 Limitations
 -----------
 
-* Hash only is not supported except SNOW 3G UIA2 and KASUMI F9.
 * Only supports the session-oriented API implementation (session-less APIs are not supported).
-* SNOW 3G (UEA2) and KASUMI (F8) supported only if cipher length, cipher offset fields are byte-aligned.
-* SNOW 3G (UIA2) and KASUMI (F9) supported only if hash length, hash offset fields are byte-aligned.
+* SNOW 3G (UEA2), KASUMI (F8) and ZUC (EEA3) supported only if cipher length and offset fields are byte-multiple.
+* SNOW 3G (UIA2), KASUMI (F9) and ZUC (EIA3) supported only if hash length and offset fields are byte-multiple.
 * No BSD support as BSD QAT kernel driver not available.
 * ZUC EEA3/EIA3 is not supported by dh895xcc devices
+* Maximum additional authenticated data (AAD) for GCM is 240 bytes long.
