Hi, As I obviously needed to improve my test program, I am now encrypting and decrypting files trying all ciphers in all their available modes. ( ChaCha20, AES-128, AES-192, AES-256, Blowfish, Cast5, Camellia-128, Camellia-192, Camellia-256, IDEA, Seed, 3 Keys Triple-DES, 2 Keys Triple-DES ) ( Poly1305, OCB, GCM, OFB, CFB, CFB1, CFB8, CTR, CBC )
You are certainly already informed (as I believe it may be caused by the same problem that David diagnosed) but I felt preferable to report that even with an output buffer larger than the expected data size, I always got a heap corrupted, but *ONLY* when I use the CBC mode. FWIW, here is the call stack : [External Code] Test.exe!CRYPTO_free(void * str, const char * file, int line) Line 179 C Test.exe!buffer_free(bio_st * a) Line 76 C Test.exe!BIO_free(bio_st * a) Line 72 C Test.exe!OCrypto::IO::Free() Line 1204 C++ Test.exe!WinFile::Close() Line 388 C++ Test.exe!WinFile::~WinFile() Line 456 C++ Test.exe!LoadData(const char * sFullFileName) Line 186 C++ Test.exe!main(int argc, char * * argv) Line 154 C++ [External Code] HEAP CORRUPTION DETECTED All ciphers look to work good in all other modes than CBC (still using a buffer greater than needed).
