About AES Encryption
The Advanced Encryption Standard (AES) is a symmetric encryption algorithm widely used to protect sensitive data. It was established by the U.S. National Institute of Standards and Technology (NIST) in 2001.
Key Features:
- Supports key sizes of 128, 192, and 256 bits
- Block cipher that encrypts data in fixed-size blocks of 128 bits
- Considered highly secure and resistant to various attacks
- Used in numerous security protocols and applications worldwide
Encryption Modes:
- CBC (Cipher Block Chaining): Each block of plaintext is XORed with the previous ciphertext block before being encrypted. Requires an initialization vector (IV).
- ECB (Electronic Codebook): Each block is encrypted independently. Not recommended for most applications as it doesn't hide data patterns well.
- CFB (Cipher Feedback): Converts a block cipher into a stream cipher. Requires an initialization vector (IV).
