AES Encoder

Advanced Encryption Standard (AES) is a widely used symmetric encryption algorithm. It supports key sizes of 128, 192, and 256 bits, making it versatile for various security needs. Symmetric encryption, such as AES, is preferred for its speed compared to asymmetric encryption and is commonly used in systems like databases.

AES Key Size

AES always uses a 128-bit block size, regardless of the key length. When using a cipher mode that requires an Initialization Vector (IV), the IV must also be 128 bits (16 bytes) in length.

AES Secret Key

For AES encryption, the key length can be 128 bits, 192 bits, or 256 bits. This means that for a 128-bit key, you need a 16-byte (128-bit) secret key; for a 192-bit key, you need a 24-byte (192-bit) secret key; and for a 256-bit key, you need a 32-byte (256-bit) secret key. For instance, a 128-bit key requires a 16-character secret key (since 16 characters * 8 bits/character = 128 bits).

Usage Instructions

You can input the secret key based on the selected key size. By default, the encrypted output will be encoded in Base64, but there is also an option to choose HEX encoding. For images and text files, the encrypted output will be in Base64 format.

The tool provides an easy way to encrypt and decrypt passwords online, ensuring secure handling of sensitive information. Below is an example screenshot demonstrating the use of this AES encryption tool.
