Sujet: [pcre-dev] Query: Regarding normal patterns to PCRE
Dear sir,

I am Sajan.S, Researcher from Amrita Univeristy India. I am working on custom alert correlation engine for networks. I am using snort rules; specifically content part.

I would like to know:

1. Is there a library available to convery snort payloads parts (contents) to pcre?
2. If no library is available; How to use pcre engine to generate a new one from normal string patterns.

for eg:

Need to collapse /cabababc/ down to /c(?:ab){3}c/.

so my input is: /cabababc/

output is : /c(?:ab){3}c/

Looking forward to hear from you!

Thanks & Regards,
Sajan.S
