android 调用openssl库

一、openssl安装编译

下载openssl-1.1.1w.tar.gz和android-ndk-r21e-linux-x86_64.zip
解压android-ndk-r21e-linux-x86_64.zip到/opt/pj_ssl目录下，然后配置环境

vim ~/.bashrc
增加如下内容

export NDK_HOME=/opt/pj_ssl/android-ndk-r21e
export ANDROID_NDK_HOME=/opt/pj_ssl/android-ndk-r21e
export PATH=$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/bin:$ANDROID_NDK_HOME/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin:$PATH

刷新环境变量 source ~/.bashrc

编译环境

编译32位 ./Configure android-arm -D__ANDROID_API__=21 --prefix=/opt/pj_ssl/openssl-1.1.1w/obj
编译64位 ./Configure android-arm64 -D__ANDROID_API__=21 --prefix=/opt/pj_ssl/openssl-1.1.1w/obj
make
make install

将32位的libssl.a和libcrypto.a拷贝到armeabi-v7a
将64位的libssl.a和libcrypto.a拷贝到arm64-v8a

二、使用openssl库

1.在 Android.mk引用库

OPENSSL_PATH := $(ROOT_PATH)/opensslifeq ($(TARGET_ARCH_ABI),armeabi-v7a)
LOCAL_CFLAGS += -DPJ_M_ARMV7
OPENSSL_INC := $(OPENSSL_PATH)/armeabi-v7a/include
OPENSSL_SSL := $(OPENSSL_PATH)/armeabi-v7a/lib/libssl.a
OPENSSL_CRYPTO := $(OPENSSL_PATH)/armeabi-v7a/lib/libcrypto.aelse ifeq ($(TARGET_ARCH_ABI),arm64-v8a)
LOCAL_CFLAGS += -DPJ_M_ARMV8 -D_ARM_
OPENSSL_INC := $(OPENSSL_PATH)/arm64-v8a/include
OPENSSL_SSL := $(OPENSSL_PATH)/arm64-v8a/lib/libssl.a
OPENSSL_CRYPTO := $(OPENSSL_PATH)/arm64-v8a/lib/libcrypto.aLOCAL_LDFLAGS += \$(OPENSSL_SSL) \$(OPENSSL_CRYPTO)
