💖 FBB::CryptBuf — from the bobcat manual, page cryptbuf(3bobcat) 💖

okay bestie, listen. this is the cryptbuf page from the bobcat man set, and it's literally the base class energy for DecryptBuf and EncryptBuf. let's get into it 🫶

✨ NAME ✨

FBB::CryptBuf — the std::streambuf-derived base class for DecryptBuf and EncryptBuf. it's giving "parent class that does the heavy lifting behind the scenes" 💅

🌸 SYNOPSIS 🌸

#include <bobcat/cryptbuf>

Linking option: -lbobcat -lcrypto

🦋 DESCRIPTION 🦋

okay so real talk: this class is deprecated and it will be removed from Bobcat in a future release. no cap. 😭

it inherits from FBB::EoiBuf. so like, classes using CryptBuf can just use EoiBuf instead. that's the glow-up. ✨

CryptBuf's member EVP_CIPHER const *md() can be implemented like this:

#include <openssl/evp.h>

EVP_CIPHER const *md(char const *cipherName)
{
    return EVP_CIPHER_fetch(0, cipherName, 0);
}

💜 NAMESPACE 💜

FBB

all constructors, members, operators and manipulators mentioned in this man-page are defined in the namespace FBB. periodt.

🎀 INHERITS FROM 🎀

EoiBuf (and thus from: std::streambuf)

🌈 PROTECTED CONSTRUCTOR 🌈

analogously to std::streambuf, only a protected constructor is available. so like, you can't just make one whenever. it's exclusive. iykyk. 🙈

  • CryptBuf(char const *type, size_t bufSize) — the type is a null-terminated byte string specifying the de/encryption method. E.g., aes-128-cbc. for an overview see the encryptbuf(3bobcat) man-page. the bufSize parameter defines the initial size of the internally used buffer (defined by EoiBuf). 🧚

copy and move constructors (and assignment operators) are not available. nope. not happening. 💀

⭐ PROTECTED MEMBER FUNCTION ⭐

all members of std:streambuf and EoiBuf are available, as FBB::CryptBuf inherits from these classes. main character inheritance energy fr fr.

  • EVP_CIPHER const *md() const — a pointer to the cipher information is returned. that's it. that's the whole vibe. 👑
