MD5/SHA1 checksum
An enhanced file checksum plugin for the Total Commander
(TC for short). It supports both MD5 & SHA1 algorithms, and is able
to checksum the entire directory trees. Note that it's MD5 checksum
function is much faster than TC's internal one (70% faster on my Athlon
XP 1700+ with Seagate IDE 160 GB 7200 rpm HD!). Both MD5 & SHA1
algorithms were ripped from PuTTY by
Simon Tatham, who implemented them directly from the specification.
Basically, the file checksum plugin integrates the functionality of GNU utilities
Note that as TC runs on Windows, checksum plugin will use DOS line endings (CRLF). To
"export" the generated checksum list to a UN*X system, you can use my ToFroWin utility, which also integrates itself into TC 
Then, to verify files consistence from TC, select

same, just replace every "md5" you see by "sha")
Basically, the file checksum plugin integrates the functionality of GNU utilities
md5sum and sha1sum
into the Total Commander GUI. This is done through the packer extension
API: you simply select files/directories you want to checksum, and
"Pack" (Alt+F5) them into a .md5 or .sha "archive". It will be a plain text file which looks like this (just the same format as that of above GNU utilities):3fb2924c8fb8098dbc8260f69824e9c437d28c68 FC4-i386-disc1.iso

Then, to verify files consistence from TC, select
.md5 or .sha
file and "Test archive" (Shift+Alt+F9). Files generated by *BSD md5 utility are also supported. You can also browse checksum
files as they were directories; this is specially useful to locate
and check for consistence a single file from the huge directory tree.
To do that, just "View" (F3) a file, and TC Lister will pop you a
window with content like this:D:\_INSTALL_\stentz-binary-i386\FC4-i386-rescuecd.iso
expected: 736e1555e88740d6131c5c84fbe69ed1073ba82d
computed: 736e1555e88740d6131c5c84fbe69ed1073ba82d
SHA1 checksum OK!
Installation:
- Unzip the
"checksum.wcx"to the Total Commander or Windows Commander plugins directory - In Windows Commander 4.0 (or newer) or Total Commander, choose 'Configuration => Options'
- Open the 'Packer' page
- Click 'Configure packer extension WCXs'
- Type
md5as the extension - Click 'New type', and select the
"checksum.wcx"file - Click OK and then 'Configure packer extension WCXs'
- Now type
shaas the extension - Click 'New type', and select the
"checksum.wcx"file again - Click OK
Usage:
(This section uses MD5 checksums as example; for SHA1 the procedure is thesame, just replace every "md5" you see by "sha"
)- Generate MD5 checksum:
- Select files you wish to compute checksum.
- Then go to "Files => Pack".
- Select "md5" as packer.
- PLEASE NOTE THAT ARCHIVE PATH WILL BE IGNORED!!! ".md5" 'archive' is ALWAYS generated in current directory (where checked files are), and NOT in the opposite panel! The only exception is creating checksum of the files stored on CD-ROM media as there's no way to create files there.
- Press OK and check CURRENT directory for ".md5" list generated.
- Verify MD5 checksum:
- Certify that ".md5" list is in it's right place (filenames listed in it should be relative to the current directory).
- Select it and do "Files => Test Archive(s)".
- If any file doesn't matches stored MD5 checksum then "CRC error" message box appears.
- If everything is clear Total Commander remains quiet.
- Browse MD5 checksum list:
- Certify that ".md5" list is in it's right place (filenames listed in it should be relative to the current directory).
- Select it and enter it as it were a normal archive.
- If any file is present in the ".md5" list but wasn't found in the current directory then "?" is displayed instead of file date/time and size.
- PLEASE NOTE THAT FILES CAN NOT BE EXTRACTED TO YOUR DISK! ".md5" isn't an archive, it stores only the hash of the file.
- Select file you wish to check and press F3 (call Lister).
- Lister will show complete file name, expected checksum and generated checksum. If both checksum matches then the last line is "MD5 checksum OK!".
