- Prevent Hashcat from hanging by checking during startup that the output file is a named pipe
|
||||
- Fixed debug mode 5 by adding the missing colon between original-word and finding-rule
|
||||
- Skip generated rule that was the result of chaining rule operation and caused this generated rule to exceed the maximum number of function calls
|
||||
- Fixed incorrect plaintext check for 25400 and 26610. Increased plaintext check to 32 bytes for 25400 to prevent false positives.
