Md5 Amp; Sha Checksum Utility 2.1 Download
Poppy Yentsch
\t \tRaymond Lin's MD5 & SHA-1 Checksum Utility is a standalone freeware tool that generates and verifies cryptographic hashes in MD5 and SHA-1. Cryptographic hash functions are commonly used to guard against malicious changes to protected data in a wide variety of software, Internet, and security applications, including digital signatures and other forms of authentication. Two of the most common cryptographic hash functions are the Secure Hash Algorithm (SHA) and Message Digest Algorithm-5 (MD5). Checksum utilities are used to verify the integrity of generated hashes. There are two basic types, those that calculate checksum values and those that also validate them by checking them against a list of values for the protected data, which is the only way it can be done.
\t \tMD5 & SHA-1 Checksum Utility is free to download and use, though Ray accepts donations from satisfied users. At a mere 57k, his checksum tool is about as small as a useful, functioning utility can be in this age of bloatware, and even more so considering that it's certified to work in Windows Vista and 7.

Update: I had also checked Is there a built-in checksum utility on Windows 7?, however, that's an old question and does not specifically asks for CRC-32 and Windows 10 may have support for it now. That's why asking this.
Is there a windows program (preferably with a GUI for convenience) by any chance that can calculate checksums for entire folders of files and dump that to a text file (or something similar), then in the future be able to ingest that text file to verify all the checksums semi-automatically?
MD5 is a cryptographically insecure hash, so using a newer and more secure checksum is typical when security is a concern. (There are various reasons to use MD5, including protection against innocent corruptions and protection against attack. MD5 works for the former, but would not be my choice for the latter.)
Thanks Hoff for your response. I have installed ZIP already, but it doesn't have a checksum option. The checksum is simply to verify that the file transfered 100% correctly, before attempting to process it. I do see that Gzip has a checksum option so i might try this. I also saw GnuPG as an option, but gzip looks to be the easier of the two to install.
This may depend on the type of file you want to transfer. For example, a "text" file may be in VAR or VFC record format on VMS, but will be silently converted to STM or STM_LF record format when copied elsewhere. If your checksum utility includes meta data, the two versions of the file will generate different checksums.
recently i upgraded my ST-Link Utility from v3.8.0 to v4.2.0, within that change the value of the calculated checksum for the same Intel-HEX files changed. Below there are screenshots for the different ST-Link Utility versions respectively. In the change-log of ST-Link Utility i did not found information regarding a change in checksum calculation.
You can also verify the file integrity of the downloaded document or program. File Checksum Utility is very easy to use. From the graphical user interface, choose the file or the directory from your computer storage. The tool calculate and display checksum values. You can copy the results to the clipboard or export it to a CSV, XML or TEXT file. The main supported algorithms include MD5 (Message Digest number 5), SHA-1 (Secure Hash Algorithm level 1), SHA-256 and SHA-512.
You can verify it by choosing "Verify..." from the "Images" menu in Disk Utility. In Disk Utility you can disable checksum verification in the program's preferences settings. While in many cases a faulty checksum might be as simple as a metadata change for the file or its contents, or the developer forgetting to update the disk image's checksum after such a change, it could be from a more serious change that could result in corrupted files. This is why it's better to check the image and ensure its data organization is as the developer intended it to be received.
innochecksum prints checksums for InnoDB files. This tool reads an InnoDB tablespace file, calculates the checksum for each page, compares the calculated checksum to the stored checksum, and reports mismatches, which indicate damaged pages. It was originally developed to speed up verifying the integrity of tablespace files after power outages but can also be used after file copies. Because checksum mismatches cause InnoDB to deliberately shut down a running server, it may be preferable to use this tool rather than waiting for an in-production server to encounter the damaged pages.
innochecksum cannot be used on tablespace files that the server already has open. For such files, you should use CHECK TABLE to check tables within the tablespace. Attempting to run innochecksum on a tablespace that the server already has open results in an Unable to lock file error.
Ignore the checksum verification when rewriting a checksum. This option may only be used with the innochecksum --write option. If the --write option is not specified, innochecksum terminates.
The maximum number of checksum mismatches allowed before innochecksum terminates. The default setting is 0. If --allow-mismatches=N, where N>=0, N mismatches are permitted and innochecksum terminates at N+1. When --allow-mismatches is set to 0, innochecksum terminates on the first checksum mismatch.
With --allow-mismatches set to 1, if there is a mismatch at page 600 and another at page 700 on a file with 1000 pages, the checksum is updated for pages 0-599 and 601-699. Because --allow-mismatches is set to 1, the checksum tolerates the first mismatch and terminates on the second mismatch, leaving page 600 and pages 700-999 unchanged.
Rewrite a checksum. When rewriting an invalid checksum, the --no-check option must be used together with the --write option. The --no-check option tells innochecksum to ignore verification of the invalid checksum. You do not have to specify the --no-check option if the current checksum is valid.
Log output for the innochecksum tool. A log file name must be provided. Log output contains checksum values for each tablespace page. For uncompressed tables, LSN values are also provided. The --log replaces the --debug option, which was available in earlier releases. Example usage:
Running innochecksum on multiple user-defined tablespace files is not supported on Windows operating systems, as Windows shells such as cmd.exe do not support glob pattern expansion. On Windows systems, innochecksum must be run separately for each user-defined tablespace file. For example:
The three files (ibdata1, ibdata2, and ibdata3) form one logical system tablespace. To run innochecksum on multiple files that form one logical system tablespace, innochecksum requires the - option to read tablespace files in from standard input, which is equivalent to concatenating multiple files to create one single file. For the example provided above, the following innochecksum command would be used:
Running innochecksum on multiple files in the same tablespace is not supported on Windows operating systems, as Windows shells such as cmd.exe do not support glob pattern expansion. On Windows systems, innochecksum must be run separately for each system tablespace file. For example:
Go to the LibreOffice download page and copy one of the official checksum numbers for the file you downloaded. Of the checksums that LibreOffice offers SHA-256 is the most secure to use. VERY IMPORTANT: When copying the checksum number be absolutely sure that you copy only the number, do not copy any spaces, they are not part of the number.
With KDS Kinetis Design Studio (KE06Z processor) we've created a boot loader that verifies the main execution code with a checksum, before running it. However the tool that computes the checksum and adds it to the binary file, can't run till the linker has finished - and therefore the checksum cannot be in the linker output file that the debugger uses.
On KDS we have a solution using the "specify additional ELF file" feature which sets the debugger to load a checksum file in addition to the main (elf) debug code - see screenshot. I think I got this from Erich Styger / MCUonEclipse (but I can't find it there today).
The LPC parts use a checksum word located at a specific offset in the vector table. This is simply a two's complement of the first 7 vector entries. The LPC boot loaders use this word to determine whether a valid user image exists before it loads the reset context. The LPC parts mostly use vector 7 (offset 0x1C), an unused vector location to store the checksum word. There were exceptions. If this is sufficient for your purposes, you'll find the checksum.exe utility in the MCUXpresso installation. Otherwise, it's a fairly trivial matter to write your own utility.
