Fields

filter: Vec<u8>

/Filter — usually “Standard”

v: i64

/V — algorithm version (0, 1, 2, 3, 4, 5)

length: i64

/Length — key length in bits (default 40)

r: i64

/R — revision of the Standard handler (2, 3, 4, 5, 6)

o: Vec<u8>

/O — owner password hash (32 or 48 bytes)

u: Vec<u8>

/U — user password hash (32 or 48 bytes)

p: i32

/P — permission flags (signed 32-bit)

encrypt_metadata: bool

/EncryptMetadata — default true

oe: Option<Vec<u8>>

/OE — owner encryption key (R=5/6, 32 bytes)

ue: Option<Vec<u8>>

/UE — user encryption key (R=5/6, 32 bytes)

perms: Option<Vec<u8>>

/Perms — permissions validation (R=6, 16 bytes)

cf: Option<CryptFilterMap>

/CF — crypt filter map

stm_f: Option<Vec<u8>>

/StmF — default stream crypt filter name

str_f: Option<Vec<u8>>

/StrF — default string crypt filter name
