Files - Integrity Checkers (19)

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.

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, SHA-256 and SHA-512.

A 64-bit version is available on download page. Based on the original RapidCRC but updated with extended Unicode support.

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.

CHK is simple checksum program that can verify downloaded files from the Internet, hash your files to ensure integrity and help detect duplicates. Supports drag-and-drop and most popular hash protocols including CRC-16/32/64, ED2K, MD4/5, SHA-1/256/512/3 etc.
