Adler32 Checksum Generator

 

What is Adler32?

It's a 32-bit checksum algorithm, a modification of the Fletcher checksum. It was invented by Mark Adler and is part of the commonly-used zlib compression library. It has the same length as CRC32, but it's faster. This hash function has also a weakness - checksums for very short messages have a poor coverage of the available bits.

The above Adler32 generator converts a string into a hash value. For example, if you type:
"Adler32 Hash"
in the input field above and submit you get a digit:
f2037b19.
But even a small change in the text will result in a completely different Adler32 hash. For example, if you type:
"Adler32 hash"
and submit form then you get a completely diffrent hash:
1204fb19.
