编译与安装

Linux平台

$ mkdir build
$ cd build
$ cmake ..
$ make
$ make test
$ sudo make install

安装之后可以执行gmssl命令行工具检查是否成功

$ gmssl version

SM4加密解密

$ KEY=11223344556677881122334455667788
$ IV=11223344556677881122334455667788$ echo hello | gmssl sm4 -cbc -encrypt -key $KEY -iv $IV -out sm4.cbc
$ gmssl sm4 -cbc -decrypt -key $KEY -iv $IV -in sm4.cbc$ echo hello | gmssl sm4 -ctr -encrypt -key $KEY -iv $IV -out sm4.ctr
$ gmssl sm4 -ctr -decrypt -key $KEY -iv $IV -in sm4.ctr

SM3摘要

$ echo -n abc | gmssl sm3
$ gmssl sm2keygen -pass 1234 -out sm2.pem -pubout sm2pub.pem
$ echo -n abc | gmssl sm3 -pubkey sm2pub.pem -id 1234567812345678
$ echo -n abc | gmssl sm3hmac -key 11223344556677881122334455667788

SM2签名及验签

$ gmssl sm2keygen -pass 1234 -out sm2.pem -pubout sm2pub.pem$ echo hello | gmssl sm2sign -key sm2.pem -pass 1234 -out sm2.sig #-id 1234567812345678
$ echo hello | gmssl sm2verify -pubkey sm2pub.pem -sig sm2.sig -id 1234567812345678$ echo hello | gmssl sm2encrypt -pubkey sm2pub.pem -out sm2.der
$ gmssl sm2decrypt -key sm2.pem -pass 1234 -in sm2.der

---

SM2加密及解密

$ gmssl sm2keygen -pass 1234 -out sm2.pem -pubout sm2pub.pem$ echo hello | gmssl sm2encrypt -pubkey sm2pub.pem -out sm2.der
$ gmssl sm2decrypt -key sm2.pem -pass 1234 -in sm2.der

---

生成SM2根证书rootcakey.pem及CA证书cakey.pem

$ gmssl sm2keygen -pass 1234 -out rootcakey.pem
$ gmssl certgen -C CN -ST Beijing -L Haidian -O PKU -OU CS -CN ROOTCA -days 3650 -key rootcakey.pem -pass 1234 -out rootcacert.pem -key_usage keyCertSign -key_usage cRLSign
$ gmssl certparse -in rootcacert.pem$ gmssl sm2keygen -pass 1234 -out cakey.pem
$ gmssl reqgen -C CN -ST Beijing -L Haidian -O PKU -OU CS -CN "Sub CA" -days 3650 -key cakey.pem -pass 1234 -out careq.pem
$ gmssl reqsign -in careq.pem -days 365 -key_usage keyCertSign -path_len_constraint 0 -cacert rootcacert.pem -key rootcakey.pem -pass 1234 -out cacert.pem

---

使用CA证书签发签名证书和加密证书

$ gmssl sm2keygen -pass 1234 -out signkey.pem
$ gmssl reqgen -C CN -ST Beijing -L Haidian -O PKU -OU CS -CN localhost -days 365 -key signkey.pem -pass 1234 -out signreq.pem
$ gmssl reqsign -in signreq.pem -days 365 -key_usage digitalSignature -cacert cacert.pem -key cakey.pem -pass 1234 -out signcert.pem$ gmssl sm2keygen -pass 1234 -out enckey.pem
$ gmssl reqgen -C CN -ST Beijing -L Haidian -O PKU -OU CS -CN localhost -days 365 -key enckey.pem -pass 1234 -out encreq.pem
$ gmssl reqsign -in encreq.pem -days 365 -key_usage keyEncipherment -cacert cacert.pem -key cakey.pem -pass 1234 -out enccert.pem

将签名证书和ca证书合并为服务端证书certs.pem，并验证

$ cat signcert.pem > certs.pem
$ cat cacert.pem >> certs.pem
$ gmssl certverify -in certs.pem -cacert rootcacert.pem

查看证书内容：

$ gmssl certparse -in cacert.pem
