## 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\_aria\_128\_cbc*.

## DESCRIPTION

The ARIA encryption algorithm for EVP.

- **EVP\_aria\_128\_cbc()**, **EVP\_aria\_192\_cbc()**, **EVP\_aria\_256\_cbc()**, **EVP\_aria\_128\_cfb()**, **EVP\_aria\_192\_cfb()**, **EVP\_aria\_256\_cfb()**, **EVP\_aria\_128\_cfb1()**, **EVP\_aria\_192\_cfb1()**, **EVP\_aria\_256\_cfb1()**, **EVP\_aria\_128\_cfb8()**, **EVP\_aria\_192\_cfb8()**, **EVP\_aria\_256\_cfb8()**, **EVP\_aria\_128\_cfb128()**, **EVP\_aria\_192\_cfb128()**, **EVP\_aria\_256\_cfb128()**, **EVP\_aria\_128\_ctr()**, **EVP\_aria\_192\_ctr()**, **EVP\_aria\_256\_ctr()**, **EVP\_aria\_128\_ecb()**, **EVP\_aria\_192\_ecb()**, **EVP\_aria\_256\_ecb()**, **EVP\_aria\_128\_ofb()**, **EVP\_aria\_192\_ofb()**, **EVP\_aria\_256\_ofb()**

  ARIA 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\_aria\_128\_ccm()**, **EVP\_aria\_192\_ccm()**, **EVP\_aria\_256\_ccm()**, **EVP\_aria\_128\_gcm()**, **EVP\_aria\_192\_gcm()**, **EVP\_aria\_256\_gcm()**,

  ARIA for 128, 192 and 256 bit keys in CBC-MAC Mode (CCM) and Galois Counter Mode (GCM). These ciphers require additional control operations to function correctly, see the "AEAD Interface" in **EVP\_EncryptInit**(3) section for details.

## 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.
