CHK v1.12 is here!

[encode]

What's new:

• Added ED2K hash
• Added "Uppercase" option
• Removed "List View" feature
• Improved Hash Input box. Now it features Paste button and parses the input
• Added UTF-8 support for hash lists. Changed hash list layout
• Changed Clipboard hash layout
• Some GUI improvements
• Now CHK's executable is not packed (since UPX crashes on my system)

Please enjoy a new release!

Blake2 should be a good addition to CHK. See here: https://blake2.net/

The chk112.7z archive contained only an .exe.
Is this a Windows-only freeware?

Yep!

[hofner]

wow, that was pretty quick reply. As the page listed few sourceforge projects, i was about to search chk there.

Sad thing that i cant try out, it being Windows-only.

Wasnt sure earlier if wine would run it. But, it did.

MD4 = ED2K ?

[encode]

MD4 = ED2K ?

For relatively small files (<=9500KB) - yes. Otherwise the answer is no.

ED2K hash algorithm

Uploaded a 64-bit compile: http://encode.narod.ru/

Currently working on a new release - CHK v1.20:
+ Replaced simple "Add..." menu with
"Add Files..."
"Add Folder..."
+ Now "Copy Hash" copies to Clipboard a hash string only (Instead of "Filename, Hashtype: Hash")
+ Removed timer. Now displaying the file names with full path during process
+ Renamed the hash list to:
CRC-16
CRC-32
CRC-64
ED2K
MD4
MD5
SHA1
SHA2-256
SHA2-512
SHA3/KECCAK-512

Thinking about to add "SHA1-BASE32" ("URN:SHA1")...

If you have any suggestions/ideas for the new release - feel free to post it here!

Dear Mr. Encode,

I prefer or suggest command line interface. And ability to calculate check sums from files "hidden" in various archives. And ability to compare two directories against each other.

Best regards,

FatBit

+ SHA-384
+ [Paused] state (If you move the window during file processing)
+ Clicking on an empty window opens "Add files" dialog

Added RIPEMD-160, feeling overloaded with hash functions. Still can't get the logic of this stupid compiler - simply adding SHA-384 affects the performance (and even single-file performance) of other hash functions... Continue coping with this s....

[encode]

RIPEMD-160 is about two times slower than SHA-1 and somewhat less popular. The main reason guys using it is because of its non-NIST origin.

[encode]

Yes, now you can move the columns as you want!

Thinking about to add "SHA1-BASE32" ("URN:SHA1")...

that's a good ideea!
- Also you may add on right click menu "copy magnetlink" (also generate a magnetlink for file/s) for ed2k/sha-1/md5 hashes.
- allow selecting multiple files (copy hashes)

[encode]

And this is how it looks. Super-cool!
Actually, I dislike "SHA-1 (Base32)" naming. Thinking of "Magnet", G2 (Gnutella2 hash) or something like this. Also this can be the default hash - since it is more readable and cool than hex representation!

[encode]

A proposed shortened hash list:

[DaFixzer]

Nice Work,

Do You think it's a good idea if you make the hash menu work like Checked Menu instead of Options,

So When I check for Example MD5 and CRC32, a new column added to the list view and Calculate the Second selected Hash.


FileName | MD5 | CRC32 | FilePath
-------------------------------------------
Boo.txt... | ........ | ........ |
-------------------------------------------
..............| ....... | ......... |
-------------------------------------------
..............| ....... | ......... |
-------------------------------------------
..............| ....... | ......... |

I've tested that "individual hashes" idea many times. It would be a mess, believe me.

+ Optimized all hashes (Everything runs slightly faster)
+ Insanely optimized CRC32 (Slicing-By-4 trick)

Some timings for CRC32 on ENWIK9:

Current CRC32 - 2.9 sec
If outsmart, outwit that vicious compiler - 1.9 sec (As it should be with a good compiler)
CRC32 with Slicing-By-4 trick - 0.8 sec [!]


I think I will stay with this hash list (the default hash is SHA1):

The sort arrow, at last!

The sort arrow, at last!

Cool!

7-zip crc32: 2gb/sec
crcutil: 4gb/sec
using clmul: 15-20 gb/sec

also, you can easily multithread crc computations to reach 100gb/sec
