a message to be encrypted or decrypted with a single click. This tool is ideal for understanding how different settings affect AES behavior, validating cryptographic implementations, or preparing mock data for testing purposes.
While all processing is done securely on the server side and we do not log or store any user inputs, we strongly discourage using this tool for production data or any real-world secrets. This site is designed for learning, experimentation, and prototyping—not for handling sensitive, live information. For production use, always work within secure, audited systems and libraries that meet your organization’s compliance standards. Use this tool as a sandbox to deepen your understanding of encryption without putting real data at risk.
