From a7d85e06ed8033f263451f3aef4159024e7dae5f Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Thu, 1 Mar 2018 14:36:17 -0800 Subject: crypto: cfb - add support for Cipher FeedBack mode TPM security routines require encryption and decryption with AES in CFB mode, so add it to the Linux Crypto schemes. CFB is basically a one time pad where the pad is generated initially from the encrypted IV and then subsequently from the encrypted previous block of ciphertext. The pad is XOR'd into the plain text to get the final ciphertext. https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#CFB Signed-off-by: James Bottomley Signed-off-by: Herbert Xu --- crypto/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'crypto/Makefile') diff --git a/crypto/Makefile b/crypto/Makefile index 04517b29d839..39ad2fd4a128 100644 --- a/crypto/Makefile +++ b/crypto/Makefile @@ -78,6 +78,7 @@ obj-$(CONFIG_CRYPTO_TGR192) += tgr192.o obj-$(CONFIG_CRYPTO_GF128MUL) += gf128mul.o obj-$(CONFIG_CRYPTO_ECB) += ecb.o obj-$(CONFIG_CRYPTO_CBC) += cbc.o +obj-$(CONFIG_CRYPTO_CFB) += cfb.o obj-$(CONFIG_CRYPTO_PCBC) += pcbc.o obj-$(CONFIG_CRYPTO_CTS) += cts.o obj-$(CONFIG_CRYPTO_LRW) += lrw.o -- cgit
