The following illustration shows how symmetric key encryption works: Figure 1. Symmetric key encryption. AES-256, which has a key length of 256 bits, supports the largest bit size and is practically unbreakable by brute force based on current computing power.
The all-in-one ultimate online toolbox that generates all kind of keys! Every coder needs All Keys Generator in its favorites! It is provided for free and only supported by ads and donations. AES is a strong algorithm to encrypt or decrypt the data. Java,.NET and C provide different implementation to achieve this kind of encryption. Java has provided certain API's by which data can be encrypted using AES algorithm. Steps to encrypt the data using AES algorithm. Feb 20, 2014 Hi, geezer how come when I change the aes.KeySize to 256 (and the AesKey to 32 character length) the returned encrypted string is exactly the same as it is for 128 bit? It doesnt look like the aes.KeySize code is doing anything at all. For this situation, AesCryptoServiceProvider. KeySize Property Gets or sets the size, in bits, of the secret key. 256-bit encryption is a data/file encryption technique that uses a 256-bit key to encrypt and decrypt data or files. It is one of the most secure encryption methods after 128- and 192-bit encryption, and is used in most modern encryption algorithms, protocols and technologies including AES and SSL.
Advanced Encryption Standard(AES) is a symmetric encryption algorithm. AES is the industry standard as of now as it allows 128 bit, 192 bit and 256 bit encryption.Symmetric encryption is very fast as compared to asymmetric encryption and are used in systems such as database system. Following is an online tool to generate AES encrypted password and decrypt AES encrypted password. It provides two mode of encryption and decryption ECB and CBC mode.

Usage Guide
Any plain-text input or output that you enter or we generate is not stored on this site, this tool is provided via an HTTPS URL to ensure that text cannot be stolen.
For encryption, you can either enter the plain text, password, an image file or a .txt file that you want to encrypt. Now choose the block cipher mode of encryption. ECB(Electronic Code Book) is the simplest encryption mode and does not require IV for encryption. The input plain text will be divided into blocks and each block will be encrypted with the key provided and hence identical plain text blocks are encrypted into identical cipher text blocks. CBC mode is highly recommended and it requires IV to make each message unique. If no IV is entered then default will be used here for CBC mode and that defaults to a zero based byte[16].
The AES algorithm has a 128-bit block size, regardless of whether you key length is 256, 192 or 128 bits. When a symmetric cipher mode requires an IV, the length of the IV must be equal to the block size of the cipher. Hence, you must always use an IV of 128 bits (16 bytes) with AES.
AES provides 128 bit, 192 bit and 256 bit of secret key size for encryption. Things to remember here is if you are selecting 128 bits for encryption, then the secret key must be of 16 bits long and 24 and 32 bits for 192 and 256 bits of key size. Now you can enter the secret key accordingly. By default, the encrypted text will be base64 encoded but you have options to select the output format as HEX too.
Similarly, for image and .txt file the encrypted form will be Base64 encoded.
Below is a screenshot that shows a sample usage of this online AES encryption tool.
AES decryption has also the same process. By default it assumes the entered text be in Base64. The input can be Base64 encoded or Hex encoded image and .txt file too. And the final decrypted output will be Base64 string. If the intended output is a plain-text then, it can be decoded to plain-text in-place.

But if the intended output is an image or .txt file then you can use this tool to convert the base64 encoded output to an image.
