It uses a hard-coded 32-bit XOR key, 0xDEADBEEF, combined with a
bitwise NOT operation over 4-byte chunks. This makes decryption trivial
for any analyst, incident responder, or defender with access to an
encrypted .lckd file. The scheme provides no meaningful confidentiality, no integrity
protection, no authentication, no per-file randomness, and no key
derivation.
