SB-SHA1 Checksum Calculator - Freeware

SB-SHA1 Checksum Calculator is a tool to calculate and compare the SHA1 checksum of files. The SHA1 is a 160-bit hash function which resembles the earlier MD5 algorithm. This was designed by the National Security Agency (NSA) to be part of the Digital Signature Algorithm.

How to use SB-SHA1 Checksum Calculator.

Here is the main screen:

How do you get an SHA1 checksum of a file?

Press the Browse button. This will allow to to select a file:

I will select SetupMD5.exe.

You will notice in the MD5 field the value 51e47833d0e42a90b84f37f8456b1a0f2601c6eb This is the SHA1 checksum value.

2. I can compare the SHA1 checksum value with another file to see if they are the same. Press the Compare button this will allow you to select a file to compare with:

In this case, I will select the same file SetupMD5.exe

You will notice that SHA1 checksum value of the file I just selected turned green. This indicates that the files are the same. If I were to select a file that was slightly different, it would have turned red:

If I happened to copy to the clipboard an SHA1 value, SB-SHA1 will automatically check if the SHA1 values are the same with the first file you selected:

What do the other options do?

If you check the Show results in upper case checkbox, SB-SHA1 will display the SHA1 checksum values in upper case.

If you press the Clear button, all the fields will be cleared out and ready for new files to calculate SHA1 checksums.

If you press the Exit button, SB-SHA1 will exit back to Windows.
