Adler-32 Hash Generator

What is Adler-32

In 1995, Mark Adler developed the Adler-32 checksum algorithm, which is a modification of the Fletcher checksum. When compared to a cyclic redundancy check of the same length, it sacrifices reliability for speed. Fletcher-16 is considered to be more trustworthy than Adler-32, but Fletcher-32 is slightly less trustworthy.

Mark Adler created the Adler-32 checksum as well as the widely used Zlib compression library. Calculating two 16-bit checksums A and B and concatenating their bits into a 32-bit integer yield an Adler-32 checksum. A is the sum of all bytes in the stream plus one, and B is the sum of each step's individual values of A.

Calculating the Adler-32 hash of a string is not something that one can be done manually because hashing a string is a very complex and tedious process. That is where our online Adler-32 hash generator tool comes into play.

We have so many methods and tools available to calculate the Adler-32 hash of a string, but not every online tool gives an accurate result and that is why we have created this online Adler-32 Hash Generator tool. It is a very simple and easy-to-use tool. Most important thing is that it is beginner-friendly.
