Crate solana_nostd_sha256 

A more efficient, no_std SHA-256 for the Solana SVM.

On target_os = "solana", hashing routes through the sol_sha256 syscall. Off-Solana, it falls through to the sha2 crate so the same APIs work in host code (tests, off-chain tooling). The Solana implementation costs ~100 CUs for hashv(&[b"test"]), vs ~120 CUs for solana_program::hash::hashv.

Constants

HASH_LENGTH

Length of a SHA-256 digest, in bytes.

Functions

hash

Hash a single byte slice and return the digest by value.

hash_into

Hash data directly into the provided 32-byte buffer.

hash_ref

Hash any T: AsRef<[u8]> (e.g. &str, &[u8; N]) and return the digest.

hashv

Hash a sequence of byte slices as if they were concatenated, and return the digest. Cheaper than concatenating the inputs yourself.
