295is an 296.Vt uio 297structure. |
298.It Dv CRYPTO_F_REL 299Must return data in the same place. 300.It Dv CRYPTO_F_BATCH 301Batch operation if possible. 302.It Dv CRYPTO_F_CBIMM 303Do callback immediatelly instead of doing it from a dedicated kernel thread. 304.It Dv CRYPTO_F_DONE 305Operation completed. --- 46 unchanged lines hidden (view full) --- 352For encryption algorithms, this is where the initialization vector 353(IV) will be inserted when encrypting or where it can be found when 354decrypting (subject to 355.Va crd_flags ) . 356For MAC algorithms, this is where the result of the keyed hash will be 357inserted. 358.It Va crd_flags 359The following flags are defined: |
360.Bl -tag -width 3n |
361.It Dv CRD_F_ENCRYPT 362For encryption algorithms, this bit is set when encryption is required 363(when not set, decryption is performed). 364.It Dv CRD_F_IV_PRESENT 365For encryption algorithms, this bit is set when the IV already 366precedes the data, so the 367.Va crd_inject 368value will be ignored and no IV will be written in the buffer. --- 296 unchanged lines hidden --- |
