This is the first time I've written a class in Java to do encryption using AES. Since security is involved I would love it if someone could take a look at it and let me know if anything is wrong wi.
The Java KeyGenerator class (
javax.crypto.KeyGenerator
) is used to generate symmetric encryption keys. A symmetric encryption key is a key that is used for both encryption and decryption of data, by a symmetric encryption algorithm. In this Java KeyGenerator tutorial I will show you how to generate symmetric encryption keys. Creating a KeyGenerator Instance
Before you can use the Java
KeyGenerator
class you must create a KeyGenerator
instance. You create a KeyGenerator
instance by calling the static method getInstance()
passing as parameter the name of the encryption algorithm to create a key for. Here is an example of creating a Java KeyGenerator
instance: This example creates a
KeyGenerator
instance which can generate keys for the AES encryption algorithm. Initializing the KeyGenerator
After creating the
KeyGenerator
instance you must initialize it. Initializing a KeyGenerator
instance is done by calling its init()
method. Here is an example of initializing a KeyGenerator
instance: The
KeyGenerator
init()
method takes two parameters: The bit size of the keys to generate, and a SecureRandom
that is used during key generation. Generating a Key
Once the Java
KeyGenerator
instance is initialized you can use it to generate keys. Generating a key is done by calling the KeyGenerator
generateKey()
method. Here is an example of generating a symmetric key: Right 1
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
128 Bit Encryption Key Generator
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.
Aes 128 Bit Encryption Java
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.
Aes 256 Bit Encryption
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.
