NAME

       EVP_CIPHER-AES - The AES EVP_CIPHER implementations


DESCRIPTION

       Support for AES symmetric encryption using the EVP_CIPHER API.

   Algorithm Names
       The following algorithms are available in the FIPS provider as well as
       the default provider:

       "AES-128-CBC", "AES-192-CBC" and  "AES-256-CBC"
       "AES-128-CBC-CTS", "AES-192-CBC-CTS" and "AES-256-CBC-CTS"
       "AES-128-CFB", "AES-192-CFB", "AES-256-CFB", "AES-128-CFB1",
       "AES-192-CFB1", "AES-256-CFB1", "AES-128-CFB8", "AES-192-CFB8" and
       "AES-256-CFB8"
       "AES-128-CTR", "AES-192-CTR" and "AES-256-CTR"
       "AES-128-ECB", "AES-192-ECB" and "AES-256-ECB"
       "AES-192-OFB", "AES-128-OFB" and "AES-256-OFB"
       "AES-128-XTS" and "AES-256-XTS"
       "AES-128-CCM", "AES-192-CCM" and "AES-256-CCM"
       "AES-128-GCM", "AES-192-GCM" and "AES-256-GCM"
       "AES-128-WRAP", "AES-192-WRAP", "AES-256-WRAP", "AES-128-WRAP-PAD",
       "AES-192-WRAP-PAD", "AES-256-WRAP-PAD", "AES-128-WRAP-INV",
       "AES-192-WRAP-INV", "AES-256-WRAP-INV", "AES-128-WRAP-PAD-INV",
       "AES-192-WRAP-PAD-INV" and "AES-256-WRAP-PAD-INV"
       "AES-128-CBC-HMAC-SHA1", "AES-256-CBC-HMAC-SHA1",
       "AES-128-CBC-HMAC-SHA256" and "AES-256-CBC-HMAC-SHA256"

       The following algorithms are available in the default provider, but not
       the FIPS provider:

       "AES-128-OCB", "AES-192-OCB" and "AES-256-OCB"
       "AES-128-SIV", "AES-192-SIV" and "AES-256-SIV"

   Parameters
       This implementation supports the parameters described in "PARAMETERS"
       in EVP_EncryptInit(3).


NOTES

       The AES-SIV and AES-WRAP mode implementations do not support streaming.
       That means to obtain correct results there can be only one
       EVP_EncryptUpdate(3) or EVP_DecryptUpdate(3) call after the
       initialization of the context.

       The AES-XTS implementations allow streaming to be performed, but each
       EVP_EncryptUpdate(3) or EVP_DecryptUpdate(3) call requires each input
       to be a multiple of the blocksize. Only the final EVP_EncryptUpdate()
       or EVP_DecryptUpdate() call can optionally have an input that is not a
       multiple of the blocksize but is larger than one block. In that case
       ciphertext stealing (CTS) is used to fill the block.
