Allocation-conscious SHA-256, ASCII comparison, and content-sniffing helpers for ReadOnlySpan<byte>.

Installation

dotnet add package Soenneker.Extensions.Spans.Readonly.Bytes

SHA-256 as hexadecimal text

using Soenneker.Extensions.Spans.Readonly.Bytes;

ReadOnlySpan<byte> data = "payload"u8;

string upper = data.ToSha256Hex();
string lower = data.ToSha256Hex(upperCase: false);

Span<char> destination = stackalloc char[64];
bool written = data.TryWriteSha256Hex(destination, upperCase: false, out int charsWritten);

ToSha256Hex() returns exactly 64 characters. TryWriteSha256Hex() avoids the result-string allocation, requires a destination of at least 64 characters, and reports charsWritten = 0 without modifying the destination when it is too small.

Classify an unknown payload

using Soenneker.Enums.ContentKinds;
using Soenneker.Extensions.Spans.Readonly.Bytes;

ReadOnlySpan<byte> payload = "  {\"id\": 42}"u8;

ContentKind kind = payload.Classify();
bool looksLikeJson = payload.LooksLikeJson();

Classification is deliberately a cheap sniff, not parsing or validation. It examines at most the first 512 bytes, skips a leading UTF-8 BOM, treats a null byte or a high density of control bytes as binary, and otherwise uses the first non-whitespace byte to choose JSON, XML/HTML, or text. JSON scalar prefixes such as a quote, digit, -, t, f, or n are recognized.

Use a real JSON/XML parser before trusting or processing untrusted content. UTF-8 validity is not checked, and XmlOrHtml does not distinguish the two formats.

ASCII helpers

bool equal = "CONTENT-TYPE"u8.Utf8AsciiEqualsIgnoreCase("content-type"u8);
bool containsUtf8 = "café"u8.ContainsNonAscii();

Utf8AsciiEqualsIgnoreCase() compares ASCII letters without culture rules. It does not validate that either input is ASCII; non-letter bytes must match exactly. ContainsNonAscii() simply detects bytes from 0x80 through 0xFF and does not validate UTF-8.
