Signed-off-by: Gilad Ben-Yossef --- crypto/tcrypt.c | 84 +++++----- 1 file changed, 25 insertions(+), 59 deletions(-) -- 2.1.4 Aug 07, 2019 · Instead of instantiating a separate cipher to perform the encryption needed to produce the IV, reuse the skcipher used for the block data and invoke it one additional time for each block to encrypt a zero vector and use the output as the IV. Invoking a possibly async. crypto op and waiting for completion while correctly handling backlog processing is a common task in the crypto API implementation and outside users of it.
