Documentation

Generate CRC-16 hash from input string or bytes.

This transform computes the crc-16 hash of the input text and returns the hexadecimal digest string. The input can be any string or bytes-like object.

Notes:

• Returns a 4-character hexadecimal string if ‘H’ flag is set, otherwise returns an integer
• Input is encoded as UTF-8 if not already bytes
• Not suitable for cryptographic purposes (use stronger hashes for security)
• Consistent output for same input across different platforms

Flags

Flag	Letter
noncaptive_input	I
hex	H

Examples

Basic hashing

Input args: ["hello"]
Transforms: "crc16:"
Output: 50018

With bytes input

Input args: ["hello"]
Transforms: "crc16:"
Output: 50018

With hex output

Input args: ["hello"]
Transforms: "crc16(1H):"
Output: "c362"
