Finding XREFs

Generating code Signatures by data or code xrefs and finding the shortest ones is also supported:

Signature searching

Searching for Signatures works for supported formats:

Just enter any string containing your Signature, it will automatically try to figure out what kind of Signature format is being used:

Currently, all output formats you can generate are supported.

Match(es) of your signature will be printed to console:

Other

This plugin uses qis's AVX2-optimized signature searching library: https://github.com/qis/signature

If the CPU doesn't support AVX2, it will fallback to the slow builtin IDA functions.
