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 four procedures.
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)

# fiat
This package contains low level arithmetic required to implement certain
cryptographic primitives, ported from the [fiat-crypto project][1]
along with some higher-level helpers.
## Notes
fiat-crypto gives the choice of 3 licenses for derived works. The 1-Clause
BSD license is chosen as it is compatible with Odin's existing licensing.
The routines are intended to be timing-safe, as long as the underlying
integer arithmetic is constant time. This is true on most systems commonly
used today, with the notable exception of WASM.
While fiat-crypto provides both output targeting both 32-bit and 64-bit
architectures, only the 64-bit versions were used, as 32-bit architectures
are becoming increasingly uncommon and irrelevant.
With the current Odin syntax, the Go output is trivially ported in most
cases and was used as the basis of the port.
In the future, it would be better to auto-generate Odin either directly
by adding an appropriate code-gen backend written in Coq, or perhaps by
parsing the JSON output.
As this is a port rather than autogenerated output, none of fiat-crypto's
formal verification guarantees apply, unless it is possible to prove binary
equivalence.
For the most part, alterations to the base fiat-crypto generated code was
kept to a minimum, to aid auditability. This results in a somewhat
ideosyncratic style, and in some cases minor performance penalties.

/*
Package endian implements sa simple translation between bytes and numbers with
specific endian encodings.
buf: [100]u8
put_u16(buf[:], .Little, 16) or_return
You may ask yourself, why isn't `byte_order` platform Endianness by default, so we can write:
put_u16(buf[:], 16) or_return
The answer is that very few file formats are written in native/platform endianness. Most of them specify the endianness of
each of their fields, or use a header field which specifies it for the entire file.
e.g. a file which specifies it at the top for all fields could do this:
file_order := .Little if buf[0] == 0 else .Big
field := get_u16(buf[1:], file_order) or_return
If on the other hand a field is *always* Big-Endian, you're wise to explicitly state it for the benefit of the reader,
be that your future self or someone else.
field := get_u16(buf[:], .Big) or_return
