Hex Editor Neo provides a number of checksum calculation algorithms. All algorithms are capable of quickly calculating the result for the whole document, or only part of it. All checksum calculation algorithms fully support multiple selection.
The following section, Checksum Tool Window, describes the user interface window used to configure and start checksum calculation. Below is a complete list of supported algorithms.
The following algorithms are supported:
Algorithm | Notes |
---|---|
CRC-16 | Cyclic redundancy check. CRC polynomial: x16 + x15 + x2 + 1. Used in XMODEM, USB, many others. |
CRC-16 (CRC-CCITT) | Cyclic redundancy check. CRC polynomial: x16 + x12 + x5 + 1. Used in X.25, V.41, Bluetooth, PPP, IrDA, BACnet |
CRC-32 | Cyclic redundancy check. CRC polynomial: x32 + x26 + x23 + x22 + x16 + x12 + x11 + x10 + x8 + x7 + x5 + x4 + x2 + x + 1. Used in V.42, MPEG-2. |
CRC XMODEM | Cyclic redundancy check. CRC polynomial: x16 + x12 + x5 + 1. Used in XMODEM. |
Custom CRC | Allows you to specify the polynomial values used in checksum calculation. See the Configuring Custom CRC section for more information. |
Adler-32 | Adler-32 checksum. Used in zlib and others. |
Fletcher | RFC 1146. Fletcher checksum. |
The following algorithms are supported:
Algorithm | Notes |
---|---|
FNV-1 32-bit | 32-bit FNV-1 hash |
FNV-1a 32-bit | 32-bit FNV-1a hash |
FNV-1 64-bit | 64-bit FNV-1 hash |
FNV-1a 64-bit | 64-bit FNV-1a hash |
Custom FNV-1 | FNV-1(a) hash with custom parameters |
Note that actual list of algorithms in this section depends on version and localization of operating system. Some of the following algorithms may not be available in old or localized versions of operating system.
