/*!
+ The following CFString constants can be used as keys in the parameters argument
+ of SecCodeSignerCreate to specify various modes and options of the signing operation.
+ Passing any keys not specified here may lead to undefined behavior and is not supported.
+ The same applies to passing objects of types not explicitly allowed here.
+
+ @constant kSecCodeSignerDetached Determines where the signature is written.
+ If this key is absent, the code being signed is modified to contain the signature,
+ replacing any signature already embedded there.
+ If the value is kCFNull, the signature is written to the system-wide detached
+ signature database. (You must have root privileges to write there.)
+ If the value of this key is a CFURL, the signature is written to a file at that location,
+ replacing any data there.
+ If the value is a CFMutableData, the signature is appended to that data.
+ @constant kSecCodeSignerDryRun A boolean value. If present and true, the actual writing
+ of the signature is inhibited, and the code is not modified, but all operations
+ leading up to this are performed normally, including the cryptographic access to
+ the signing identity (if any).
+ @constant kSecCodeSignerFlags A CFNumber specifying which flags to set in the code signature.
+ Note that depending on circumstances, this value may be augmented or modified
+ as part of the signing operation.
+ @constant kSecCodeSignerIdentifier If present, a CFString that explicitly specifies
+ the unique identifier string sealed into the code signature. If absent, the identifier
+ is derived implicitly from the code being signed.
+ @constant kSecCodeSignerIdentifierPrefix If the unique identifier string of the code signature
+ is implicitly generated, and the resulting string does not contain any "." (dot)
+ characters, then the (string) value of this parameter is prepended to the identifier.
+ By convention, the prefix is usually of the form "com.yourcompany.", but any value
+ is acceptable. If the kSecCodeSignerIdentifier parameter is specified, this parameter
+ is ineffective (but still allowed).
@constant kSecCodeSignerIdentity A SecIdentityRef describing the signing identity
- to use for signing code. This is a mandatory parameter.
- @constant kSecCodeSignerDetached If present, a detached code signature is generated.
- If absent, code signature data is written into the target code (which must
- be writable). The value is a CFURL identifying the file that is replaced with
- the detached signature data.
- @constant kSecCodeSignerRequirements Internal code requirements.
- @constant kSecCodeSignerFlags Signature flags.
+ to use for signing code. This is a mandatory parameter for signing operations.
+ Its value must be either a SecIdentityRef specifying a cryptographic identity
+ valid for Code Signing, or the special value kCFNull to indicate ad-hoc signing.
+ @constant kSecCodeSignerOperation The type of operation to be performed. Valid values
+ are kSecCodeSignerOperationSign to sign code, and kSecCodeSignerOperationRemove
+ to remove any existing signature from code. The default operation is to sign code.
+ @constant kSecCodeSignerPageSize An integer value explicitly specifying the page size
+ used to sign the main executable. This must be a power of two. A value of zero indicates
+ infinite size (no paging).
+ Only certain page sizes are allowed in most circumstances, and specifying an inappropriate
+ size will lead to spurious verification failures. This is for expert use only.
+ @constant kSecCodeSignerRequirements Specifies the internal requirements to be sealed into
+ the code signature. Must be either a CFData containing the binary (compiled) form of
+ a requirements set (SuperBlob), or a CFString containing a valid text form to be
+ compiled into binary form. Default requirements are automatically generated if this
+ parameter is omitted, and defaults may be applied to particular requirement types
+ that are not specified; but any requirement type you specify is sealed exactly as
+ specified.
+ @constant kSecCodeSignerResourceRules A CFDictionary containing resource scanning rules
+ determining what resource files are sealed into the signature (and in what way).
+ A situation-dependent default is applied if this parameter is not specified.
+ @constant kSecCodeSignerSDKRoot A CFURLRef indicating an alterate directory root
+ where signing operations should find subcomponents (libraries, frameworks, modules, etc.).
+ The default is the host system root "/".
+ @constant kSecCodeSignerSigningTime Specifies what date and time is sealed into the
+ code signature's CMS data. Can be either a CFDate object specifying a date, or
+ the value kCFNull indicating that no date should be included in the signature.
+ If not specified, the current date is chosen and sealed.
+ Since an ad-hoc signature has no CMS data, this argument is ineffective
+ for ad-hoc signing operations.
