| Please note that the kernel crypto API contains the AEAD givcrypt API |
| (crypto_aead_giv\* and aead_givcrypt\* function calls in |
| include/crypto/aead.h). This API is obsolete and will be removed in the |
| future. To obtain the functionality of an AEAD cipher with internal IV |
| generation, use the IV generator as a regular cipher. For example, |
| rfc4106(gcm(aes)) is the AEAD cipher with external IV generation and |
| seqniv(rfc4106(gcm(aes))) implies that the kernel crypto API generates |
| the IV. Different IV generators are available. |
