AES [-] - the Advanced Encryption Standard block cipher, available with 128 bit (16 byte), 192 bit (24 byte), and 256 bit (32 byte) keys. 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. 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… 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.

The online tool used expects a 24-byte (48 hex-character) key; thus you should enter E6F1081FEA4C402CC192B65DE367EC3EE6F1081FEA4C402C as the key, duplicating the first 8 bytes; this is the customary way to extend a two-block triple DES key of 16 bytes to a three-block triple DES key of 24 bytes.

In the same manner as the 128-bit input block is arranged in the form of a state array, the algorithm arranges the first 16 bytes of the encryption key in the form of a 4 × 4 matrix of bytes. The following figure shows the four words of the original 128-bit key being expanded into a key schedule consisting of 4 x 11 = 44 words.

Se hela listan på di-mgt.com.au Generally the three keys are generated by taking 24 bytes from a strong random generator and only keying option 1 should be used (option 2 needs only 16 random bytes, but strong random generators are hard to assert and it's considered best practice to use only option 1).
