hashcat v7.1.0 - atom - 08-16-2025

Welcome to hashcat v7.1.0!

Download binaries and source code from hashcat or from GitHub

This is a minor release, but an important one. It comes just two weeks after the major v7.0.0 update, as part of our effort to keep release cycles shorter than in the past.

Although two weeks may seem quick, this version includes several important bug fixes along with notable new features and hash modes, which makes a v7.1.0 release fully justified.

If you have 5 minutes, here's the full writeup: Full Release Notes and detailed writeup

New Algorithms:
  • AS/400 DES
  • AS/400 SSHA1
  • Blockchain, My Wallet, Legacy Wallets
  • Cisco-ISE Hashed Password (SHA256)
  • LUKS2 (Argon2i KDF type)
  • KeePass (KDBX v4)
  • SAP CODVN H (PWDSALTEDHASH) isSHA512
  • sm3crypt $sm3$, SM3 (Unix)
  • BLAKE2b-256
  • BLAKE2b-256($pass.$salt)
  • BLAKE2b-256($salt.$pass)
  • MD6 (256)
  • sha224($pass.$salt)
  • sha224($salt.$pass)
  • sha224(sha1($pass))
  • sha224(sha224($pass))

New Features
  • Attack-Modes: Use 64-bit counters for amplifier keyspace
  • Host Memory: Update method to query free host memory
  • Add initial support for running hashcat inside Docker
  • Device Memory: Warn instead of waiting on high GPU memory usage
  • ... a lot more
  • See full writeup for details
These new features are particularly relevant if you have encountered the following types of error messages, as they address them efficiently:
  • Integer overflow detected in ...
  • Not enough allocatable device memory or free host memory ...
Here is a preview of running hashcat inside a Docker container:

This release was made possible thanks to the work of the hashcat community.

We appreciate the time, skill, and testing effort that went into it and especially from those submitting fixes, reporting bugs, and helping improve portability.

Welcome to hashcat 7.1.1 release!

This hotfix addresses issues related to multi-hash handling in LUKS2 and KeePass (KDBX4). Single-hash cases were not affected.

It also includes some other minor changes.

If you are looking for release notes please refer to docs/changes.txt.

RE: hashcat v7.1.0 - atom - 08-23-2025

Welcome to the hashcat v7.1.2 release!

This hotfix restores backward compatibility in machine-readable status view mode, which was broken in v7.1.0 and affected third-party overlays such as the Hashtopolis agent. It also fixes issues in the Argon2 libraries when used in multi-hash modes. If you are using hashcat v7.1.0+ with LUKS2 or KeePass KDBX4, updating is strongly recommended.

The release also introduces a new assimilation bridge plugin, the Rust bridge. Just like the Python bridge plugin, which lets you write hash-mode extensions in Python instead of C, you can now do the same in Rust. This is a valuable community contribution that will be covered in more detail in the next release notes. The feature is already fully functional and ready for early adoption, with initial documentation available in hashcat-rust-plugin-requirements.md.

For the full list of changes, please see docs/changes.txt.
