Hi i'm having problems with the function EVP_DecryptFinal_ex... i have
the next code:
#include stdio.h
#include string.h
#include libgen.h
#include wchar.h
#include sys/time.h
#include openssl/pem.h
#include openssl/sha.h
#include openssl/hmac.h
#include openssl/evp.h
#include openssl/bio.h
When i use to encrypt data, i have not problems.. when i
decrypt the result of this code, i have not problem...
when i decrypt with this program, i have
13015:error:06065064:digital envelope routines:
EVP_DecryptFinal_ex:bad decrypt:evp_enc.c:461:
The EVP_DecryptUpdate works ok, decrypt
buff = (char *)malloc(bptr-length);
memcpy(buff, bptr-data, bptr-length-1);
buff[bptr-length-1] = 0;
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 when

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++

After doing this I could encrypt / decrypt upto 7 KB only.
The code fails after 7 KB.
Please help.
thanks
