apple/corecrypto

corecrypto is a low-level cryptographic library used by Apple security frameworks and intended for varied environments, not a direct app-facing API. A typical use begins when a framework requests a cryptographic operation; the corresponding module performs it and returns bytes, keys, or a verification result. The repository includes symmetric and asymmetric cryptography, hashing, derivation and randomness, encoding, post-quantum algorithms, and FIPS self-tests. The README documents these capabilities and intended use; sampled source is limited, so detailed calls between algorithm modules are not inferred.
