[PULL 16/17] crypto/nettle: Split QCryptoCipherNettle into subclasses |
Date: |
Thu, 10 Sep 2020 11:06:22 +0100 |
From: Richard Henderson <richard.henderson@linaro.org>
Use separate classes for each cipher entry point: des_rfb, des3,
aes128, aes192, aes256, cast128, serpent, and twofish.
Generate wrappers for XTS only for CONFIG_QEMU_PRIVATE_XTS.
This eliminates unreachable wrappers for DES_RFB, DES3 and
CAST128, which have blocksizes that do not allow XTS mode.
