I mailed the OpenSLL User list to find a place to download
new binaries. Their normal download page is source only.

The reason I'd like an upgrade is that EVP_CIPHER_CTX_new were
added in 0.9.8d. Before that release you were supposed to


to allocate a new cipher context (or use sizeof(EVP_CIPHER_CTX)).

The function EVP_CIPHER_CTX_new allocates and initializes, so
it takes care of the problem.

So far I have just allocated a large array, that I guess
is big enough on all platforms.
