37 AES for 128, 192 and 256 bit keys in the following modes: CBC, CFB
38 with 128-bit shift, CFB with 1-bit shift, CFB with 8-bit shift,
39 CTR, ECB, and OFB.
40 EVP_aes_128_cbc_hmac_sha1(), EVP_aes_256_cbc_hmac_sha1()
42 Authenticated encryption with AES in CBC mode using SHA-1 as HMAC,
43 with keys of 128 and 256 bits length respectively. The
44 authentication tag is 160 bits long.
45 WARNING: this is not intended for usage outside of TLS and requires
47 calling of some undocumented ctrl functions. These ciphers do not
48 conform to the EVP AEAD interface.
49 EVP_aes_128_cbc_hmac_sha256(), EVP_aes_256_cbc_hmac_sha256()
51 Authenticated encryption with AES in CBC mode using SHA256 (SHA-2,
52 256-bits) as HMAC, with keys of 128 and 256 bits length
53 respectively. The authentication tag is 256 bits long.
54 WARNING: this is not intended for usage outside of TLS and requires
56 calling of some undocumented ctrl functions. These ciphers do not

62 AES for 128, 192 and 256 bit keys in CBC-MAC Mode (CCM), Galois
63 Counter Mode (GCM) and OCB Mode respectively. These ciphers require
64 additional control operations to function correctly, see the "AEAD

70 EVP_aes_192_wrap(), EVP_aes_256_wrap(), EVP_aes_256_wrap_pad()
71 AES key wrap with 128, 192 and 256 bit keys, as according to RFC
72 3394 section 2.2.1 ("wrap") and RFC 5649 section 4.1 ("wrap with
73 padding") respectively.
74 EVP_aes_128_xts(), EVP_aes_256_xts()
76 AES XTS mode (XTS-AES) is standardized in IEEE Std. 1619-2007 and
77 described in NIST SP 800-38E. The XTS (XEX-based tweaked-codebook
78 mode with ciphertext stealing) mode was designed by Prof. Phillip
79 Rogaway of University of California, Davis, intended for encrypting
80 data on a storage device.
81 XTS-AES provides confidentiality but not authentication of data. It
83 also requires a key of double-length for protection of a certain
84 key size. In particular, XTS-AES-128 (EVP_aes_128_xts) takes input
85 of a 256-bit key to achieve AES 128-bit security, and XTS-AES-256
86 (EVP_aes_256_xts) takes input of a 512-bit key to achieve AES
87 256-bit security.

91 implementation of the symmetric cipher. See EVP_CIPHER_meth_new(3) for
92 details of the EVP_CIPHER structure.
