The attribute set of the symmetric key that protects one item.

Every field here holds the value macOS writes for an item key. Two are worth pointing out because they look wrong:

• key_class is 17, the symmetric-key relation id, not a CSSM_KEYCLASS constant.
• print_name is the 20-byte ssgp label rather than a readable name.

Fields

key_class: u32

print_name: Vec<u8>

alias: Vec<u8>

permanent: bool

private: bool

modifiable: bool

label: [u8; 20]

The label shared with the item’s ssgp payload; how the two are linked.

application_tag: Vec<u8>

key_creator: Vec<u8>

The CSP that created the key, as a braced GUID string with a terminator.

key_type: u32

CSSM_ALGID_3DES_3KEY_EDE.

key_size_in_bits: u32

effective_key_size: u32

start_date: Vec<u8>

Eight zero bytes for “unset”, stored as a blob rather than a date.

end_date: Vec<u8>

sensitive: bool

always_sensitive: bool

extractable: bool

never_extractable: bool

encrypt: bool

decrypt: bool

derive: bool

sign: bool

verify: bool

sign_recover: bool

verify_recover: bool

wrap: bool

unwrap: bool
