2012-02-20digsig: changed type of the timestampDmitry Kasatkin1-2/+2
time_t was used in the signature and key packet headers, which is typedef of long and is different on 32 and 64 bit architectures. Signature and key format should be independent of architecture. Similar to GPG, I have changed the type to uint32_t. Signed-off-by: Dmitry Kasatkin <dmitry.kasatkin@intel.com> Signed-off-by: James Morris <jmorris@namei.org>
2012-01-18lib: digital signature config option name changeDmitry Kasatkin1-2/+2
It was reported that DIGSIG is confusing name for digital signature module. It was suggested to rename DIGSIG to SIGNATURE.

2011-11-09crypto: digital signature verification supportDmitry Kasatkin1-0/+64
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. Signed-off-by: Dmitry Kasatkin <dmitry.kasatkin@intel.com> Acked-by: Mimi Zohar <zohar@us.ibm.com>
