Encrypt and decrypt text using the Advanced Encryption Standard (AES) algorithm.
AES (Advanced Encryption Standard) is a symmetric encryption algorithm widely used to secure sensitive data. It was established by the U.S. National Institute of Standards and Technology (NIST) in 2001 and is now used worldwide. AES transforms readable data (plaintext) into an unreadable format (ciphertext) using a secret key. The same key is used for both encryption and decryption. AES processes data in blocks of 128 bits and supports key lengths of 128, 192, or 256 bits, with longer keys providing stronger security.
1) Use strong, complex passwords for encryption. 2) AES-256 (with 256-bit key) is the most secure variant and recommended for sensitive data. 3) Keep your encryption keys secure and never share them openly. 4) CBC and CTR modes are generally more secure than ECB mode, which should be avoided for most applications. 5) This tool is for educational purposes - for highly sensitive information, use dedicated security software. 6) Remember that client-side encryption in a browser has limitations and isn't suitable for high-security applications.
AES is a symmetric block cipher adopted by the U.S. government and widely used worldwide. It processes data in 128-bit blocks with key lengths of 128, 192, or 256 bits.
Security: Very strong - AES-256 is considered secure against quantum computing attacks and is widely trusted for top-secret information.
Use cases: Government and military communications, financial services, VPNs, disk encryption, secure messaging applications, cloud storage protection, and protection of personal data.
