资 源 简 介
PEFS is a cryptographic stacked file system.
PEFS encrypts files on top of existing file system using per file random tweak value to guarantee different ciphertexts for same files.
Metadata is stored only in encrypted file name, making encrypted backups easy.
PEFS supports arbitrary number of keys per file system, mixing keys in same directory and key chains.
Based on modern cryptographic algorithms: AES and Camellia in XTS mode, PKCS#5v2 and HKDF for key generation.
