iv(integrity verification) toolkits完整性验证工具链说明
#使用帮助
[root@5gc iv]# ./iv
Usage:
./iv generate_private_key private_key_name
./iv generate_public_key private_key_name public_key_name
./iv signature private_key_name source_cms_file source_file
./iv verify_signature public_key_name source_cms_file source_file
#生成私钥
[root@5gc iv]# ./iv generate_private_key pri.key
Generating RSA private key, 2048 bit long modulus (2 primes)
..............+++++
...................+++++
e is 65537 (0x010001)
en pri.key_pri.key ==> pri.key_pri.key.aes_en
注意:这时候私钥已经被自动加密存储了
#通过私钥生成公钥
[root@5gc iv]# ./iv generate_public_key pri.key pub.key
writing RSA key
#签名
#source.bin 是某个二进制的文件,安装包、升级包或者任何其他文件
#source.cms 是生成的签名文件
[root@5gc iv]# ./iv signature pri.key source.cms source.bin
#验证通过
[root@5gc iv]# ./iv verify_signature pub.key source.cms source.bin
Verified OK
#修改原始文件后,验证不通过
[root@5gc iv]# vi source.bin
[root@5gc iv]# ./iv verify_signature pub.key source.cms source.bin
Verification Failure
#针对修改后的source.bin再次签名验证通过
[root@5gc iv]# ./iv signature pri.key source.cms source.bin
[root@5gc iv]# ./iv verify_signature pub.key source.cms source.bin
Verified OK
#修改签名文件后,验证不通过
[root@5gc iv]# vi source.cms
[root@5gc iv]# ./iv verify_signature pub.key source.cms source.bin
Verification Failure
