Umm, you don't copy the last byte of data. You don't allocate enough space to
hold the data and a terminator. This is probably your main error. How will
'buff' hold a C-style string wh

Hi, I'm trying to write simple AES encryption/decryption routines. I'm
having trouble with the decryption routine, specifically, I get this error:
27013:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad
decrypt:evp_enc.c:461:
I've included my code below; I compile it with:
g++ -o
After doing this I could encrypt / decrypt upto 7 KB only.
The code fails after 7 KB.
Please help.
thanks

I am still struggling with this issue.
I did not get much help from the list, so I am reposting again.
