Add binary read-only sysfs attributes for the pkey module that can be used to read random protected keys from. Keys are read from these attributes using a cat-like interface. A typical use case for those keys is to encrypt a swap device using the paes cipher. During processing of /etc/crypttab, the random protected key to encrypt the swap device is read from one of the attributes. The following attributes are added: protkey/aes_128 protkey/aes_192 protkey/aes_256 protkey/aes_128_xts protkey/aes_256_xts Each attribute emits a protected key blob for the corresponding key size and cipher mode.
