From 051dbb918c7fb7da8e64a2cd0d804ba73399709f Mon Sep 17 00:00:00 2001 From: Dmitry Kasatkin Date: Fri, 14 Oct 2011 15:25:16 +0300 Subject: crypto: digital signature verification support This patch implements RSA digital signature verification using GnuPG library. The format of the signature and the public key is defined by their respective headers. The signature header contains version information, algorithm, and keyid, which was used to generate the signature. The key header contains version and algorythim type. The payload of the signature and the key are multi-precision integers. The signing and key management utilities evm-utils provide functionality to generate signatures and load keys into the kernel keyring. When the key is added to the kernel keyring, the keyid defines the name of the key.
