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.

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.

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.

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.

This program doesn't simply check file integrity, it also lets you restore files that have been damaged using data redundancy. While very useful for archive purposes, users should realize this ADDS a percentage of data to the archive. A 1.5 gig archive took up 422 megs with default settings.

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.

A little intimidating at first, but so far looks like the best file verification tool I've tried yet. Fast, recursive directory verify, open source, relative pathways, and multiple different verification methods? Dream come true for making sure your data hasn't changed or corrupted. Recommend MD5 for general file verification and SHA 256 for security verifications.

Doesn't convert both hashes to upper or lower case, so if your MD5 hash is uppercase, it will say they don't match even though they do. |
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.
