Expand description

Represents Apple’s common embedded code signature data structures.

This type represents a lightly parsed SuperBlob with CodeSigningMagic::EmbeddedSignature. It is the most common embedded signature data format you are likely to encounter.

Fields

magic: CodeSigningMagic

Magic value from header.

length: u32

Length of this super blob.

count: u32

Number of blobs in this super blob.

data: &'a [u8]

Raw data backing this super blob.

blobs: Vec<BlobEntry<'a>>

All the blobs within this super blob.

Implementations

source

impl<'a> EmbeddedSignature<'a>

source

pub fn from_bytes(data: &'a [u8 ]) -> Result<Self, AppleCodesignError>

Attempt to parse an embedded signature super blob from data.

The argument to this function is likely the subset of the __LINKEDIT Mach-O section that the LC_CODE_SIGNATURE load instructions points it.

source

pub fn find_slot(&self, slot: CodeSigningSlot) -> Option<&BlobEntry<'a>>

Find the first occurrence of the specified slot.

source

pub fn find_slot_parsed(
&self,
slot: CodeSigningSlot
) -> Result<Option<ParsedBlob<'a>>, AppleCodesignError>

source

pub fn code_directory(
&self
) -> Result<Option<Box<CodeDirectoryBlob<'a>>>, AppleCodesignError>

Attempt to resolve the primary CodeDirectoryBlob for this signature data.

Returns Err on data parsing error or if the blob slot didn’t contain a code directory.

Returns Ok(None) if there is no code directory slot.

source

pub fn alternate_code_directories(
&self
) -> Result<Vec<(CodeSigningSlot, Box<CodeDirectoryBlob<'a>>)>, AppleCodesignError>

Obtain code directories occupying alternative slots.

Embedded signatures set aside a few slots for alternate code directory data structures. This method will resolve any that are present.

source

pub fn all_code_directories(
&self
) -> Result<Vec<(CodeSigningSlot, Box<CodeDirectoryBlob<'a>>)>, AppleCodesignError>

Resolve all code directories in this signature.

source

pub fn code_directory_for_digest(
&self,
digest: DigestType
) -> Result<Option<Box<CodeDirectoryBlob<'a>>>, AppleCodesignError>

Attempt to resolve a code directory containing digests of the specified type.

source

pub fn entitlements(
&self
) -> Result<Option<Box<EntitlementsBlob<'a>>>, AppleCodesignError>

Attempt to resolve a parsed EntitlementsBlob for this signature data.

Returns Err on data parsing error or if the blob slot didn’t contain an entitlments blob.

Returns Ok(None) if there is no entitlements slot.

source

pub fn code_requirements(
&self
) -> Result<Option<Box<RequirementSetBlob<'a>>>, AppleCodesignError>

Attempt to resolve a parsed RequirementSetBlob for this signature data.

Returns Err on data parsing error or if the blob slot didn’t contain a requirements blob.

Returns Ok(None) if there is no requirements slot.

source

pub fn signature_data(&self) -> Result<Option<&'a [u8 ]>, AppleCodesignError>

Attempt to resolve raw CMS signature data.

The returned data is likely DER PKCS#7 with the root object pkcs7-signedData (1.2.840.113549.1.7.2).

source

pub fn signed_data(&self) -> Result<Option<SignedData>, AppleCodesignError>

Obtain the parsed CMS SignedData.
