  71         to be secure.
  72
  73         Many API functions taking SecStaticCodeRef arguments will also directly
  74         accept a SecCodeRef and apply this translation implicitly, operating on
  75         its result or returning its error code if any. Each of these functions

 134         @function SecCodeCopyGuestWithAttributes
 135         This is the omnibus API function for obtaining dynamic code references.
 136         In general, it asks a particular code acting as a code host to locate
 137         and return a guest with given attributes. Different hosts support
 138         different combinations of attributes and values for guest selection.
 139
 140         Asking the NULL host invokes system default     procedures for obtaining
 141         any running code in the system with the attributes given. The returned
 142         code may be anywhere in the system.
 143
 144         The methods a host uses to identify, separate, and control its guests
 145         are specific to each type of host. This call provides a generic abstraction layer
 146         that allows uniform interrogation of all hosts. A SecCode that does not
 147         act as a host will always return errSecCSNoSuchCode. A SecCode that does
 148         support hosting may return itself to signify that the attribute refers to
 149         itself rather than one of its hosts.
 150
 151         @param host A valid SecCode object reference representing code running
 152         on the system that acts as a Code Signing host. As a special case, passing
 153         NULL indicates that the Code Signing root of trust should be used as a starting
 154         point. Currently, that is the system kernel.
 155         @param attributes A CFDictionary containing zero or more attribute selector
 156         values. Each selector has a CFString key and associated CFTypeRef value.
 157         The key name identifies the attribute being specified; the associated value,
 158         whose type depends on the the key name, selects a particular value or other
 159         constraint on that attribute. Each host only supports particular combinations
 160         of keys and values,     and errors will be returned if any unsupported set is requested.
 161         As a special case, NULL is taken to mean an empty attribute set.
 162         Note that some hosts that support hosting chains (guests being hosts)
 163         may return sub-guests in this call. In other words, do not assume that
 164         a SecCodeRef returned by this call is a direct guest of the queried host
 165         (though it will be a proximate guest, i.e. a guest's guest some way down).
 166         Asking the NULL host for NULL attributes returns a code reference for the system root
 167         of trust (at present, the running Darwin kernel).
 168         @param flags Optional flags. Pass kSecCSDefaultFlags for standard behavior.
 169         @param guest On successful return, a SecCode object reference identifying
 170         the particular guest of the host that owns the attribute value(s) specified.
 171         This argument will not be changed if the call fails (does not return errSecSuccess).
 172         @result Upon success, errSecSuccess. Upon error, an OSStatus value documented in
 173         CSCommon.h or certain other Security framework headers. In particular:
 174         @error errSecCSUnsupportedGuestAttributes The host does not support the attribute
 175         type given by attributeType.
 176         @error errSecCSInvalidAttributeValues The type of value given for a guest
 177         attribute is not supported by the host.
 178         @error errSecCSNoSuchCode The host has no guest with the attribute value given
 179         by attributeValue, even though the value is of a supported type. This may also
 180         be returned if the host code does not currently act as a Code Signing host.
 181         @error errSecCSNotAHost The specified host cannot, in fact, act as a code
 182         host. (It is missing the kSecCodeSignatureHost option flag in its code
 183         signature.)
 184         @error errSecCSMultipleGuests The attributes specified do not uniquely identify
 185         a guest (the specification is ambiguous).

 361                 the code. Suitable for display to a (knowledeable) user.
 362         @constant kSecCodeInfoDigestAlgorithm A CFNumber indicating the kind of cryptographic
 363                 hash function chosen to establish integrity of the signature on this system, which
 364         is the best supported algorithm from kSecCodeInfoDigestAlgorithms.
 365         @constant kSecCodeInfoDigestAlgorithms A CFArray of CFNumbers indicating the kinds of
 366                 cryptographic hash functions available within the signature. The ordering of those items
 367                 has no significance in terms of priority, but determines the order in which
 368         the hashes appear in kSecCodeInfoCdHashes.
 369         @constant kSecCodeInfoPlatformIdentifier If this code was signed as part of an operating
 370                 system release, this value identifies that release.
 371         @constant kSecCodeInfoIdentifier A CFString with the actual signing identifier
 372                 sealed into the signature. Absent for unsigned code.
 373         @constant kSecCodeInfoImplicitDesignatedRequirement A SecRequirement describing
 374                 the designated requirement that the system did generate, or would have generated,
 375                 for the code. If the Designated Requirement was implicitly generated, this is
 376                 the same object as kSecCodeInfoDesignatedRequirement; this can be used to test
 377                 for an explicit Designated Requirement.
 378         @constant kSecCodeInfoMainExecutable A CFURL identifying the main executable file
 379                 of the code. For single files, that is the file itself. For bundles, it is the
 380                 main executable as identified by its Info.plist.
 381         @constant kSecCodeInfoPList A retained CFDictionary referring to the secured Info.plist
 382                 as seen by code signing. Absent if no Info.plist is known to the code signing
 383                 subsystem. Note that this is not the same dictionary as the one CFBundle would
 384                 give you (CFBundle is free to add entries to the on-disk plist).
 385         @constant kSecCodeInfoRequirements A CFString describing the internal requirements
 386                 of the code in canonical syntax.
 387         @constant kSecCodeInfoRequirementsData A CFData containing the internal requirements
 388                 of the code as a binary blob.
 389         @constant kSecCodeInfoSource A CFString describing the source of the code signature
 390                 used for the code object. The values are meant to be shown in informational
 391                 displays; do not rely on the precise value returned.
 392         @constant kSecCodeInfoStatus A CFNumber containing the dynamic status word of the
 393                 (running) code. This is a snapshot at the time the API is executed and may be
 394                 out of date by the time you examine it. Do note however that most of the bits
 395                 are sticky and thus some values are permanently reliable. Be careful.
 396         @constant kSecCodeInfoTime A CFDate describing the signing date (securely) embedded
 397                 in the code signature. Note that a signer is able to omit this date or pre-date
 398                 it. Nobody certifies that this was really the date the code was signed; however,
 399                 you do know that this is the date the signer wanted you to see.
 400                 Ad-hoc signatures have no CMS and thus never have secured signing dates.
 401         @constant kSecCodeInfoTimestamp A CFDate describing the signing date as (securely)
 402                 certified by a timestamp authority service. This time cannot be falsified by the
 403                 signer; you trust the timestamp authority's word on this.
 404                 Ad-hoc signatures have no CMS and thus never have secured signing dates.
 405         @constant kSecCodeInfoTrust The (retained) SecTrust object the system uses to
 406                 evaluate the validity of the code's signature. You may use the SecTrust API
 407                 to extract detailed information, particularly for reasons why certificate
 408                 validation may have failed. This object may continue to be used for further
 409                 evaluations of this code; if you make any changes to it, behavior is undefined.
 410         @constant kSecCodeInfoUnique A CFData binary identifier that uniquely identifies
 411                 the static code in question. It can be used to recognize this particular code
 412                 (and none other) now or in the future. Compare to kSecCodeInfoIdentifier, which
 413                 remains stable across (developer-approved) updates.
 414                 The algorithm used may change from time to time. However, for any existing signature,
 415                 the value is stable.
 416         @constant kSecCodeInfoCdHashes An array containing the values of the kSecCodeInfoUnique
 417         binary identifier for every digest algorithm supported in the signature, in the same
 418         order as in the kSecCodeInfoDigestAlgorithms array. The kSecCodeInfoUnique value
 419         will be contained in this array, and be the one corresponding to the
 420         kSecCodeInfoDigestAlgorithm value.
