gmssl:tldr:bfe96
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 thegmssl
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.
