Adler32 commandline utility


adler32 – Calculate Adler32 checksum of a stream of data.




This program takes as input an arbitrarily long stream of bytes and outputs a single hexadecimal Adler32 checksum. It is intended as an alternative to CRC-based checksums which may run a little slower.

All actual computation is performed by zlib.


$ echo test | adler32
