Des 16 Key Generator Using Hex
What's new
Version 1.5 now includes a 10 hex key analyzer (10hex.html) than can perform in-depth statistical analysis of known valids, faster piping speed and more keyspace reducing rules.
What is it?
This is a small program written in C++ that will output all possible combinations of 10 hex digits while skipping over certain combinations it believes to be invalid.
Only combinations which meet these criteria will be printed:
• must contain 6-9 unique characters (can be expanded to 5-9 with the -5minuniques option)
• must contain 4-8 numbers
• must contain 2-6 letters
• no 3 consecutive chars are sequential or reverse sequential (<10% occurrence rate)
• no 3 consecutive chars are identical (<3% occurrence rate)
• each character cannot appear more than 3 times (<5% occurrence rate)
• the total difference between all chars cannot be less than 19 or greater than 79
Character 2 Traits
• c2 is not equal to c1 (eliminates 68,719,476,736 combinations) (<1% occurrence rate)
• c2 is not -15 to c1 (eliminates 4,294,967,296 combinations)
• c2 is not -14 to c1 (eliminates 8,589,934,592 combinations)
Character 3 Traits
• c2 and c3 and c10 are not identical
• c3 is not -15 to c2 (eliminates 4,294,967,296 combinations)

• c3 is not +13 to c1 (eliminates 12,884,901,888 combinations)
Then select the bit key length to calculate and press the corresponding button in either full or base; the ASCII or HEX key generated can then be copied to your clipboard manually by a cut-and-paste operation or by clicking on the appropriate Copy To Clipboard button to the right of the Calculated Key field. The standard comprises three block ciphers, AES-128, AES-192, and AES-256, adopted from a larger collection originally published as Rijndael. Each AES cipher has a 128-bit block size, with key sizes of 128, 192, and 256 bits, respectively. The Advanced Encryption Standard (AES), also known by its original name Rijndael is a specification for the encryption of electronic data. It describes a symmetric-key algorithm using the same key for both encrypting and decrypting. Text to base64 Base64 to hex Binary to base64 Variant Beaufort cipher. AES encryption and decryption online tool for free.It is an aes calculator that performs aes encryption and decryption of image, text and.txt file in ECB and CBC mode with 128, 192,256 bit. The output can be base64 or Hex encoded. Blowfish uses a variable key length between 8 and 448 bits long. It is at the choice of the two parties exchanging data to agree what length they use. Most other block cipher encryption methods have a fixed length key. For example, DES has a 64-bit key (but only uses 56 of them) and Triple DES has a 192-bit key (but only uses 168 of them).

Without keyspace reducing rules there are 1,099,511,627,776 (16^10) combinations in the keyspace (~13,194 GB in wordlist form).
Applying these rules brings it down to 564,561,702,612 combinations or 51.3% of the original keyspace (~6,775 GB in wordlist form).
Using the -risky parameter will bring it down even further to 367,647,332,933 or 33.4% of the keyspace (~4,412 GB in wordlist form) but with a slightly decreased chance of success.
If -no01 is used..
-without any rules there would be 289,254,654,976 (14^10) combinations (~3,471.06 GB)
-using the default rules reduces it to 183,780,015,460 combinations (or 63.5% of the keyspace) (~2,205.36 GB)
-using the -risky parameter reduces it to 134,081,483,174 combinations (or 46.3% of the keyspace) (~1,608.98 GB)

The Data Encryption Standard (DES) is a symmetric-key block cipher published by the National Institute of Standards and Technology (NIST).
DES is an implementation of a Feistel Cipher. It uses 16 round Feistel structure. The block size is 64-bit. Though, key length is 64-bit, DES has an effective key length of 56 bits, since 8 of the 64 bits of the key are not used by the encryption algorithm (function as check bits only). General Structure of DES is depicted in the following illustration −
Since DES is based on the Feistel Cipher, all that is required to specify DES is −
- Round function
- Key schedule
- Any additional processing − Initial and final permutation
Initial and Final Permutation
The initial and final permutations are straight Permutation boxes (P-boxes) that are inverses of each other. They have no cryptography significance in DES. The initial and final permutations are shown as follows −
Round Function
The heart of this cipher is the DES function, f. The DES function applies a 48-bit key to the rightmost 32 bits to produce a 32-bit output.
Expansion Permutation Box − Since right input is 32-bit and round key is a 48-bit, we first need to expand right input to 48 bits. Permutation logic is graphically depicted in the following illustration −
The graphically depicted permutation logic is generally described as table in DES specification illustrated as shown −
XOR (Whitener). − After the expansion permutation, DES does XOR operation on the expanded right section and the round key. The round key is used only in this operation.
Substitution Boxes. − The S-boxes carry out the real mixing (confusion). DES uses 8 S-boxes, each with a 6-bit input and a 4-bit output. Refer the following illustration −
The S-box rule is illustrated below −
There are a total of eight S-box tables. The output of all eight s-boxes is then combined in to 32 bit section.
Straight Permutation − The 32 bit output of S-boxes is then subjected to the straight permutation with rule shown in the following illustration:
Key Generation
The round-key generator creates sixteen 48-bit keys out of a 56-bit cipher key. The process of key generation is depicted in the following illustration −
The logic for Parity drop, shifting, and Compression P-box is given in the DES description.

Avalanche effect − A small change in plaintext results in the very great change in the ciphertext.
Completeness − Each bit of ciphertext depends on many bits of plaintext.
During the last few years, cryptanalysis have found some weaknesses in DES when key selected are weak keys. These keys shall be avoided.
