You've misunderstood how EVP_DecryptFinal should be used. You have
basically done the following:
EVP_DecryptInit(...)
loop
{
EVP_DecryptUpdate(...)
EVP_DecryptFinal(...)
}
when the correct way is the following:
EVP_DecryptInit(...)
loop
{
EVP_DecryptUpdate(...)
}
EVP_DecryptFinal(...)
Did that make sense to you?
Cheers,
Richard
