HEAP CORRUPTION DETECTED #3

Closed ted944 closed 2 years ago

ted944 commented 5 years ago

I've compiled the example and src using Visual Studio 2010 and linked to the openssl static library.

I'm getting this error while stepping through the example.cpp (I changed the files to cpp so they will compile with VS 2010) file. The error happened at line 196 (OPENSSL_free(Bytes);) in ff1.cpp.

Any idea what caused this?

0NG commented 5 years ago

I tested it with VS2017 and openSSL on Windows, and it works well except that I found a small bug in test.py:smile:. Could you provide more information, such as what version of openSSL you used? I think maybe the problem was caused by that openSSL.

Is there a C++ version i can use to build and check ?

Is there a C++ version i can use to build and check ?

I think the codes are compatible with C++. Just use any C++ compiler, such as g++. Actually, I used CL in this issue and it succeeded.

Hey, i am able to run it successfully, do you have the input combinations for text and numeric plaintext along with key,tweak and radix so i can check. Also does it support special characters as plaintext ? How do we address that

@kar12thik

do you have the input combinations for text and numeric plaintext along with key,tweak and radix so i can check

All the tests are in test.py. You can also find these from NIST document.

does it support special characters as plaintext

Yes if you know how ff1/ff3 works. Like example.c, you can choose an appropriate radix and map any character to a number
