Perks is a lightweight Windows command-line tool for generating and verifying file hashes (MD5, SHA1, SHA256, SHA512) across directories with checksum persistence.

Perks.exe -[md5|sha1|sha256|sha512] [path] [-f/--file <file.perks>] [-l/--logfile <file.log>]
Perks.exe -v/--verify [path] [-f/--file <file.perks>] [-l/--logfile <file.log>]

• -[md5|sha1|sha256|sha512] Specify the hash algorithm to use
• -l, --logfile <file> Specify log file (default: perks.log)
• -v, --verify Verify files against a previously generated hash file
• -f, --file <file> Specify input/output file (default: .perks)
• -n, --nobanner Suppresses the banner output
• -h, --help Displays the help menu

# Generate SHA256 hashes of current directory
Perks.exe -sha256
# Generate MD5 hashes with custom output file
Perks.exe -md5 C:\MyProject -f project_hashes.perks
# Verify files against hash file
Perks.exe -v C:\MyProject -f hashes.perks
# Suppress banner output
Perks.exe -n -sha256 C:\MyFolder

• Uses Windows CryptoAPI (wincrypt.h) for native hash computation
• Supports multiple algorithms: MD5, SHA1, SHA256, and SHA512
• Stores hash algorithm metadata in output files for automatic detection during verification
• Provides detailed verification reports with pass/fail status and summary statistics
• Implements a robust CLI argument parser with intelligent defaults
• Handles long file paths with extended buffer support
