Scallion: a GPU-based Onion hash generator


Scallion can help us use OpenCL to create GPG keys and .onion addresses for Tor hidden services. Scallion is developed and run on the Mono software platform, and has been successfully tested on the Arch Linux platform. The tool runs on .NET 3.5+ (tested on Windows 7 and Windows Server 2008 platforms).

Scallion is still in the testing stage and is under active development, but it can be used normally now. Our development is currently focused on improvements in performance, user interface, and installation difficulty, rather than in key generation and related algorithms.

Tool dependency

1. Install and configure OpenCL and related drivers.

2. OpenSSL, under the Windows environment, already contains pre-built x64 DLL.

3. Under the Windows platform, V C ++ Redistributable 2008 is required .

Multi-mode hash

Scallion supports searching for single or multi-mode hashes through primitive regular expression statements, and currently only supports character types (such as [absd]). The “.” Character represents any character, the Onion address length is fixed at 16 characters, and the GPG fingerprint is 40 characters. You can use “$” to find a prefix or suffix match, such as DEAD $. In addition, you can also use pipe statements (such as pattern1 | pattern2) to find multi-mode hashes. Of course, the speed of this search mode is definitely not optimistic.

Sample query

mono scallion.exe prefix[234567] mono scallion.exe -c prefix scallion hashes mono scallion.exe -c "prefix|scallion|hashes" mono scallion.exe .........badbeef mono scallion.exe --gpg badbeef$ # 生成GPG密钥 mono scallion.exe "suffixa$|suffixb$|prefixa|prefixb|a.suffix$|a.test.$"

Scallion working mechanism

1. Use OpenSSL and CPU to generate RSA key

2. Send the key to the GPU

3. Increase the public index of the key

4. Hash the key

5. If the generated hash does not partially conflict, return to the third step

6. If the generated key fails the PKCS # 1 v2.1 and sanity check, return to the third step

7. Generate a brand new key

Speed ​​/ Performance

The initial RSA key generation is done on the CPU, and the SHA1 hash calculation is done on the GPU. Given below is a calculation speed table for common GPUs:
