go library to ease work with hash algorithm

Go checksum

Command line and library to manage files integrity checksums

As lib :

• Support plenty of algorithms
• Dynamic algorithm creation and usage
• Ease hashing usage of readers and files
• Can create binaries like sha*sum with few lines of code
• Create easily checksum files
• Detect checksum files
• Validate files against detected checksum

As a binary :

• mimic sha1sum but for all algo
• process directory trees to
  • set sum in a sumfile or in the filename
  • set watch tree for new file and set sum
  • check that sum is valid
  • remove sum from sumfile or from filename
  • list files that will be processed

configuration file :

pattern: (?i)\.*$         # pattern for files to process
patternIsExclusive: true  # use pattern as inclusive or exclusive
hash: sha1
strategy: sumfile        # `sumfile` or `filename` store sum to a sumefile and directly in the source filename

# work like `sha1sum`
fi sum -H sha1 testfile.txt


# list files that will be hashed and checked
fi -c ./checksum.yaml list test/
# set sum to filesum or filename
fi set test/
# watch for new files in the tree and set sum
fi set watch test/
# remove filesum or sum from filename
fi remove test/
# check that sum matches file
fi check test/
