+; NOTE(flysand): The function call to __chkstk is called
+; by the compiler, when we're allocating arrays larger than
+; a page size. The reason is because the OS doesn't map the
+; whole stack into memory all at once, but does so page-by-page.
+; When the next page is touched, the CPU generates a page fault,
+; which *the OS* is handling by allocating the next page in the
+; stack until we reach the limit of stack size.
+;
+; This page is called the guard page, touching it will extend
+; the size of the stack and overwrite the stack limit in the TEB.
+;
+; If we allocate a large enough array and start writing from the
+; bottom of it, it's possible that we may start touching
+; non-contiguous pages which are unmapped. OS only maps the stack
+; page into the memory if the page above it was also mapped.
+;
+; Therefore the compilers insert this routine, the sole purpose
+; of which is to step through the stack starting from the RSP
+; down to the new RSP after allocation, and touch every page
+; of the new allocation so that the stack is fully mapped for
+; the new allocation
+;
+; I've gotten this code by disassembling the output of MSVC long
+; time ago. I don't remember if I've cleaned it up, but it definately
+; stinks.
+;
+; Additional notes:
+;   RAX (passed as parameter) holds the allocation's size
+;   GS:[0x10] references the current stack limit
+;     (i.e. bottom of the stack (i.e. lowest address accessible))
+;
+; Also this stuff is windows-only kind of thing, because linux people
+; didn't think stack that grows is cool enough for them, but the kernel
+; totally supports this kind of stack.

-#### High level API
+## Implementation considerations
-Each hash algorithm contains a procedure group named `hash`, or if the algorithm provides more than one digest size `hash_<size>`\*.  
-Included in these groups are six procedures.
-* `hash_string` - Hash a given string and return the computed hash. Just calls `hash_bytes` internally
-* `hash_bytes` - Hash a given byte slice and return the computed hash
-* `hash_string_to_buffer` - Hash a given string and put the computed hash in the second proc parameter. Just calls `hash_bytes_to_buffer` internally
-* `hash_bytes_to_buffer` - Hash a given string and put the computed hash in the second proc parameter. The destination buffer has to be at least as big as the digest size of the hash
-* `hash_stream` - Takes a stream from io.Stream and returns the computed hash from it
-* `hash_file` - Takes a file handle and returns the computed hash from it. A second optional boolean parameter controls if the file is streamed (this is the default) or read at once (set to true)
 
-\* On some algorithms there is another part to the name, since they might offer control about additional parameters.  
+- The crypto packages are not thread-safe.
-For instance, `HAVAL` offers different sizes as well as three different round amounts.  
+- Best-effort is make to mitigate timing side-channels on reasonable
-Computing a 256-bit hash with 3 rounds is therefore achieved by calling `haval.hash_256_3(...)`.
+  architectures.  Architectures that are known to be unreasonable include
+  but are not limited to i386, i486, and WebAssembly.
+- The packages attempt to santize sensitive data, however this is, and
+  will remain a "best-effort" implementation decision.  As Thomas Pornin
+  puts it "In general, such memory cleansing is a fool's quest."
+- All of these packages have not received independent third party review.
 
-#### Low level API
+## License
-The above mentioned procedures internally call three procedures: `init`, `update` and `final`.
-You may also directly call them, if you wish.
 
-#### Example
-```odin
-package crypto_example
-
-// Import the desired package
-import "core:crypto/md4"
-
-main :: proc() {
-    input := "foo"
-
-    // Compute the hash, using the high level API
-    computed_hash := md4.hash(input)
-
-    // Variant that takes a destination buffer, instead of returning the computed hash
-    hash := make([]byte, md4.DIGEST_SIZE) // @note: Destination buffer has to be at least as big as the digest size of the hash
-    md4.hash(input, hash[:])
-
-    // Compute the hash, using the low level API
-    ctx: md4.Md4_Context
-    computed_hash_low: [16]byte
-    md4.init(&ctx)
-    md4.update(&ctx, transmute([]byte)input)
-    md4.final(&ctx, computed_hash_low[:])
-}
-```
-For example uses of all available algorithms, please see the tests within `tests/core/crypto`.
-
-#### Thread safety
-The crypto package is not thread-safe at the moment. This may change in the future.
-
-### Disclaimer
-The algorithms were ported out of curiosity and due to interest in the field.
-We have not had any of the code verified by a third party or tested/fuzzed by any automatic means.
-Wherever we were able to find official test vectors, those were used to verify the implementation.
-We do not recommend using them in a production environment, without any additional testing and/or verification.
-
-### ToDo
-* Ciphers (Symmetric, Asymmetric)
-* MACs (Message Authentication Code)
-* CSPRNGs (Cryptographically Secure PseudoRandom Number Generator)
-* KDFs (Key Derivation Function)
-* KEAs (Key Exchange Algorithm)
-

+package hash provides a generic interface to the supported hash algorithms.
+
+A high-level convenience procedure group `hash` is provided to easily
+accomplish common tasks.
+- `hash_string` - Hash a given string and return the digest.
+- `hash_bytes` - Hash a given byte slice and return the digest.
+- `hash_string_to_buffer` - Hash a given string and put the digest in
+  the third parameter.  It requires that the destination buffer
+  is at least as big as the digest size.
+- `hash_bytes_to_buffer` - Hash a given string and put the computed
+  digest in the third parameter.  It requires that the destination
+  buffer is at least as big as the digest size.
+- `hash_stream` - Incrementally fully consume a `io.Stream`, and return
+  the computed digest.
+- `hash_file` - Takes a file handle and returns the computed digest.
+  A third optional boolean parameter controls if the file is streamed
+  (default), or or read at once.
+
+```odin
+package hash_example
+
+import "core:crypto/hash"
+
+main :: proc() {
+	input := "Feed the fire."
+
+	// Compute the digest, using the high level API.
+	returned_digest := hash.hash(hash.Algorithm.SHA512_256, input)
+	defer delete(returned_digest)
+
+	// Variant that takes a destination buffer, instead of returning
+	// the digest.
+	digest := make([]byte, hash.DIGEST_SIZES[hash.Algorithm.BLAKE2B]) // @note: Destination buffer has to be at least as big as the digest size of the hash.
+	defer delete(digest)
+	hash.hash(hash.Algorithm.BLAKE2B, input, digest)
+}
+```
+
+A generic low level API is provided supporting the init/update/final interface
+that is typical with cryptographic hash function implementations.
+
+```odin
+package hash_example
+
+import "core:crypto/hash"
+
+main :: proc() {
