Thanks for updated patch. Although EVP_CIPHER_CTX_cleanup() seems deprecated in OpenSSL >= 1.1.0 i.e.
# if OPENSSL_API_COMPAT < 0x10100000L
# define EVP_CIPHER_CTX_init(c) EVP_CIPHER_CTX_reset(c)
# define EVP_CIPHER_CTX_cleanup(c) EVP_CIPHER_CTX_reset(c)
# endif
I guess use of deprecated function is fine, until OpenSSL library support it.

I thought I tested that... But yes, that would not compile when linked
with 1.0.2 or older. Using EVP_CIPHER_CTX_cleanup() is safe instead as
that's available down to 0.9.8.
