NCode.Base64Url 1.1.2

Overview

This library provides methods for encoding and decoding base64url (RFC 4648) data using the new memory efficient Span and Buffer APIs.

namespace NCode.Encoders;

public static class Base64Url
{
    // Encode...

    public static int GetCharCountForEncode(
        int byteCount);

    public static string Encode(
        ReadOnlySpan<byte> bytes);

    public static int Encode(
        ReadOnlySpan<byte> bytes,
        IBufferWriter<char> writer);

    public static int Encode(
        ReadOnlySequence<byte> sequence,
        IBufferWriter<char> writer);

    public static bool TryEncode(
        ReadOnlySequence<byte> sequence,
        Span<char> chars,
        out int charsWritten);

    public static bool TryEncode(
        ReadOnlySpan<byte> bytes,
        Span<char> chars,
        out int charsWritten);

    // Decode...

    public static int GetByteCountForDecode(
        int charCount);

    public static byte[] Decode(
        ReadOnlySpan<char> chars);

    public static int Decode(
        ReadOnlySpan<char> chars,
        IBufferWriter<byte> writer);

    public static int Decode(
        ReadOnlySequence<char> sequence,
        IBufferWriter<byte> writer);

    public static bool TryDecode(
        ReadOnlySequence<char> sequence,
        Span<byte> bytes,
        out int bytesWritten);

    public static bool TryDecode(
