Usage Instructions

AES AlgorithmAES (Advanced Encryption Standard) is one of the most secure symmetric encryption algorithms

Key SecurityKey length is 32 characters (256 bits), please keep the key secure

Initialization VectorIV increases encryption randomness, use different IV for each encryption

Data SecurityAll encryption/decryption is performed locally, data is not uploaded to servers

📖Tool Introduction
AES Encrypt/Decrypt Tool is a professional data security processing tool based on the Advanced Encryption Standard (AES). AES is a symmetric encryption algorithm standard published by the National Institute of Standards and Technology (NIST), widely used in government, financial, and enterprise critical information systems for data protection. This tool supports AES-256-CBC mode with 256-bit key length, providing industrial-grade data security assurance. All encryption and decryption operations are completed locally in the browser, ensuring data privacy security.
