|
|
Hyperscan is a high-performance multiple regex matching library.
|
|
It follows the regular expression syntax of the commonly-used
|
|
libpcre library, but is a standalone library with its own C API.
|
|
|
|
Hyperscan uses hybrid automata techniques to allow simultaneous
|
|
matching of large numbers (up to tens of thousands) of regular
|
|
expressions and for the matching of regular expressions across
|
|
streams of data.
|
|
|
|
Hyperscan is typically used in a DPI library stack.
