Hi team, I am able to successfully encrypt custom device physical partition using dmsetup utility. I have used dm-crypt and dm-integrity for the same. I have one query related to IV generation of dm-crypt. Query: Whether Random number generator used to generate IV, generates same IV repeatedly or unique IV will be generated ? How the IV generation handled in dm-crypt ? The commands I used to create dm-integrity and dm-crypt is as below dmsetup create test-integrity --table '0 14240 integrity /dev/mmcblk0p5 0 32 J 1 internal_hash:hmac(sha256):30313233343536373839414243444546303132333435 36373839414243444546' dmsetup create test-integrity-crypt --table '0 14240 crypt aes-cbc- essiv:sha256 :32:user:test-key 0 /dev/mapper/test-integrity 0' Please give your valuable response for the above query.
