KeyKiller is a GPU-accelerated version of the KeyKiller project, designed to achieve extreme performance in solving Satoshi Nakamoto's puzzles using modern NVIDIA GPUs. KeyKiller CUDA pushes the limits of cryptographic key search performance by leveraging CUDA, thread-beam parallelism, and batch EC operations. The command-line version is open-source and free to use.
NCrypted - simple file encryption software with GPU support
NCrypted is a simple file encryption software. It is implemented on top of AES 128-bit algorithm.
This software was designed to be as simple as possible, so you won't find any fancy, flashy gui elements or complicated advanced options.
You can also use it directly from command line.
NCrypted can automatically detect and take advantage of your NVidia graphics card to speed up the file processing.
