Hi, All:
When i use the cryptsetup command to set the aes-xts-plain
encryption, the system will entry the crypt() routine which defined in
the xts.c file. I find the routine will call two important routines:
tw and fn. I think the fn will point to the aes_encrypt/decrypt
routine. But i want to know which routine the tw will point to for
aes-xts-plain encryption? and where i can find its source code? I put
the segment where the tw routine will be called in the bellow.
wsrc = w->src.virt.addr;
wdst = w->dst.virt.addr;
/* calculate first value of T */
tw(crypto_cipher_tfm(ctx->tweak), w->iv, w->iv);
goto first;
for (;;) {
do {
Thanks all!
Best Regards
