NCode.Buffers

CI Coverage Target framework License

Pinned, pooled .NET buffers that zero themselves on dispose, for keys and other secrets, plus fixed-size buffer writers and string splitting without substring copies.

Installation

dotnet add package NCode.Buffers

The target frameworks are the ones the package's .csproj declares; they are listed on nuget.org's Frameworks tab and shown by the badge above. CHANGELOG.md records when a framework is added or dropped and which release line to stay on. The package depends on Nerdbank.Streams, whose Sequence<T> the pooled buffer writers return.

Example

This example derives a key from a password, verifies an HMAC-SHA256 signature with it, and zeroes the derived key and the expected MAC when the method returns.

using System.Security.Cryptography;
using NCode.Buffers;

public static class Signatures
{
    public static bool VerifySignature(
        ReadOnlySpan<byte> password,
        ReadOnlySpan<byte> salt,
        ReadOnlySpan<byte> payload,
        ReadOnlySpan<byte> signature
    )
    {
        // A pinned, pooled 32-byte key, zeroed when keyOwner is disposed.
        using var keyOwner = BufferFactory.Rent(32, isSensitive: true, out Span<byte> key);
        Rfc2898DeriveBytes.Pbkdf2(
            password,
            salt,
            key,
            iterations: 600_000,
            HashAlgorithmName.SHA256
        );

        // The expected MAC lives on the stack and is zeroed when expectedLifetime is disposed.
        Span<byte> expected = stackalloc byte[HMACSHA256.HashSizeInBytes];
        using var expectedLifetime = expected.GetSecureLifetime();
        HMACSHA256.HashData(key, payload, expected);

        // Constant time, so the comparison doesn't reveal where the MACs differ.
        return CryptographicOperations.FixedTimeEquals(expected, signature);
    }
}
