base2048 - Binary encoding optimised for Twitter

•    Javascript

---

Base2048 is a binary encoding optimised for transmitting data through Twitter. This JavaScript module, base2048, is the first implementation of this encoding. Using Base2048, up to 385 octets can fit in a single Tweet. Compare with Base65536, which manages only 280 octets. * A Tweet can be up to 280 Unicode characters, give or take Twitter's complex "weighting" calculation. † Base85 is listed for completeness but all variants use characters which are considered hazardous for general use in text: escape characters, brackets, punctuation etc.. ‡ Base131072 is a work in progress, not yet ready for general use.

base64-js - Base64 encoding/decoding in pure JS

•    Javascript

---

base64-js does basic base64 encoding/decoding in pure JS. Many browsers already have base64 encoding/decoding functionality, but it is for text data, not all-purpose binary data.

text-encoding - Polyfill for the Encoding Living Standard's API

•    Javascript

---

This is a polyfill for the Encoding Living Standard API for the Web, allowing encoding and decoding of textual data to and from Typed Array buffers for binary data in JavaScript. By default it adheres to the spec and does not support encoding to legacy encodings, only decoding. It is also implemented to match the specification's algorithms, rather than for performance. The intended use is within Web pages, so it has no dependency on server frameworks or particular module schemes.

CyoEncode

•    C

---

Provides C functions for encoding binary data into a printable representation using base64, base32, or base16 (hex) character sets, plus equivalent functions for the decoding of such encoded data back into its binary form.

base64 - A robust base64 encoder/decoder that is fully compatible with `atob()` and btoa()`, written in JavaScript

•    Javascript

---

base64 is a robust base64 encoder/decoder that is fully compatible with atob() and btoa(), written in JavaScript. The base64-encoding and -decoding algorithms it uses are fully RFC 4648 compliant.A string representing the semantic version number.

pbf - A low-level, lightweight protocol buffers implementation in JavaScript.

•    Javascript

---

A low-level, fast, ultra-lightweight (3KB gzipped) JavaScript library for decoding and encoding protocol buffers, a compact binary format for structured data serialization. Works both in Node and the browser. Supports lazy decoding and detailed customization of the reading/writing code.If you use webpack as your module bundler, you can use pbf-loader to load .proto files directly. It returns a compiled module ready to be used.

Libb64

•    

---

libb64 is a library of ANSI C routines for fast encoding/decoding data into and from a base64-encoded format. C++ wrappers are included, as well as the source code for standalone encoding and decoding executables.

Simple Binary Encoding - Simple Binary Encoding (SBE) - High Performance Message Codec

•    Java

---

SBE is an OSI layer 6 presentation for encoding and decoding binary application messages for low-latency financial applications. This repository contains the reference implementations in Java, C++, Golang, and C#. The Java and C++ SBE implementations are designed with work very efficiently with the Aeron messaging system for low-latency and high-throughput communications. The Java SBE implementation has a dependency on Agrona for its buffer implementations.

Ecoji - Encodes (and decodes) data as emojis

•    Go

---

Ecoji encodes data as 1024 emojis, its base1024 with an emoji character set. As a bonus, includes code to decode emojis to original data. The difference between Ecoji and Base64 is that Ecoji is more bytes, but less visible characters. With Ecoji each visible char represents 10 bits, but each character is multi-byte. With base64 each char represents 6 bits and is one byte.

libbinxml

•    C

---

The BINXML library was create to fill the need for an efficient way to embed binary data inside xml files. It provides routines for encoding and decoding binary files into valid UTF-16 text files that can be embedded inside XML files.

Decodify - Detect and decode encoded strings, recursively.

•    Python

---

Boom! Thats what Decodify does. It automatically detects the encoding and decodes it and it does that recursively. Warning: Decodify uses third party web services for MD5, SHA1 & SHA2 hash lookups. If you are dealing with sensitive data, you are advised to use the -s option which will prevent Decodify to use these services.

scodec - Scala combinator library for working with binary data

•    Scala

---

Scala combinator library for working with binary data. As a result, the library is implemented as a combinator based DSL. Performance is considered but yields to the above design constraints.

CyberChef - The Cyber Swiss Army Knife for Developers (DevToolbox)

•    Javascript

---

CyberChef is a simple, intuitive web app for carrying out all manner of "cyber" operations within a web browser. These operations include simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more.

webauthn-json - 🔏 A small WebAuthn API wrapper that translates to/from pure JSON using base64url.

•    TypeScript

---

@github/webauthn-json is a client-side Javascript library that serves as convenience wrapper for the the WebAuthn API by encoding binary data using base64url (also known as "websafe" or "urlsafe" base64). The WebAuthn API itself takes input and output values that look almost like JSON, except that binary data is represented as ArrayBuffers. Using webauthn-json allows the data to be sent from/to the server as normal JSON without any custom client-side processing.

ApacheDS - Apache Directory Project

•    Java

---

ApacheDS is an embeddable directory server entirely written in Java, which has been certified LDAPv3 compatible by the Open Group. Besides LDAP it supports Kerberos 5 and the Change Password Protocol. It has been designed to introduce triggers, stored procedures, queues and views to the world of LDAP which has lacked these rich constructs.

Utf8Json - Definitely Fastest and Zero Allocation JSON Serializer for C#(NET,

•    CSharp

---

Definitely Fastest and Zero Allocation JSON Serializer for C#(.NET, .NET Core, Unity and Xamarin), this serializer write/read directly to UTF8 binary so boostup performance. And I adopt the same architecture as the fastest binary serializer, MessagePack for C# that I've developed.This benchmark is convert object to UTF8 and UTF8 to object benchmark. It is not to string(.NET UTF16), so Jil, NetJSON and Json.NET contains additional UTF8.GetBytes/UTF8.GetString call. Definitely means does not exists encoding/decoding cost. Benchmark code is in sandbox/PerfBenchmark by BenchmarkDotNet.
