✨ NAME ✨

FBB::IBase64Stream — a std::istream that does base64 encoding and decoding, bestie 💖

This one lives in the 3bobcat section of the manual, so if you were hunting for it, hi, you found it 🫶

---

🌸 SYNOPSIS 🌸

#include <bobcat/ibase64stream>

Linking option: -lbobcat

---

🦋 DESCRIPTION 🦋

okay so picture this: you've got info chillin' on some separate std::istream, and you wanna base64 encode it or decode it. That's literally what FBB::IBase64Stream objects are for, no cap ✨

Here's the cute part: IBase64Stream is a class template, and it takes an FBB::CryptType template non-type parameter. So:

• objects of the class FBB::IBase64Stream<FBB::ENCRYPT> base64 encode the information they receive 🔥
• objects of the class FBB::IBase64Stream<FBB::DECRYPT> base64 decode the information they receive 💅

---

💜 NAMESPACE 💜

FBB

Every constructor, member, operator and manipulator mentioned in this man-page is defined in the namespace FBB. All of them. Every single one 👑

---

🌈 INHERITS FROM 🌈

• FBB::IBase64Buf (private)
• std::istream

---

🎀 CONSTRUCTORS 🎀

• IBase64Stream<CryptType>(std::istream &in, size_t bufSize = 1000) — this constructor initializes a std::istream and hooks it up with an FBB::IBase64Buf stream buffer. The IBase64Buf's constructor receives all the arguments that get passed to this constructor 🫶

So here's the vibe breakdown:

• IBase64Stream<ENCRYPT> objects perform base64 encoding;
• IBase64Stream<DECRYPT> objects perform base64 decoding;
• IBase64Stream<CryptType> objects obtain the bytes to encode or decode from std::istream &in;
• the internally used IFilterBuf is initialized with a buffer of size bufSize, using a lower bound of 100.

The constructor uses a configurable buffer size for reading. And listen, this part matters: characters that were read into the buffer but are not part of the actual base64 encoded data are unavailable after completing the base64 decrypting 😭 so if information beyond the base64 input block should remain available, then specify a buffer size of 1. Yeah. 1.

Copy and move constructors (and assignment operators) are not available. Not a thing. Don't try it 🙈

👑 INHERITED MEMBERS 👑

Since the class uses public derivation from std::istream, all members of this class can be used. go off, std::istream 💅

⭐ EXAMPLE ⭐

#include <iostream>

#include <bobcat/ibase64stream>

using namespace std;
using namespace FBB;

int main()
{
    IBase64Stream<ENCRYPT> in(cin);
}
