mkfs.ubifs: Add authentication support
This adds support for authenticated UBIFS images. In authenticated images all UBIFS nodes are hashed as described in the UBIFS authentication whitepaper. Additionally the superblock node contains a hash of the master node and itself is cryptographically signed in a node following the superblock node. The signature is in PKCS #7 CMS format. To generate an authenticated image these options are necessary: --hash-algo=NAME hash algorithm to use for signed images (Valid options include sha1, sha256, sha512) --auth-key=FILE filename or PKCS #11 uri containing the authentication key for signing --auth-cert=FILE Authentication certificate filename for signing. Unused when certificate is provided via PKCS #11 Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
