hashcat:tldr:79a81

This command is using a tool called hashcat to perform offline password cracking. Here is a breakdown of the different parts:

• hashcat is the name of the tool/command used for password cracking.
• --hash-type ${hash_type_id} is an option that specifies the type of hash algorithm used for the password hash. ${hash_type_id} is a placeholder variable that should be replaced with the actual hash type ID.
• --attack-mode ${3} is an option that specifies the attack mode to be used. ${3} is a placeholder variable that should be replaced with the desired attack mode ID.
• ${hash_value} is the hash value of the password you want to crack. This should be replaced with the actual hash value obtained from the target system.
• "${?d?d?d?d}" is a placeholder for the password mask. This specifies the format/digits of the password to be cracked. In this example, it is set to a four-digit numeric password. Each ?d represents a digit placeholder.

To use this command, you need to replace ${hash_type_id} with the correct hash type ID, ${3} with the desired attack mode ID, and ${hash_value} with the actual hash value.
