gmssl: Encrypt a file using the SM4 cipher.
$ gmssl sms4 -e -in ${filename} -out ${filename-sms4}
try on your machine
This command is using the gmssl utility to encrypt a file using the SMS4 algorithm. Here is a breakdown of each part of the command:
gmssl
: This is the command to invoke the gmssl utility, which is used for cryptographic operations.sms4
: This is the specific algorithm being used for encryption, in this case, the SMS4 algorithm.-e
: This flag is used to specify that we want to perform encryption.-in ${filename}
: This specifies the input file to be encrypted.${filename}
is a placeholder for the actual filename, which should be replaced with the desired input file.-out ${filename-sms4}
: This specifies the output file, where the encrypted data will be saved.${filename-sms4}
is a placeholder for the output filename, which will be the same as the input filename with "-sms4" appended to it.
So, when you run this command with a specific filename, it will encrypt the content of that file using the SMS4 algorithm and save the encrypted data in a new file with the original filename followed by "-sms4".

never run a command you are not sure if it is safe.
