Choose your certainty
Proof for every kind of job
From a quick check in the field to full byte-for-byte verification for work you cannot afford to lose.
Standard
Samples the actual contents of every file. Catches renamed copies and stays practical on a NAS.
CONTENT SAMPLES · SHA-256Paranoid
Reads every byte of both copies for the jobs where “almost certain” is not enough.
FULL-FILE SHA-256Camera counters recycle file names. Content matching is the proof that counts.
