Module cssm 

CSSM structures that appear inside keychain blobs, as types.

These are the fixed-layout C structs from Apple’s CDSA headers (CSSM_KEYHEADER, CSSM_GUID, CSSM_DATE) and KeyBlob::WrappedFields from ssblob.h. They are modelled field by field rather than carried as opaque bytes, so a key blob written here can be compared with one macOS wrote field by field, and so the values this code chooses are visible in the source instead of hidden in a hex literal.

Modules

algorithm

The CSSM_ALGORITHMS values this code needs to name.

encrypt_mode

CSSM_ENCRYPT_MODE values used here.

key_attr

CSSM_KEYATTR_FLAGS bits.

key_format

CSSM_KEYBLOB_FORMAT values used here.

key_usage

CSSM_KEYUSE bits.

Structs

CssmDate

CSSM_DATE: eight ASCII digits, YYYYMMDD, or all zeroes for “unset”.

Guid

CSSM_GUID. Stored big-endian in a keychain, unlike the host-order form the CSSM API uses in memory.

KeyHeader

CSSM_KEYHEADER, the 76-byte header of every stored key.

WrappedKeyFields

KeyBlob::WrappedFields: how the key that follows was wrapped.

Enums

KeyBlobType

CSSM_KEYBLOB_TYPE.

KeyClass

CSSM_KEYCLASS.
