gmssl

GmSSL is a crypto toolkit supporting SM1, SM2, SM3, SM4, SM9, and ZUC/ZUC256. More information: http://gmssl.org/english.html.

• 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
