This is the corecrypto (cc) project.
The main goal is to provide low level fast math routines and crypto APIs which
can be used in various environments (Kernel, bootloader, userspace, etc.). It
is an explicit goal to minimize dependancies between modules and functions so
that clients of this library only end up with the routines they need and
nothing more.
Current corecrypto consists of the following submodules:
cc Headers and code common to all of the modules
ccasn1 ASN.1 typeid constants and ccoid definition.
cccurve25519 Curve25519 Diffie-Hellman routines.
ccder DER encoding decoding support
ccn Math on vectors of n cc_units
cczp Math over a prime field on vectors of n cc_units
ccz Variable sized signed integer math routines
ccdrbg Deterministic Random Byte Generators
ccrng Random Bytes Generators
ccdh Diffie-Hellman routines.
cced25519 Ed25519 signature routines.
ccrsa RSA routines.
ccec Eliptic Curve Curves, ec specific math and APIs
ccdigest Digest abstraction layer.
cchmac HMAC using any ccdigest.
ccpbkdf2 PKKDF2 using any ccdigest.
ccmd2 MD2 digest implementations.
ccmd4 MD4 digest implementations.
ccmd5 MD5 digest implementations.
ccripemd RIPE-MD digest implementations.
ccsha1 SHA-1 digest implementations.
ccsha2 SHA-2 digest implementations.
ccmode Symmetric cipher chaining mode interfaces.
ccpad Symmetric cipher padding code.
ccaes AES symmetric cipher implementations.
ccblowfish Blowfish symmetric cipher implementations.
cccast Cast symmetric cipher implementations.
ccdes DES and 3DES symmetric cipher implementations.
ccrc2 RC2 symmetric cipher implementations.
ccrc4 RC4 symmetric cipher implementations.
ccperf Performance testing harness.
cctest Common utilities for creating self tests and XCunit tests.
Each module has the following subdirectories:
corecrypto headers for this module
src sources for this module
doc documentation, references, etc.
xcunit XCTest based unit tests for this module.
crypto_tests sources for executable tests for this module
test_vectors test vectors for this module
tools sources for random helper tools.
The following subdirections don't follow the module layout yet:
corecrypto_kext Supporting files for kernel extension build and fips support.
corecrypto_dylib Supporting files for userspace shared lib build and fips support.
