Enum FscryptMode 

Source 
pub enum FscryptMode {
    Standard,
    InoLblk64,
    InoLblk32,
}
Expand description

Policy mode derived from fscrypt_policy_v2 flags on FS_IOC_SET_ENCRYPTION_POLICY.

Variants§

§

Standard

Default v2 policy (flags has neither IV_INO_LBLK_64 nor IV_INO_LBLK_32): uses per-file wrapped keys (WrappedKey::Fxfs / FxfsCipher) for files.

§

InoLblk64

FSCRYPT_POLICY_FLAG_IV_INO_LBLK_64: shared hardware keyslot with 64-bit (ino << 32) | lblk_num DUNs and HKDF_CONTEXT_IV_INO_LBLK_64_KEY (4).

§

InoLblk32

FSCRYPT_POLICY_FLAG_IV_INO_LBLK_32: shared hardware keyslot with 32-bit (SipHash(ino) + lblk_num) as u32 DUNs and HKDF_CONTEXT_IV_INO_LBLK_32_KEY (6).
