About this utility
How to use Hash Identifier & Multi-Checksum Verifier
Calculate CRC-32, MD5, SHA-1, SHA-256, SHA-384, and SHA-512 for one file and verify a pasted checksum manifest.
What to provide
Drop the file to hash. It remains in memory and is never uploaded.
Paste one digest per line, optionally prefixed by algorithm and : or =. Length-based candidates are shown when unnamed.
- Choose or drag the local file into the clearly labeled drop area.
- Place the second value or file in the adjacent panel. Sensitive fields are masked by default.
- Review the input and the clearly labeled output behavior.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
Calculated digests, likely algorithms, and explicit matches or mismatches.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- Everything is processed in this browser tab. Input, filenames, keys, and output are never uploaded or saved. A matching hash proves only byte equality with a digest from a trusted channel. MD5 and SHA-1 are legacy-only.
