crossfire

distributed brute force infrastructure

takes the difficulty out of creating custom brute force jobs

status

base

• 🚧 input space manipulation functions
  • ✅ data types: using data/integer-set, pattern (vector of integer-set)
  • ✅ basic manipulation functions
  • ✅ representation of input space as a flat integer
• 🚧 #lang for configuration/definitions
  • (input) mode
    • stdio: user program gets input by stdio, integers separated by space, one per line
    • callback: input generator compiled into user program, user main calls crossfire_main with callback function that returns true or false
    • other modes??
  • SMP: performed by crossfire or performed by the user code
    • “performed by user code” can also mean GPU, for example
• 🚧 codegen for input generator (in C)
  • ✅ stdio mode
  • 🚧 callback mode
  • success reporting mechanism
  • low priority: configurable “character” type -- currently a “character” is a uint64_t

server: distribute jobs to workers

• ✅ base definitions of input classes and how to divide them
• ✅ dynamic slicing and scheduling based on agents’ reported work rate
• low priority: randomized input space distribution
• low priority: store common configuration templates for clients
• low priority: track upload/download progress
• streaming interface for file transfers
• ✅ accept submitted projects (with client-compiled input generator) and distribute to agents
  • ✅ low priority: support for multiple architectures
• ✅ agent authentication
• ✅ client authentication

agent: accept and run jobs

• ✅ securely connect to server
• retrieve assigned tasks
• report number of cores available (configurable limit)
• report work rate
• report successes
• low priority: defer to external brute force program (eg, hashcat on GPU)
• low priority: support finding all matching inputs for a project, rather than just the first one

client: submit jobs and view progress

• ✅securely connect to server
• command line interface
  • crossfire new: create new crossfire project
  • crossfire test: test project locally, replicates configuration of server with single local agent to debug issues
  • low priority: crossfire node-test: submit a mini-task to a node that has the necessary resources to debug issues
  • crossfire submit: submit task to server
  • crossfire cancel: cancels submitted task
  • crossfire status: check status of task (or network as a whole)
• low priority: gui interface (racket/gui & framework time)
