Can i check from kernel driver whether file signed with real certificate(like VeriSign or GlobalSign)? Do anybody have code which can do this? Thanks!

  • If you intend to go down this route, note that the OpenSSL license and the GPL license are probably incompatible enough that you should _not_ move OpenSSL into the kernel, except as a toy for yourself. If you intend on distributing the results to others, you should pick a GPL-licensed cryptography toolkit. – sarnold May 02 '12 at 00:04

No. While the kernel has some support for certain cryptographic operations, it does not have a full SSL implementation (which would be necessary to verify certificate chains), nor does it have an embedded list of trusted CAs.
