+> GmSSL is a crypto toolkit supporting SM1, SM2, SM3, SM4, SM9, and ZUC/ZUC256.

+- Generate an SM3 hash for a file:
+
+`gmssl sm3 {{path/to/file}}`
+
+- Encrypt a file using the SM4 cipher:
+
+`gmssl sms4 -e -in {{path/to/file}} -out {{path/to/file.sms4}}`
+
+- Decrypt a file using the SM4 cipher:
+
+`gmssl sms4 -d -in {{path/to/file.sms4}}`
+
+- Generate an SM2 private key:
+
+`gmssl sm2 -genkey -out {{path/to/file.pem}}`
+
+- Generate an SM2 public key from an existing private key:
+
+`gmssl sm2 -pubout -in {{path/to/file.pem}} -out {{path/to/file.pem.pub}}`
+
+- Encrypt a file using the ZUC cipher:
+
+`gmssl zuc -e -in {{path/to/file}} -out {{path/to/file.zuc}}`
+
+- Decrypt a file using the ZUC cipher:
+
+`gmssl zuc -d -in {{path/to/file.zuc}}`
+
+- Print version:
+
+`gmssl version`
