| 26 | // acl_codesigning - ACL subject for signature of calling application | |
| 27 | // | |
| 28 | // Note: | |
| 29 | // Once upon a time, a code signature was a single binary blob, a "signature". | |
| 30 | // Then we added an optional second blob, a "comment". The comment was only | |
| 31 | // ancilliary (non-security) data first, but then we added more security data | |
| 32 | // to it later. Now, the security-relevant data is kept in a (signature, comment) | |
| 33 | // pair, all of which is relevant for the security of such subjects. | |
| 34 | // Don't read any particular semantics into this separation. It is historical only | |
| 35 | // (having to do with backward binary compatibility of ACL blobs). | |
