svn commit: r1728963 - /apr/apr/trunk/crypto/apr_crypto_openssl.c
Author: rjung
Date: Sun Feb 7 14:16:13 2016
New Revision: 1728963
URL: http://svn.apache.org/viewvc?rev=1728963&view=rev
Log:
Add support for OpenSSL 1.1.0:
- choose OPENSSL_malloc_init() instead of
CRYPTO_malloc_init
- make cipherCtx a pointer. Type EVP_CIPHER_CTX
is now opaque.
- use EVP_CIPHER_CTX_new() in init() functions
if initialised flag is not set (and set flag)
- use EVP_CIPHER_CTX_free() in cleanup function
- Improve reuse cleanup
- call EVP_CIPHER_CTX_reset() resp.
EVP_CIPHER_CTX_cleanup() in finish functions
- call EVP_CIPHER_CTX_reset() resp.
EVP_CIPHER_CTX_cleanup() when Update fails
