Unambiguously digest structured data
udigest
provides utilities for unambiguous hashing the structured data. Structured
data can be anything that implements Digestable
trait:
str
,String
,CStr
,CString
- Integers:
i8
,i16
,i32
,i64
,i128
,u8
,u16
,u32
,u64
,u128
,char
,isize
,usize
- Containers:
Box
,Arc
,Rc
,Cow
,Option
,Result
- Collections: arrays, slices,
Vec
,LinkedList
,VecDeque
,BTreeSet
,BTreeMap
The trait is intentionally not implemented for certain types:
HashMap
,HashSet
as they can not be traversed in deterministic order
The Digestable
trait can be implemented for the struct using a macro:
#[derive(udigest::Digestable)]
struct Person {
name: String,
job_title: String,
}
let alice = Person {
name: "Alice".into(),
job_title: "cryptographer".into(),
};
let hash = udigest::hash::<sha2::Sha256>(&alice);
The crate intentionally does not try to follow any existing standards for unambiguous
encoding. The format for encoding was designed specifically for udigest
to provide
a better usage experience in Rust. The details of encoding format can be found in
encoding
module.
Features
digest
enables support of hash functions that implementdigest
traits
If feature is not enabled, the crate is still usable viaDigestable
