File-Raw-Hash

A File::Raw plugin that computes cryptographic and integrity digests
of file contents in the same pass File::Raw is already making. The
bytes flow through unchanged; the digest is delivered via a caller-
supplied scalar or hash reference.

    use File::Raw qw(import);
    use File::Raw::Hash;

    # Single algorithm, scalar destination.
    my $bytes = file_slurp("input.bin",
        plugin => 'hash', algo => 'sha256', into => \my $digest);

    # Multiple algorithms in one pass.
    my %digests;
    file_slurp("input.bin",
        plugin => 'hash',
        algos  => [qw(sha256 md5 crc32)],
        into   => \%digests);

    # Streaming: each_line digests the file in chunks; RAM stays
    # bounded regardless of file size.
    each_line("huge.log", sub { ... },
        plugin => 'hash', algo => 'sha256', into => \my $d);

ALGORITHMS

    sha256, sha512, sha1, md5, crc32, xxh64, blake3

HMAC

    Pass hmac_key => $key to switch sha256/sha512/sha1/md5 into RFC
    2104 HMAC mode. crc32, xxh64, and blake3 reject hmac_key with a
    named error.

OUTPUT FORMATS

    hex (default), HEX, base64, base64url, raw

DEPENDENCIES

    File::Raw 0.11+. No external library dependency: every algorithm
    is a vendored, public-domain reference implementation. Builds
    against any C99 compiler; no OpenSSL, no libsodium.

INSTALLATION
