Keepass中使用了一个Argon2的算法来存储用户主密码，这个算法被认为是下一代的较为安全的密码散列算法。 我们来看看 Argon2算法：
hfli@CNhfli ~/Documents/phc-winner-argon2 (master*) $ echo -n "password" | ./argon2 somehelloworld -t 2 -m 16 -p 4 -l 24 Type: Argon2i Iterations: 2 Memory: 65536 KiB Parallelism: 4 Hash: 2748e90a5a301dbcf46067a8784d3e73c7acc8939b4ee02d Encoded: $argon2i$v=19$m=65536,t=2,p=4$c29tZWhlbGxvd29ybGQ$J0jpClowHbz0YGeoeE0+c8esyJObTuAt 0.126 seconds Verification ok
这个算法又分为两个版本,Argon2i和Argon2d:
> Argon2d provides the highest resistance against GPU cracking attacks. Argon2i is designed to resist side-channel attacks.
Keepass中选择的是Argon2d
> Only the Argon2d variant of Argon2 is supported (a strong defense against GPU/ASIC cracking attacks is the most important goal, and Argon2d here is better than Argon2i; side-channel timing attacks are basically irrelevant, because KeePass is a local application, not a remote server)
在安卓上编译可以参考如下步骤:
Application.mk
APP_BUILD_SCRIPT := Android.mk APP_STL := gnustl_shared APP_ABI := armeabi-v7a
Android.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libargon2
LOCAL_CPPFLAGS += -fexceptions
LOCAL_C_INCLUDES := \
$(LOCAL_PATH) \
$(LOCAL_PATH)/include \
LOCAL_SRC_FILES := \
src/argon2.c \
src/core.c \
src/blake2/blake2b.c \
src/encoding.c \
src/ref.c \
src/thread.c \
include $(BUILD_SHARED_LIBRARY)
