title: decrypt *.bin file in C using openssl
body: <p>i've got a question for my study stuff: I have to decrypt a file(src-cipher.bin) using C. I have a corrupt key corrupt-src-key.bin (an initial vector is at the end of the file - dont know if i should this vector- maybe dont have to). final decrypted file should be a *.pdf one and it was encrypted with Camellia-192-OFB (openssl EVP_camellia_192_ofb() ). Byte number 23(start counting from 0) was set to 0. Now i have to write a small C app which decrypts this file. At least ive got 2 more files(src-cipher.bin and dest-key.bin)). Thanks very much for help. If someone is interested, i can send the files. Thx </p>
