Cert grabber for DOCSIS modems. Not sure how up to date it is but I know it makes getting certs for modded modems much easier.

This is a variation of FastSnmp, it scans for modems with factory mode enabled and when it finds one it retrieves the serial, the model, the mac, and all the certs it can and saves it to a file.

It retrieves HFC, Downstream and upstream rates, Ethernet and USB macs along with serial and cmFactoryBigRSAPublicKey, cmFactoryBigRSAPrivateKey, cmFactoryCMCertificate, cmFactoryManCertificate, cmFactoryRootCertificate certificates.
This is the compiled for windows version of FastCert, ive included the perl script as well
