SYNOPSIS
	#include <openssl/evp.h>

	const EVP_CIPHER *EVP_ciphername(void)

       EVP_ciphername is used a	placeholder for	any of the described cipher
       functions, such as EVP_aes_128_cbc.

DESCRIPTION
       The AES encryption algorithm for	EVP.

       EVP_aes_128_cbc(), EVP_aes_192_cbc(), EVP_aes_256_cbc(),
       EVP_aes_128_cfb(), EVP_aes_192_cfb(), EVP_aes_256_cfb(),
       EVP_aes_128_cfb1(), EVP_aes_192_cfb1(), EVP_aes_256_cfb1(),
       EVP_aes_128_cfb8(), EVP_aes_192_cfb8(), EVP_aes_256_cfb8(),
       EVP_aes_128_cfb128(), EVP_aes_192_cfb128(), EVP_aes_256_cfb128(),
       EVP_aes_128_ctr(), EVP_aes_192_ctr(), EVP_aes_256_ctr(),
       EVP_aes_128_ecb(), EVP_aes_192_ecb(), EVP_aes_256_ecb(),
       EVP_aes_128_ofb(), EVP_aes_192_ofb(), EVP_aes_256_ofb()
	   AES for 128,	192 and	256 bit	keys in	the following modes: CBC, CFB
	   with	128-bit	shift, CFB with	1-bit shift, CFB with 8-bit shift,
	   CTR,	ECB, and OFB.

       EVP_aes_128_cbc_hmac_sha1(), EVP_aes_256_cbc_hmac_sha1()
	   Authenticated encryption with AES in	CBC mode using SHA-1 as	HMAC,
	   with	keys of	128 and	256 bits length	respectively. The
	   authentication tag is 160 bits long.

	   WARNING: this is not	intended for usage outside of TLS and requires
	   calling of some undocumented	ctrl functions.	These ciphers do not
	   conform to the EVP AEAD interface.

       EVP_aes_128_cbc_hmac_sha256(), EVP_aes_256_cbc_hmac_sha256()
	   Authenticated encryption with AES in	CBC mode using SHA256 (SHA-2,
	   256-bits) as	HMAC, with keys	of 128 and 256 bits length
	   respectively. The authentication tag	is 256 bits long.

	   WARNING: this is not	intended for usage outside of TLS and requires
	   calling of some undocumented	ctrl functions.	These ciphers do not
	   conform to the EVP AEAD interface.

       EVP_aes_128_ccm(), EVP_aes_192_ccm(), EVP_aes_256_ccm(),
       EVP_aes_128_gcm(), EVP_aes_192_gcm(), EVP_aes_256_gcm(),
       EVP_aes_128_ocb(), EVP_aes_192_ocb(), EVP_aes_256_ocb()
	   AES for 128,	192 and	256 bit	keys in	CBC-MAC	Mode (CCM), Galois
	   Counter Mode	(GCM) and OCB Mode respectively. These ciphers require
	   additional control operations to function correctly,	see the	"AEAD
	   Interface" in EVP_EncryptInit(3) section for	details.

       EVP_aes_128_wrap(), EVP_aes_192_wrap(), EVP_aes_256_wrap(),
       EVP_aes_128_wrap_pad(), EVP_aes_128_wrap(), EVP_aes_192_wrap(),
       EVP_aes_256_wrap(), EVP_aes_192_wrap_pad(), EVP_aes_128_wrap(),
       EVP_aes_192_wrap(), EVP_aes_256_wrap(), EVP_aes_256_wrap_pad()
	   AES key wrap	with 128, 192 and 256 bit keys,	as according to	RFC
	   3394	section	2.2.1 ("wrap") and RFC 5649 section 4.1	("wrap with
	   padding") respectively.

       EVP_aes_128_xts(), EVP_aes_256_xts()
	   AES XTS mode	(XTS-AES) is standardized in IEEE Std. 1619-2007 and
	   described in	NIST SP	800-38E. The XTS (XEX-based tweaked-codebook
	   mode	with ciphertext	stealing) mode was designed by Prof. Phillip
	   Rogaway of University of California,	Davis, intended	for encrypting
	   data	on a storage device.

	   XTS-AES provides confidentiality but	not authentication of data. It
	   also	requires a key of double-length	for protection of a certain
	   key size.  In particular, XTS-AES-128 (EVP_aes_128_xts) takes input
	   of a	256-bit	key to achieve AES 128-bit security, and XTS-AES-256
	   (EVP_aes_256_xts) takes input of a 512-bit key to achieve AES
	   256-bit security.

RETURN VALUES
       These functions return an EVP_CIPHER structure that contains the
       implementation of the symmetric cipher. See EVP_CIPHER_meth_new(3) for
       details of the EVP_CIPHER structure.
