shader1

Generate SHA-1.

Based on https://github.com/cuihaoleo/gpg-fingerprint-filter-gpu

How to use:

1. Get CUDA and Python installed
2. use make or build.sh (for non-root env) to build shader1
3. python3 [extract.py](extract.py) your_pfx.pfx password114514 to extract the DER file
4. run ./shader1 [pattern] [start_at] [stop_when]
5. python3 [assemble.py](assemble.py) your_pfx.pfx password114514 output.pfx [64-bit-hash] [key name]

Optional:

Modify found.py to trigger something when a match is found.

Pattern

• Only matches beginning part of a string.
• A hex digit means itself.
• Other Latin alphabets (g to z) are to match any hex digit.
• {N} to repeat previous digit or group for N times.
• (PATTERN) a group pattern.
• Use | to split multiple patterns.

Examples:

• deadbeef equals to regex ^deadbeef
• x{8} equals to regex ^([0-9a-f])\1{7}$
• (xy){4} equals to regex ^([0-9a-f][0-9a-f])\1{3}
• xxxxa{4} equals to regex ^([0-9a-f])\1{3}aaaa

Start at and Stop when

start_at: a 32-bit number, 0-4294967295 to specify the starting lower-32bit stop_when: stop when finding N matches, defaults to 1.
