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

=> More information.

• 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
