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_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_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_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.
           The XTS implementation in OpenSSL does not support streaming. That
           is there must only be one EVP_EncryptUpdate(3) call per
           EVP_EncryptInit_ex(3) call (and similarly with the "Decrypt"
           functions).
           The iv parameter to EVP_EncryptInit_ex(3) or EVP_DecryptInit_ex(3)
           is the XTS "tweak" value.
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.
