This source reference follows declared modules and preserves feature attributes. It includes public declarations and implementation methods in those modules. Private-module exports and trait resolution still require the compiler; not every declaration is a crate-root import. Function bodies and constant values are omitted. Source comments describe their implementation context and are not a production deployment claim.

ct::ct_eq

Returns true iff a and b have the same length and identical contents.

Comparison is constant time with respect to slice length: the entire a slice is consumed before returning. Use this for comparing secrets, MAC tags, and any byte sequence whose contents must not leak via timing.

Examples

use openagent_crypto_wasm::ct::ct_eq;
assert!(ct_eq(b"abc", b"abc"));
assert!(!ct_eq(b"abc", b"abd"));
assert!(!ct_eq(b"abc", b"abcd"));

pub fn ct_eq(a: &[u8], b: &[u8]) -> bool;

Source line: 28.

ct::fill_random

Fills out with cryptographically secure random bytes.

On native targets this calls getrandom::getrandom which delegates to the OS CSPRNG (/dev/urandom, getrandom(2), BCryptGenRandom, etc.). On WebAssembly with the wasm feature enabled, the same call routes through the JS host's crypto.getRandomValues.

Errors

[CryptoError::RngFailed] if the underlying CSPRNG returns an error (extremely rare; usually only on misconfigured WASI environments).

pub fn fill_random(out: &mut [u8]) -> Result<(), CryptoError>;

Source line: 46.

ct::random_bytes

Returns n cryptographically secure random bytes.

pub fn random_bytes(n: usize) -> Result<Vec<u8>, CryptoError>;

Source line: 53.
