Welcome to hashcat v4.2.0!

Download binaries or sources: https://hashcat.net/hashcat/

This release is mostly about expanding support for new algorithms and fixing bugs:

Thanks to @hops_ch for contributing the Ansible Vault mode!

Improvements:

Added JtR-compatible support for hex notation in the rules engine
Added OpenCL device utilization to the status information in machine-readable output
Added missing NV Tesla and Titan GPU details to tuning database
General file handling: Abort if a byte-order mark (BOM) is detected in a wordlist, hashlist, maskfile or rulefile
HCCAPX management: Use advanced hints in message_pair stored by hcxtools about endian bitness of replay counter
OpenCL kernels: Abort session if kernel self-test fails
OpenCL kernels: Add '-pure' prefix to kernel filenames to avoid problems caused by reusing existing hashcat installation folder
OpenCL kernels: Removed the use of 'volatile' keyword in inline assembly instructions where it is not needed
OpenCL kernels: Switched array pointer types in function declarations in order to be compatible with OpenCL 2.0
Refactored code for --progress-only and --speed-only calculation
SIP cracking: Increased the nonce field to allow a salt of 1024 bytes
TrueCrypt/VeraCrypt cracking: Do an entropy check on the TC/VC header on start

Notes:

The removal of 'volatile' keyword has a large positive impact on cracking performance on macOS
The refactored code for --progress-only is important if hashcat is used in combination with a distributed overlay such as hashtopolis

Fixed Bugs:

Fixed a function declaration attribute in -m 8900 kernel that led to unusable -m 9300 (which shares kernel code with -m 8900)
Fixed a miscalculation in --progress-only mode output for extremely slow kernels like -m 14800
Fixed a missing check for errors on OpenCL devices leading to invalid removal of the restore file
Fixed a missing kernel in -m 5600 in combination with -a 3 and -O if mask is >= 16 characters
Fixed detection of AMD_GCN version when the rocm driver is used
Fixed missing code section in -m 2500 and -m 2501 to crack corrupted handshakes with a LE endian bitness base
Fixed a missing check for hashmodes using OPTS_TYPE_PT_UPPER causing the self-test to fail when using combinator and hybrid modes
