Editing the response

I've tried adding something like this in myEncrypt function:

char entitlements[] = R"(some
very
long
text)"
char* text = ((char*)*(DWORD*)a2);
char* new_text = nullptr;
new_text = (char*) malloc(strlen(entitlements) + 1);
strcpy(new_text, entitlements);
*(DWORD*)a2 = (DWORD)new_text;
free(text);

and it works fine - except for when my text is longer than the one I want to replace, then it crashes the game.

And I don't get something. At first IDA shows the encrypt function declaration as

class std::basic_string<char, struct std::char_traits<char>, class std::allocator<char>> __thiscall Origin::Services::Crypto::SimpleEncryption::encrypt(class std::basic_string<char, struct std::char_traits<char>, class std::allocator<char>> const &)

so I guess in short:

class std::string __thiscall Origin::Services::Crypto::SimpleEncryption::encrypt(class std::string const &)

but later, after autoanalysis it's

int __stdcall Origin::Services::Crypto::SimpleEncryption::encrypt(int, void *Src)

Do you have any tips on how to properly edit the response?

Is it something wrong with my system or Origin added some protections? When replacing the DLL, Origin doesn't start. Origin.exe appears for a second in taskmgr with like 20K memory and shortly after it disappears. Tried with both your libraries and self-compiled + winhttp from my system
