/keys directory or a secret key inside a keystore. If you use a keystore for your AES 128-bit and AES 256-bit encryption keys, they must both use the same keystore.If you are updating an SSL certificate on an Edge proxy server, see Update SSL certificate.
Procedure
- Select the encryption key location.
Option Description File Store Use a file to store a single encryption key. You can use an existing file in the /keys directory, or you can generate a new file. To generate a new file, enter an alias and click Generate. A file containing an encryption key is created. Note: This choice designates both the storage location and the encryption key. If you select File Store, click Next and go to step 5.Create New Java KeyStore Create a keystore to store the encryption key. Java KeyStore File Store the encryption key in an existing Java KeyStore file. - Click Next.
- Select or create the encryption key.
Option Description New Key Create an encryption key and alias. Note: You must use lowercase letters and numbers for the alias name (key name, key alias), per Java KeyStore requirements. To find out more about the keytool utility, see the Java SE Documentation.Use Existing Key Use an existing encryption key in the selected keystore. Import Existing Key Import an encryption key from a different keystore. - Click Next.
- Configure the key on the instance according to the requirements defined in your installer.To configure the key on the instance, navigate to the instance and define a default key. See Configure encryption keys on the instance. Ensure that the key alias, size, and type match the requirements defined in the installer.
- Once the key is configured on the instance, return to the installer and click Next.

Calculation
You can use this plugin to encrypt or decrypt with the Advanced Encryption Standard (AES) one or more complete blocks (so the input message length must be a multiple of 128 bit, aka 32 hex characters, which is 16 bytes). The modes supported are CBC and ECB .
If you are doing production work on systems this old though, you have other security concerns to worry about as well! Encryption methods of keys ssh can generate.
What makes this plugin unique is the possibility to see how the cipher changes the bytes: If you mark a byte somewhere in the process the plugin shows all the bytes it depends on in the previous steps (backwards dependance, what influences what).
The plugin gives you access to the building blocks of AES in detail: You can change the number of rounds, the IV, and even the S-box to see how this effects the result. In addition to entering the data for the message and the key by yourself, there are several 'official' AES test vectors to choose from.
The Advanced Encryption Standard (AES) is a specification for the encryption of electronic data published by the U.S. government as NIST standard in 2001. The standard comprises three block ciphers, AES-128, AES-192, and AES-256, adopted from a larger collection originally published as Rijndael.

Aes Encryption Key Generator
Each AES cipher has a 128-bit block size, with key sizes of 128, 192, and 256 bits, respectively. The AES ciphers have been analyzed extensively and are now used worldwide, as was the case with its predecessor, the Data Encryption Standard (DES). (Source¹ Wikipedia)

The security of the Advanced Encryption Standard (AES) has been analyzed extensively and no 'real' flaw has been found (Source¹ Wikipedia).
This means, that at present, there is no known practical attack on the encryption algorithm itself that would allow someone without knowledge of the key to read data encrypted by AES when correctly implemented. So only side-channel attacks or attacks working with manipulated random-number generators or attacks which grap the key or the plaintext before the encryption was applied may successfully reveal the key or the plaintext.
Some more details didactically prepared about the concepts of security in general and about theoretical attacks against AES can be fould in chapter 1 of the CrypTool Book (Source² CrypTool Book).
