++
++ #include <openssl/evp.h>
++
++ int EVP_AEAD_CTX_init(EVP_AEAD_CTX *ctx, const EVP_AEAD *aead,
++ const unsigned char *key, size_t key_len,

++ ssize_t EVP_AEAD_CTX_open(const EVP_AEAD_CTX *ctx,

++ const unsigned char *nonce, size_t nonce_len,
++ const unsigned char *in, size_t in_len,
++ const unsigned char *ad, size_t ad_len);
++
++=head1 DESCRIPTION
++
++The EVP_AEAD_CTX_init() function initialises an B<EVP_AEAD_CTX> structure and
++performs any precomputation needed to use B<aead> with B<key>. The length of
++the key, B<key_len>, is given in bytes.
++
++The B<tag_len> argument contains the length of the tags, in bytes, and allows
++for the processing of truncated authenticators. A zero value indicates that the
++default tag length should be used and this is defined as
++C<EVP_AEAD_DEFAULT_TAG_LENGTH> in order to make the code clear. Using truncated
++tags increases an attacker's chance of creating a valid forgery. Be aware that
++the attacker's chance may increase more than exponentially as would naively be
++expected.
++
++When no longer needed, the initialised B<EVP_AEAD_CTX> structure must be passed
++to EVP_AEAD_CTX_cleanup(), which will deallocate any memory used.
++
++With an B<EVP_AEAD_CTX> in hand, one can seal and open messages. These
++operations are intended to meet the standard notions of privacy and
++authenticity for authenticated encryption. For formal definitions see I<Bellare
++and Namprempre>, "Authenticated encryption: relations among notions and
++analysis of the generic composition paradigm," Lecture Notes in Computer
++Science B<1976> (2000), 531–545,
++L<http://www-cse.ucsd.edu/~mihir/papers/oem.html>.
++
++When sealing messages, a nonce must be given. The length of the nonce is fixed
++by the AEAD in use and is returned by EVP_AEAD_nonce_length(). I<The nonce must
++be unique for all messages with the same key>. This is critically important -
++nonce reuse may completely undermine the security of the AEAD. Nonces may be
++predictable and public, so long as they are unique. Uniqueness may be achieved
++with a simple counter or, if long enough, may be generated randomly. The nonce
++must be passed into the "open" operation by the receiver so must either be
++implicit (e.g. a counter), or must be transmitted along with the sealed message.
++
++The "seal" and "open" operations are atomic - an entire message must be
++encrypted or decrypted in a single call. Large messages may have to be split up
++in order to accomodate this. When doing so, be mindful of the need not to
++repeat nonces and the possibility that an attacker could duplicate, reorder or
++drop message chunks. For example, using a single key for a given (large)
++message and sealing chunks with nonces counting from zero would be secure as
++long as the number of chunks was securely transmitted. (Otherwise an attacker
++could truncate the message by dropping chunks from the end.)
++
++The number of chunks could be transmitted by prefixing it to the plaintext, for
++example. This also assumes that no other message would ever use the same key
++otherwise the rule that nonces must be unique for a given key would be
++violated.
++
++The "seal" and "open" operations also permit additional data to be
++authenticated via the B<ad> parameter. This data is not included in the
++ciphertext and must be identical for both the "seal" and "open" call. This
++permits implicit context to be authenticated but may be C<NULL> if not needed.
++
++The "seal" and "open" operations may work inplace if the B<out> and B<in>
++arguments are equal. They may also be used to shift the data left inside the
++same buffer if B<out> is less than B<in>. However, B<out> may not point inside
++the input data otherwise the input may be overwritten before it has been read.
++This case will cause an error.
++
++=head1 RETURN VALUES
++
++The "seal" and "open" operations return an C<ssize_t> with value -1 on error,
++otherwise they return the number of output bytes written. An error will be
++returned if the input length is large enough that the output size exceeds the
++range of a C<ssize_t>.
++

++
++These functions were first added to OpenSSL 1.0.2.

+Subject: [PATCH 52/52] Optional NEON support on ARM.
+
+This patch causes ARM to build both the NEON and generic versions of
+ChaCha20 and Poly1305. The NEON code can be enabled at run-time by
+calling CRYPTO_set_NEON_capable(1).

+
+The previous version of the function made adding AEAD changes very
+difficult. This change should be a semantic no-op - it should be purely
