Hello,
I know 7-zip already has some checksum feature, including CRC, SHA, and BLAEK.But, maybe you can also add MD5 checksum support.I think it is used quite often.Thank you.
Regards,William.
MD5 will be a nice touch if you add it , but isn't really that imprtant many still use it though
And maybe a new sub-context menu to save all checksum as a .txt file even i do find copying the text from the message is enough :)

As a genuine Windows ISO files collector, any hash programs that support CRC32 + MD5 + SHA1 will be favored. Don't care about today's hash standard (sha1 + sha256 + sha???).
Sigcheck is an alternative utility that can calculate file hashes (md5 + sha1 + sha256).

Note that I don't need artificial examples.
You already wrote about your cases.
So it's interesting to know answers from another users that request that feature.
And sf example shows that we don't need md5 - we have sha1 that is more safe.
Some notes about hash in 7-Zip:
crc32 - very fast, is used everywhere
crc64 - is pretty fast, is used in xz, and provides higher level of error detecting than crc32.
sha1- is safe (for some purposes), is used in many places
sha256- is safe, is used in many places
blake2sp - I need it only for RAR5 code.
md5 - the speed is similar to sha1, is not used in popular archive formats. Probably it will be replaces to sha1/sha256 in cases, where it's still used, is not so safe as sha.

Copying to clipboard just one checksum instead of this "--- Checksum Information ---" could be more useful. So I think checksum is better to be selectable.

While we are discussing checksums, can you actually make them copyable with mouse. Currently there seems to be no way to copy the checksums into clipboard.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I agree it would be nice to have some buttons to copy the checksums to the clipboard. I know Windows allows Ctrl+C from any MessageBox but not many people know about that.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
1) Please make an opportunity to highlight and copy the hash sum from MessageBox after counting. At this time it is very inconvenient. I calculated a hash and I cannot check it by virustotal neither post it on forum or anywhere.
2) Also I support the request to calculate MD5 hash. Example of the place where I constantly need MD5 hash is logs of AVZ. So only this hash sum used there.
Thank you.

7zip 18.05 changed the control from message box to checkbox.
You can now select a single (or more) lines and use copy + paste (you don't get the control output of a message box, if you only select name+size+sha1 only those will be pasted as separate lines to the clipboard).
I want to raise the MD5 request again - it it not needed to pack/unpack but still used in different places and therefore good to support (MD5 is the only reason that I need to open Sigcheck all other checksums are handled via 7zip). RFC1321 provides both the "MD5 Algorithm Description" and an implementation in plain C.

MD5 is broken for many years already. SHA1 is declared broken deprecated as well. Do you really want broken checksums in such a good software? What's the advantage? I'd rather add more modern and more secure SHA-3 checksum than crappy old piece of junk...

I don't use md5. So I'm not sure that md5 is useful.
Where do you need to use md5?
MD5 will be a nice touch if you add it , but isn't really that imprtant many still use it though
And maybe a new sub-context menu to save all checksum as a .txt file even i do find copying the text from the message is enough :)

и таких случаев можно привести еще множество. Надо?

BTW, it will be nice to make generated checksum selectable (to copy it).
Or just add the button like "Copy to clipboard"
Well if you simply press Ctrl + C on after the checksum information show up you will get in your clipboard
Example

Zipware can md5.

WinCryptHashers plugin for 7-Zip allows you to calculate MD5 directly in 7-Zip.

Jesus, just use HashCheck!
