Yawning Angel	44758f2a60	core/crypto: Stop using context.temp_allocator ... The max digest size for the foreseeable future will be 512 bits, and the max block size is currently 1152 bits (SHA3-224). If people add more exotic hash algorithms without bumping the constants when required, tests will fail. The stream buffer will currently be 576 bytes, which is "fine" to just stick on the stack, and is a sensible multiple of the more common block size of 64 bytes.	2024-02-07 02:33:53 +09:00
Yawning Angel	2357293e05	core/crypto/hash: Make the low level interface allocator-less ... Just (ab)using reflect to victory is probably fine.	2024-02-07 00:37:18 +09:00
Yawning Angel	7a8b1669b0	core/crypto: Expose the block sizes for every hash algorithm ... While I just went and made this private, this information is required for keying HMAC.	2024-02-07 00:37:18 +09:00
Yawning Angel	00ab3beed9	core:crypto/hash: Add a generic higher level hash interface ... There is a lot of code duplicated in convenience methods in each hash implementation, and having a generic hash type makes implementing higher-level constructs such as HMAC significantly easier down the road.	2024-02-07 00:37:18 +09:00
