Integrity

Cross platform command line tool for storing, displaying and checking a file's checksum.

Check your files have not become corrupted over time.

Features

• Supports Linux, FreeBSD and OSX
• Checksum data is stored in the file's extended attributes so moves with the file.
• Multiple checksum algorithms available (defaults to sha1)

MD Functions	SHA Functions	SHA3 + SHA512 Functions	Blake Functions	File Type Specific Functions
md5	[sha1]	sha3 224	blake2s 256	phash (images)
md5sha1	sha224	sha3 256	blake2b 256	ohash (videos)
	sha256	sha3 384	blake2b 384
	sha384	sha3 512	blake2b 512
	sha512	sha512 224
		sha512 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

Custom Checksum Usage Examples

Add a phash checksum verbosly to an image using the phash binary

integrity.phash -v -a image.jpg

Add a blake2b_256 checksum verbosly to a file

integrity --digest blake2b_256 -v -a file.dat

Alternatively the Environment variable INTEGRITY_DIGEST may be used

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

List all potential checksums stored with a file

integrity -l -x file.dat
