After you configure the AES 128-bit key through the Edge proxy installer, you can optionally configure an AES 256-bit encryption key to encrypt your data.
Generate Random 256 Bit Aes Key; 256 Bit Aes Key Generator; This might be a noob question, but I couldn't find its answer anywhere online: why does an OpenSSL generated 256-bit AES key have 64 characters? The command I'm using to generate the key is: $ ope.
Supported key lengths and IV lengths 1 You can use only hexadecimal characters, newlines, tabulators and new line characters if you decrypt a string. 2 Input text has an autodetect feature at your disposal. The autodetect detects for you if the content of Input text field is in form of a plain text or a hexadecimal string. You can turn off the feature by clicking on 'OFF'. // A secret key has no structure. It's nothing more than N bytes of data. // It should typically be random data, or bytes that resemble random data such // as the hash of a password. // The number of bytes in the secret key defines the bit-strength of an encryption // algorithm. For example, AES with a 32-byte key is 256-bit AES.
The encryption key is either a plain text file inside the /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, both keys must use the same keystore. If you do not want to configure an AES 256-bit encryption key, click Skip to continue installing the proxy server.
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.
- (Optional) If you want to use AES 256-bit encryption, do the following:
Option Description Java 8 update 141 or earlier Install the Java Cryptography Extension (JCE) and overwrite the policy files in the Java home directory. See Enable AES 256-bit encryption for Java 8 update 141 (8u141) or earlier. Java 8 update 151 or later Edit the java.security policy file to allow the use of unlimited strength keys. See Enable AES 256-bit encryption for Java 8 update 151 (8u151) or later. - To use AES 256-bit encryption, you must also configure the AES 256-bit default encryption key on the instance by navigating to the instance and defining 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.
- After the key is configured on the instance, return to the installer and click Next.
Information!
AES encryption decryption online tool which performs encryption or decryption of an input data based on the given modes (ECB, CBC, CFB or OFB) and key bit sizes (128, 192 or 256 bits) using AES algorithm.
The encryption/decryption with a cipher key of 128, 192, or 256 bits is denoted as AES-128, AES-192, AES-256 respectively.

What is AES Encryption?
The Advanced Encryption Standard (AES) is a block cipher that encrypts a 128-bit block (plaintext) to a 128-bit block (ciphertext), or decrypts a 128-bit block (ciphertext) to a 128-bit block (plaintext).
What is AES encryption/decryption flow?
AES encryption/decryption flows consists a back-to-back sequence of AES transformations, operating on a 128-bit State (data) and a round key. The flows depend on the cipher key length, where total transformation steps for encryption/decryption as follows -
- AES-128 : 40 steps
- AES-192 : 48 steps
- AES-256 : 56 steps
Refer following encryption pseudo code -
Note - Encryption Key Generator 128 Bit
- It is assumed that the 10, 12, or 14 round keys are already derived (expanded) from the 'cipher key' and stored in
round_key_encrypt[]
round_key_encrypt[0]
stores the first 128 bits of the 'cipher key', which is used for the first XOR operation (aka round 0).
Similarly for decryption - follow 'Inverse Cipher', where steps reversed along with invert operations e.g.
invSubButes(tmp), invShiftRows(tmp), invMixColumns(tmp)
