key_gc_unused_keys	Garbage collect a list of unreferenced, detached keys
SYSCALL_DEFINE5	Extract the description of a new key from userspace and either add it as a* new key to the specified keyring or update a matching key in that keyring.* If the description is NULL or an empty string, the key type is asked to* generate one from the payload.
keyctl_instantiate_key_common	Instantiate a key with the specified payload and link the key into the* destination keyring if one is given.* The caller must have the appropriate instantiation permit set for this to* work (see keyctl_assume_authority). No other permissions are required.
kdf_ctr	Implementation of the KDF in counter mode according to SP800-108 section 5
datablob_hmac_append
datablob_hmac_verify	verify HMAC before decrypting encrypted key

encrypted_read	rypted_read - format and copy the encrypted data to userspace* The resulting datablob format is:* * On success, return to userspace the encrypted key datablob size.
fscrypt_init_hkdf	Compute HKDF-Extract using the given master key as the input keying material,* and prepare an HMAC transform object keyed by the resulting pseudorandom key.* Afterwards, the keyed HMAC transform object can be used for HKDF-Expand many

move_master_key_secret
fscrypt_ioctl_add_key	Add a master encryption key to the filesystem, causing all files which were* encrypted with it to appear "unlocked" (decrypted) when accessed.* When adding a key for use by v1 encryption policies, this ioctl is
