Calculate Fletcher-32 from text and copy the 8-character hexadecimal result. This variant processes UTF-8 bytes as 16-bit words.
If the input has an odd number of bytes, the final byte is padded with zero for the last word. That detail can affect comparisons with another implementation.
Fletcher-32 is an error-detection checksum. CRC profiles are more common when a standard names a polynomial and exact initialization rules.
Fletcher-32 returns a 32-bit checksum, usually written as 8 hexadecimal characters.
Paste text into the input pane. Batch mode calculates one Fletcher-32 value per line.
The final byte is paired with a zero byte so the input can be processed as 16-bit words.
Calculate CRC, Adler, Fletcher, BSD, and System V checksums for text input. Batch mode processes one value per line.
Calculate bitwise AND, OR, XOR, NOT, and shifts on fixed-width integers. Choose the word size, input base, and signed result display.
Generate placeholder text for layouts. Customize the paragraph count, line length, and copy the exact Lorem Ipsum needed.
Generate aHash, dHash, pHash, and wHash fingerprints for JPEG, PNG, and WebP images. Set hash size, copy values, and export results as a CSV.
Calculate the duration between two date-time values. Show the result in milliseconds, seconds, minutes, hours, days, weeks, average months, or average years.
