gmssl: Decrypt a file using the ZUC cipher.

gmssl

$ gmssl zuc -d -in ${filename-zuc}

try on your machine

This command is using the gmssl command line tool to decrypt a file using the ZUC encryption algorithm.

Here's a breakdown of each component of the command:

gmssl: This is the command to execute the gmssl tool. gmssl is an open-source cryptographic library that provides various algorithms and functionality for secure communication and data encryption.
zuc: This specifies the specific algorithm to be used, which is ZUC in this case. ZUC is a stream cipher algorithm used for encryption and decryption of data.
-d: This flag stands for "decrypt" and instructs gmssl to perform decryption instead of encryption.
-in ${filename-zuc}: This specifies the file to be decrypted. ${filename-zuc} represents the placeholder for the file name. You need to replace ${filename-zuc} with the actual name or path of the file you want to decrypt. The -in option is used to specify the input file for the operation.

So, when you run this command with the appropriate file name, gmssl will use the ZUC algorithm to decrypt the specified file.
