gmssl: Generate an SM2 private key.

gmssl

$ gmssl sm2 -genkey -out ${filename-pem}

The command gmssl sm2 -genkey -out ${filename-pem} is used to generate a SM2 key pair using the gmssl command line tool.

Here's a breakdown of the command:

gmssl: This is the name of the command-line tool used for cryptographic operations provided by the GmSSL library. GmSSL is an open-source cryptography library that supports various cryptographic algorithms.
sm2: This option specifies that we want to generate an SM2 key pair. SM2 is a digital signature algorithm based on elliptic curve cryptography (ECC) and is widely used in China.
-genkey: This flag instructs the gmssl tool to generate a new SM2 key pair.
-out ${filename-pem}: This option specifies the output file where the generated key pair will be saved. The ${filename-pem} is a placeholder that should be replaced with the desired name for the output file, which should have a .pem extension. PEM is a widely-used format for storing cryptographic objects like keys and certificates.

Overall, this command generates a new SM2 key pair and saves it in a PEM file specified by the ${filename-pem} placeholder.
