EVM support (v2) in latest version of the kernel adds the file system UUID to
the HMAC calculation. It is controlled by the CONFIG_EVM_HMAC_VERSION and
version 2 is enabled by default. To include the UUID to the signature calculation,
it is necessary to provide '--uuid' or '-u' parameter to the 'sign' command.
UUID can be provided on command line in form of '-uUUID' or '--uuid=UUID'.
version 2 is enabled by default. In this version default UUID is included by
default. Custom value can be supplied via '--uuid=UUID' or '-uUUID' parameter
to the 'sign' command. To use old format HMAC format use '-' as a parameter.
Latest kernel got IMA/EVM support for using X509 certificates and asymmetric key
support for verifying digital signatures. This version uses x509 format by default.
