Files - Integrity Checkers (19)

RapidCRC Unicode is a hashing program capable of checking and verifying the integrity of files, folders, or whole drives. The program includes process priority, ability to pause/resume analysis, job queuing, easily copy hashes to the clipboard and multi-threaded checks. If using checksum files (e.g. .sfv or .md5) for future verification, options include the ability to generate for every analyzed file, directory, or a single checksum with all hash data.

Includes direct support for CRC hashing in the filename (common for anime releases) for example: "MyFile [45DEF3A0].avi") Other algorithms range from fast to secure, including SFV(CRC32), MD5, ED2K, SHA-1/256/512 and Blake2sp.

Based on the original RapidCRC but updated with extended Unicode support.

MultiPar helps protect backups and transfers with error detection and recovery. The program looks at information from any number of files and folders to function as insurance against data loss. The program generates companion "PAR" files that are built from a percentage of the originals, using more space for greater protection (e.g. 10% of the original for already safe methods, 50% for frequent failures).

The program has a wide variety of customizations including format, processor usage, and various other tools available to the standard PAR format. For backups, it can also choose PAR size by available free space (e.g. saving a 3 gig file to a 4.7 gig DVD will mean generating a 1.7 gig PAR file).

Functional in Linux/Mac via WINE. The program supports multi-threading, multiple processors, can recurse subfolders, and functions with standard formats including PAR, PAR2, and (experimental) PAR3 formats.

HashMyFiles is a small utility that allows you to generate unique file identifiers (hashes) using a variety of popular checks. These can help determine if a file has been modified or corrupted, as well as help determine the file's reputation by submitting to the VirusTotal database for malware analysis.

Formats supported range form fast to secure with CRC32, MD5, SHA1/-256/-512/-384. The various hashing information can be saved to a report (text/HTML/XML/CSV/TSV) that includes name, path, dates, file size, version and other info.

RekSFV is a checksum generator and verifier that can evaluate files and whole directories. When scanning, the program checks for all supported files and verifies any found checksums. The program supports drag and drop, stay-on-top, minimize to tray, shortcut keys, multiple instances, sound notification and more.

The program supports several hashing algorithms including SFV, MD5, SHA1, SHA256, SHA512.

IgorWare Hasher can be used to generate a checksum for a single file or verify its integrity using verification files (.sha, .md5 and .sfv) generated by many hashing programs. The program supports UTF-8 verification files and are automatically verified if found.

CRC32, MD5 and SHA-1 hashes are supported.

MultiHasher is a drag-and-drop tool for creating and checking file hashes, useful for checking data integrity. The program will check files, folders and even text using a variety of methods with both pause and cancel options for large operations. The program can then compare digests to detect changes as well as query the result to the VirusTotal database. A search tool lets you quickly track down both files or specific hashes from long lists.

A recursive checking option (entire directory trees) is available in the options menu. The program can also use existing, standard hash files such as MHX, SFV, MD5Sum etc. to check integrity.

Supports 64-bit operating systems and available algorithms include from fastest to most secure: CRC32, MD5, RIPEMD-160, SHA 1, 256, 384 and 512. Can include one, some, or all algorithms available in testing.

SFV Ninja allows you to check the integrity of any number of files. After running on a file list, the program can then check all files on that list, with the option to only verify/update only newly added files. The program can recursively scan/generate a folder for files and load them all at once, using relative paths whenever possible.

Useful to quickly checking system files or archives for modification/corruption. Supports many commonly-used hashing algorithms listed here from fast/simple to slow/secure: SFV (CRC32), MD5, SHA-1, and SHA-256.

Fsum Frontend allows to compute message digests, checksums, and HMACs for files and text strings. It supports drag-and-drop and can function on batches of files at once either for creation or verification.

The program supports a host of different hashes including common like CRC32, MD5, and SHA256 as well and many obscure hashing methods (96 total). Allows both batch creation and verification.

As the name implies, the program uses FSUM.

MD5Checker is a fast and lightweight tool to calculate and verify MD5 files hashes of multiple files and folders. Calculated MD5 File hashes can be saved and loaded to/from files.

Note that a separate download is available from the website for Win9x/Me.

MD5 Checksum Tool is a drag-and-drop hash checking tool that can generate a file checksum to analyze if a file has changed, usually to affirm it's legitimate and uncorrupted. The program can scan a folder and subfolders (recursively), as well as provide a report of all files, their size, and checksums. Supports very large files (4GB+) and includes a progress bar to estimate remaining time.

The program will allow the comparison of two files with their respective checksums and supports MD5, SHA1, SHA256, SHA384 and SHA512 checksums.

A 64-bit version is available (within the x64 folder).

SendTo MD5 is a small utility to calculate and compare MD5 checksums of files or strings. You can easily check the integrity of files, compare different MD5 hashes or simply check if two files are identical. Additionally, you can search files with specific MD5 hash and benchmark the time it takes to calculate MD5 hash from specific file.

ICE ECC is a file verification and repair tool that works to ensure files are backed up or transmitted. In the event of a failure or damaged media, the program can help recover data lost to corruption. The program works on individual files or entire folders.

Uses a fast implementation of Reed-Solomon codes.

HashCompare helps verify files via drag-and-drop interface using any of the the popular hash algorithms MD5, SHA1 or SHA256. Can quickly drag one or both files for analysis and save reports to XML/HTML/text.

Quick Checksum Verifier checks file integrity with standard algorithms like MD5 and SHA-1. Also supports command-line arguments.

64-bit version available from website.

FileVerifier++ checks and compares files to see if they have been modified. Supports drag-and-drop, recursive directory processing, patterns, color coding, export to a variety of hashing formats (.sfv, .md5, .csv, etc.) and more. Can use any of 21 different hashing algorithms such as CRC16 for speed and SHA-512 for security (uses the standard MD5 by default).

The program (ZIP version) will automatically ask to create verification files with relative pathways, which is much more portable.

Win2K users should use an earlier version. A beta 64-bit version is available.

DVDsig scans all files in a directory structure to verify that files have not been changed or corrupted. Although named for checking external media (DVDs), the program can monitor any folder or folders for changes.

For use with CD/DVDs:

1. Place dvdsig.exe in the top-most folder you wish to check and run the program
2. Click "Scan" and wait for the check program to check all files
3. Burn the files (including dvdsig.exe and dvdsig.md5) to your disk
4. To check the results, run dvdsig.exe from the disk at any time to verify file integrity

MD5 Checksum Calculator is a small, simple utility for calculating and comparing the MD5 checksum values of specified files.

CheckFolder validates the integrity of files in a folder or drive. Can check any type of media for problems, but especially useful for checking if a scratched or newly-burned CD or DVD is readable.
