HashMyFiles by nirsoft offers both those options BTW. My most frequent use for hashing programs is finding duplicates. Si I'm using HashMyFiles. It also has a add to context menu option.

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.

This is currently my go-to program. I tend to add it to the "send to" menu on machines I'm currently using and it works beautifully to check one or more files. Also, the ability to insert the hash directly into the file name makes so much sense. Just drag-and-drop it into the window and instantly know if there's a problem. Great solution to the multi-step check.

I think there is something wrong with the "CRC into Filename" function. This occurs with files that lack a file extension.

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.

@Multiparuser: if you go to the page we link to when you click "website" you can see what the author has posted about the .EU mirror, which is encouraging caution. He does not call it a malicious spam site. |
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.

Blows my mind how stagnate NirSoft's programs become, HashMyFiles still doesn't have a way to "Delete files to Recycle Bin" or similar. And all his programs are still plagued with DPI/multi-monitor issues years after reporting about them.

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.

I agree that HashMyFiles is the best one for multiple files I have found to date. It's small, quick and even integrates into the right click menu if you want it there.

Works great to create/verify companion hashes for individual files. Wish there was a way to work in a batch mode. |
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.

Two bugs to be aware of. The first bug is: |
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.
