README
webbuf_sha256
SHA-256 hash and HMAC-SHA256 for Rust and WebAssembly.
Installation
[dependencies]
webbuf_sha256 = "0.13"
Usage
use webbuf_sha256::{sha256_hash, double_sha256_hash, sha256_hmac};
// SHA-256 hash
let data = b"abc";
let hash = sha256_hash(data).unwrap();
assert_eq!(
hex::encode(&hash),
"ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad"
);
// Double SHA-256 (used in Bitcoin)
let double_hash = double_sha256_hash(data).unwrap();
assert_eq!(double_hash.len(), 32);
// HMAC-SHA256
let key = b"secret key";
let message = b"message";
let mac = sha256_hmac(key, message).unwrap();
assert_eq!(mac.len(), 32);
API
| Function | Description |
|---|---|
sha256_hash(data: &[u8]) -> Result<Vec<u8>, String> |
Compute SHA-256 hash (32 bytes) |
double_sha256_hash(data: &[u8]) -> Result<Vec<u8>, String> |
Compute SHA-256(SHA-256(data)) |
sha256_hmac(key: &[u8], data: &[u8]) -> Result<Vec<u8>, String> |
Compute HMAC-SHA256 |
WebAssembly
Build with the wasm feature for WebAssembly support:
[dependencies]
webbuf_sha256 = { version = "0.13", features = ["wasm"] }
The TypeScript wrapper is available as @webbuf/sha256 on npm.
