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
