/**
+ * DOC: Authenticated Encryption With Associated Data (AEAD) Cipher API
+ *
+ * The AEAD cipher API is used with the ciphers of type CRYPTO_ALG_TYPE_AEAD
+ * (listed as type "aead" in /proc/crypto)
+ *
+ * The most prominent examples for this type of encryption is GCM and CCM.
+ * However, the kernel supports other types of AEAD ciphers which are defined
+ * with the following cipher string:
+ *
+ * authenc(keyed message digest, block cipher)
+ *
+ * For example: authenc(hmac(sha256), cbc(aes))
+ *
+ * The example code provided for the asynchronous block cipher operation
+ * applies here as well. Naturally all *ablkcipher* symbols must be exchanged
+ * the *aead* pendants discussed in the following. In addition, for the AEAD
+ * operation, the aead_request_set_assoc function must be used to set the
+ * pointer to the associated data memory location before performing the
+ * encryption or decryption operation. In case of an encryption, the associated
+ * data memory is filled during the encryption operation. For decryption, the
+ * associated data memory must contain data that is used to verify the integrity
+ * of the decrypted data. Another deviation from the asynchronous block cipher
+ * operation is that the caller should explicitly check for -EBADMSG of the
+ * crypto_aead_decrypt. That error indicates an authentication error, i.e.
+ * a breach in the integrity of the message. In essence, that -EBADMSG error
+ * code is the key bonus an AEAD cipher has over "standard" block chaining
+ * modes.

- * DOC: Authenticated Encryption With Associated Data (AEAD) Cipher API
- *
- * The AEAD cipher API is used with the ciphers of type CRYPTO_ALG_TYPE_AEAD
- * (listed as type "aead" in /proc/crypto)
- *
- * The most prominent examples for this type of encryption is GCM and CCM.
- * However, the kernel supports other types of AEAD ciphers which are defined
- * with the following cipher string:
- *
- * authenc(keyed message digest, block cipher)
- *
- * For example: authenc(hmac(sha256), cbc(aes))
- *
- * The example code provided for the asynchronous block cipher operation
- * applies here as well. Naturally all *ablkcipher* symbols must be exchanged
- * the *aead* pendants discussed in the following. In addtion, for the AEAD
- * operation, the aead_request_set_assoc function must be used to set the
- * pointer to the associated data memory location before performing the
- * encryption or decryption operation. In case of an encryption, the associated
- * data memory is filled during the encryption operation. For decryption, the
- * associated data memory must contain data that is used to verify the integrity
- * of the decrypted data. Another deviation from the asynchronous block cipher
- * operation is that the caller should explicitly check for -EBADMSG of the
- * crypto_aead_decrypt. That error indicates an authentication error, i.e.
- * a breach in the integrity of the message. In essence, that -EBADMSG error
- * code is the key bonus an AEAD cipher has over "standard" block chaining
- * modes.
