An encryption algorithm is a mathematical function that transforms plaintext into had advanced to the point that it was possible to 'crack' a DES key in less than 24 Encrypting the same data with a different key will produ
function keyFromPassword(password){ // We need 24 bytes for the key, and another 48 bytes for the salt const keyPlusHashingSalt = stretchString(password, 'salt', 24 + 48); return { cipherKey: keyPlusHashingSalt.slice(0,24), hashingSalt: keyPlusHashingSalt.slice(24) }; } Now we can use the generated key to encrypt any data: function encrypt(key, sourceData){ const iv = Buffer.alloc(16, 0); // Initialization vector const cipher = crypto.createCipheriv('aes-192-cbc', key.cipherKey, iv); let
The problem I am having is to get the encryption that is only 24 bytes max where I get 48 each time. AES encryption uses a single key as a part of the encryption process. The key can be 128 bits (16 bytes), 192 bits (24 bytes), or 256 bits (32 bytes) in length. Given that the fastest computer would take billions of years to run through every permutation of a 256-bit key, AES is considered an extremely secure encryption standard.

This may not result in the output of the Feistel network preserving the format of the input, but it is possible to iterate the Feistel network in the same way that the cycle-walking technique does to ensure that format can be preserved.

AES supports 128, 192, and 256-bit encryption, which can be determined by the key size, 128-bit encryption key size is 16 bytes, the 192-bit encryption key is 24 bytes and 256-bit encryption key size is 32 bytes. So sometimes the (triple) DES key lengths are referred to as 56 bit, 112 bit or 168 bits instead of 64, 128 or 192 bits respectively. Usually cryptographic API's still require you to enter 8, 16 or 24 bytes despite of this. AES fortunately does away with all this.

Custom Encryption Key One other way to address the multiple server and different user issue is to use a specific encryption key. ConvertTo-SecureString cmdlet allows a key to be provided for the encryption. The valid encryption key lengths are 16, 24, and 32 bytes.

For example, output from a typical block cipher would turn credit card number into a hexadecimal (e.g.0x96a45cbcf9c2a9425cde9e274948cb67, 34 bytes, hexadecimal digits) or Base64 value (e.g. lqRcvPnCqUJc3p4nSUjLZw==, 24 bytes, alphanumeric and special characters), which will break any existing applications expecting the credit card number to be a 16-digit number.
lqRcvPnCqUJc3p4nSUjLZw==, 24 bytes, alphanumeric and special characters), which will break any existing applications expecting the credit card number to be a 16-digit number. AES encryption only supports 128-bit (16 bytes), 192-bit (24 bytes) or 256-bit key (32 bytes) lengths, so we'll need to create or generate an appropriate key. For simplicity, let's create a simple byte array of ascending numbers. We'll use a 128-bit key, so we'll need a 16-byte array. Long way: [Byte[]] $key = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16) It will require 24 characters in base64. An AES 256-bit key can be expressed as a hexadecimal string with 64 characters.
