• Multiple checksum algorithms available (defaults to sha1)
  • md4
  • md5
  • sha1
  • sha224
  • sha256
  • sha384
  • sha512
  • md5sha1
  • ripemd160
  • sha3 224
  • sha3 256
  • sha3 384
  • sha3 512
  • sha512 224
  • sha512 256
  • blake2s 256
  • blake2b 256

Simple Usage examples

Add checksum data to a file

integrity -a file.dat
file.dat : sha1 : added

Display checksum data stored with file

integrity -l file.dat

Validate the file still matches the stored checksum

integrity -c file.dat

Advanced Usage Examples

Add a sha256 checksum to a file

integrity --digest sha256 -a file.dat

Alternatively the Environment variable I_DIGEST may be used

export I_DIGEST="sha256"; integrity -a file.dat

List all the checksums stored with a file

integrity -l -x file.dat
