Password searching method and system in multi-node parallel-processing environment

摘要

Provided are a method and a system for decrypting a password in multi-node parallel-processing environment including a master node and a plurality of work nodes. The master node receives information on encrypted file selection from a user. The master node generates password candidate information generation information and transmits the password candidate to the plurality of work nodes together with a password decryption command. The password candidate generation information allows the plurality of work nodes to have different password candidate ranges using password decryption information comprising a maximum password length, a minimum password length, and a string set constituting the password. The work node decrypts the password using the password candidate generation information. The work node transmits the password decryption result to the master node.
